- Want to build your very own object detection app?
Tried, but maybe it took a little too long?
Just need a kickstart?
Well, I hear you! In this video you'll learn how to build your very own real-time object detection app with Tensorflow.JS and React.JS. In 15 minutes you'll be able to have your app up and running and detecting objects using a pre-trained COCO SSD model.
In this video you’ll learn how to:
1. Accessing the React.JS and Tensorflow.JS Computer Vision Template
2. Install Tensorflow.JS and setup the prebuilt models
3. Build a React.JS app that accesses your webcam
4. Make detections from your webcam in real time
5. Customise detection styling

That was the most rewarding result to a tutorial I have had in a long time. Great stuff!
Tremendous job, Nick. I watched several of your videos, but this one really pulls it all together for me. Thanks!
YESS, that's so good to hear @datapro007!
Excellent video! I usually use python and am kinda unfamiliar with JS, but you make it seem really easy! Thank you again!
Thanks so much, glad you're enjoying it!
The whole time I was looking for that mustache detection from the thumbnail 😂
Awesome video man! 🔥
🤣 my bad man!! Thanks 🙏 so much @Vikash!
impressive... webbase application is great to integrate with my company projects. Thanks a lot.
Can we by any means display the confidence score as well along with the object on the rectangle?
Hi is that possible to give video stream input from some url rather than camera input?
Great tutorial ! Thank you :-)
Awesome! Now I am trying to use custom model, apply it to React Native. Thank you for the walkthrough!
Awesome stuff, would love to see your code! I've been meaning to do something with RN for a little while now.
Hey! I have been trying to adapt this tutorial to React Native as well. I was wondering if you finished it?
Thanks for your walk-through, can I use my custom dataset? New in this field.
thank you very much this great tutorial. Can i use custom tf model by this method?
is there a way/library in js similar to sort/deepsort which we can use to track and assign unique ids on each object detected, example, if i wanted to count people i would need to assing an id to each person so i dont keep counting the same person over and over
very informative, thank you man!!!!
Anytime, thanks @Loui 🙏!
Hi, when running npm start the browser shows the error that it can not connect, even tried changing the port to 8080 in the package.jason but did not work , any reasons why it may not be working ?
Thanks
Thanks a lot for your amazing videos continue friend 🎉
Hi, thank you so much for this video! I am kinda new to programming and ai but I have only one question, could you implement yolov3/v4 into this instead of coco-ssd and how best could this be done? Thank you! Subbed
Heya @Steven, check out the custom object detection set of tutorials, I use 320x320 SSD, you could sub it out with a pre-trained Yolo model instead. The second and third video show how to train a custom model in Python then deploy it to TFJS: ua-cam.com/play/PLgNJO2hghbmhUeJuv7PyVYgzhlgt2TcSr.html
Thank you for the great video
Hi, can you help me with text detection in an image using tensorflow js or opencv js
thanks for the video. Somehow my screen turns black like a literal blackout. Is it because of the continous detection?
Hello Nick, do you have tutorial for android studio using java?
Im planning to use tenserflow object detection for grocery products. Is it possible to create my model for these items? But only using js not python
How can I feed it with new information and add new objects?
Is there a way to use your own gathered data for the model to use ?
please how can i create this app with my model object detection because i already have a custom model.js and i dont know how i can use it in an app like node-red or somthing please can you help me and thank you
Great tutorial 👏👏
GUSTAVO!! Thanks so much 🙏 🙏 🙏
Is it possible to do the exact same app but instead of my webcam, detect Objects of a fixed Image?
I tried to replace the Video with an Image, but there are no detections..
Tell me how to collect these datas in excel sheet as a attendance like if someone is not using mask that persons name get recorded in a excel sheet how to do that and if I want to do in a software how to do that as well
awesome tutorial!
Thanks so much @Justin!
Love it and subscribed.
Thanks sooo much!!
Hey, nice video, can I use a custom deep learning model instead of the COCO Model. I was building a similar application, but for fight/violence detection.. I have the model ready, how can I integrate it.
unfortunately no 😅😅@tinat205
Just Awesome.....!!!!
I cant get the rectangles to show. There is no errors in the console, and the detections are being logged out correctly. I have checked that the canvas size is correct, but cant figure out why they aren't showing
Dear Nicholas, can we change Webcam to other source. For instance to react-video or react-player?
Ooooh, haven't tested those out but they should work as long as it's a video input!
Thanks for the video . Liked :) . In your opinion . Which model is the most accurate for image/video background removal. Preferably one that I can use with tensorflow JS.
This is has probs been my fav, ua-cam.com/video/0tB6jG55mig/v-deo.html I believe it's also available via tfjs as well!
Great broo😎😎 cool project..
Waiting for Image caption Generator
Thanks 🙏 so much, I promise it's coming. A few more computer vision tutorials and I'm on it!
Sirr kindly reply mee.....which algorithm is used in this project plzz tell me
Hi just wondering, I wanted to upload my own custom model how would I do that
Hello Nicholas, I followed everything you did and the app compiles successfully but when I launch it in the browser it doesn't render the camera canvas even though Chrome detects that the app is using the camera and even asks for permission to access
I wonder if this is a problem with my webcam or is there something I need to check in the code ?
Heya! Let's dig into it, any errors in the console?
Thank you!!! Been trying for a while to get something decent working, I think Jupyter doesn't work with a CUDA dependency or something on my computer so it keeps crashing. Thank you very much!
Hmmm, any errors appearing when you run it?
After writing npm start in the terminal,it was compiled successfully but still the link was not working in the browser.
What should I do now?
Please help me out.
Thanks for this great video! Can we also use this example on react-native with phone camera?
Heya @Hakan, the underlying model can be used but it needs to be reskinned for React-Native.
Dear Nicholas , how could i use same this functions by python language ?
Great tutorial 👏👏.. can you make a blind assistance system: real-time object detection using TensorFlow with distance and voice?
Hmmm, interesting! Yah, i'll add it to the list!
Is it possible to upload it to heroku ? If so, how ? i'm trying to deploy but i get several erros, even if i change heroku's bluidpacks to nodejs
Can you help me?
You should be able to, might require some config as you said. I've got an example of deploying via IBM cloud. Might not be exactly the same but should give you an idea of build steps.
Do I need to install TensorFlow to run this?
I have question that is it possible to do sign language detection for any mobile device like if a person who cannot speak and uses sign language to communicate if we can understand what he is trying to say in case of any emergencies.
Heya @Jason, yep, I've had a chat to a few people fluent in ASL and the number one piece of feedback is that people tend to sign VERY fast so the model has to be quick. Additionally the model needs to be extended a little to leverage action detection rather than just frame by frame detection.
thx very much for ur effort
when i type npm start is says i am missing a script?
It's working thanks 👍
Awesome!! What's next?!
Thank you for informative video, I have one question, how I can use and load my own custom model ?
Great question! This is done in two parts, first you need to train a custom model (ua-cam.com/video/pDXdlXlaCco/v-deo.html), then you can export and convert to a TFJS friendly format and load the custom model into your React app (ua-cam.com/video/ZTSRZt04JkY/v-deo.html).
@@NicholasRenotte thank you for the support , I will give it a shoot.
Your support is highly appreciate
Anytime! You're welcome

Even if I do look hella seedy @Ashley 🤣!
How to restrain detection upto PPE_Detector ? Any idea brother
hey bro
Im using handtrack.js for my project and Im facing a problem of detection mutliple objects of class
I need to detect only one detection for a class for example (for the class hand if i have two hands in frame it should detect only hand) i checked in the official site it says something maxnumber of Detections but could able to implement this could u help me to regarding this MaxNumber of detection value how to implement it js
Heya @Doli, haven't used it before but looks like you can limit it based on max_num_boxes using the configuration you pass through. Check out the home page of the documentation it shows an example of it set to 20, try dropping it down: github.com/victordibia/handtrack.js/
Thanks for this helpful video. Can you make one that detects abnormal behavior as well using JS
Great Video. Do you have a tutorial that can detect a person and what he/she is holding. and can alert if it is dangerous or not the object that he/she is holding. Thank you and more power. I hope to hear you soon. best regards
Nic, I trained my data using yolo, so how do i convert that model to TF.js
Depends, there's a few tfjs converters out there. Try looking at this: www.tensorflow.org/js/guide/conversion
hello, after npm start, it tells me that it cannot connect to the local server, I am working in mac, thank you, your videos are so great
why Line 24:14: 'net' is not defined no-undef ?
Nicholas I have a problem, every time that i try to run the project using "npm start" my browser open and show the message "localhost refuses the connection". I've already tried to disable the firewall and give EDGE public and private network permissions, but somehow it still not working, can you help me please?
did you find the solution? i am facing the same problem
Thanks a lot sir
npm install is not working. It shows error in that. Do you have any idea why is this happening?
The video is really great!!🙏

Please help me out!!!
Heya @Diya, can you compare your code to the baseline code from the description. Likely the net model hasn't been defined.
I've been looking for this tutorial...thanks for sharing. My question is how can I add face mask image for detector to dictate face only with the face mask to cover the face?
Heya @Benjamin! Awesome, thanks for checking it out. Hmm, did you mean like masking out the region or applying an overlay with a mask image?
@@NicholasRenotte Thank you for your kind response. Yes I mean applying an overlay with a mask image.
REALLY nice
Thanks @Ahsan 🙏!

Hi nickol , why tf js is lighter than normal tensorflow ,
I just want to ask something. How to solve this when the result is:
Compiled with warnings
./src/App.js
Line 2:25: 'useState' is defined but never used
no-unused-vars
Line 3:13: 'tf' is defined but never used
no-unused-vars

Search for the keywords to learn more about each warning.
To ignore, add // eslint-disable-next-line to the line before.
I need help. Thanks!
Heya @Mong, is the app running? We exclude the dependency so that the model only loads once. These look like warnings rather than errors.
@@NicholasRenotte when the browser started to develop, the browser only have color gray without camera even though i allowed using mic and camera.... so should i do this in line 63 "useEffect(()=>{},[]);" ???
@@mongji5217 nope, you need your webcam to activate and render first! Are there any errors in the console?
GREAT video bro! can u make detector with text to speech either? i'm sure it will be more cool

How to create PPE_Detector ? using Tensorflow.JS and React.JS ?
dear @nicholas Renotte,
why the detection is very slow and does not respond quickly. Does tensorflow see the PC specs, the detection only appears once and it's very slow, even though I've tried to reduce the time in the set interval function, pleeasee help this is very awesome projects
Heya @hai coders, hmmm, what type of machine are you running it on?
@@NicholasRenotte cpu AMD A 10 Radeon hd Graphics windows 10 education
@@haicoders737 hmmm, should be fine, is that a dedicated graphics card?
@@NicholasRenotte no this is not a dedicated graphics card .but my console.log, noted a warning not supported by webGL. does it matter?
@@haicoders737 i believe webGL allows you to leverage your GPU. It might be a little slower if you're using the non webGL backend just a heads up, should still work though!
I have live feed from the ptz IP camera, no one on youtube properly explained how to take input from the ptz IP camera. Plzz make one video on this 😅😅
Anyone tell me how to add audio as output for the detected items 🥲
Can we instead of giving webcam as input, give a video as input?
Ah, yes, I can't remember how I did it but it's definitely possible. Easier to do it with Python
