excilent content ! now how would i loop this on file and save every picture ?

[@me965563]

This is exactly what I needed thanks

[@CarneyAsada101]

Thank you for this, it seems to be exactly what I was looking for! Reading about how to do it online is confusing, so it’s great to be able to watch you do it and make sense of what is going on!
I will be applying this to turn one photo into 12 photos for an Instagram grid. Is there anything I should consider about this video with that in mind?

[@raquelcosta2730]

Thank you for explaining everything so clearly! Definitely the best channel :)

[@jeepjr]

Teacher, first congratulations for the channel. I need your help, I have a simple image with a range of 5 placements where the quantity is identified, how do I identify the biggest color type red and say where the X,Y is, and if you can help me, and only for create an alert.

[@pysource-com]

You can check my other video on youtube about HSV colorspaces because there it's explained.
You need to sort the contours detected by the area and take the biggest one so you can locate the biggest color

[@iyshwaryakannan6677]

Hi sir, I wanted to display only the region of bounding box and make other region into some other color

[@jordanmhrnz132]

can you tell why my whole images is not being displayed?

[@shdnas6695]

Can someone explain why did he use "-" in column 5?
"rows", "cols", _ = img.shape
what is the underscore above doing??

[@adityawandile5905]

img.shape is returning tuple of three variable containing (rows,column and channel). this value is are store in rows, cols, _ respectively.
_ can used as an variable name so it act as an variable name to store the value of channel .

Well-done bro...thanks

[@gustavofelicidade_]

Thanks a lot

[@bulganamarsanaa1102]

hi Sergio how do we use this ROI on real time detection?

[@pysource-com]

Hi Bulgan, you will need to proceed in two steps:
1) Perform realtime object detection
2) Use the coordinates of the objects detected to extract the ROI

[@r.iyushofficial5318]

Awesome

Thanks for sharing, may I know how to read the huge big images? maybe 10000000*1000000, I don't know how to remove the limit of opencv.
