Automated Pipeline for Color Analysis in ImageJ (Fiji)
In this video, I share a macro (available here: doi.org/10.5281/zenodo.5595203) that automates the extraction of summary statistics from channels of three colorspaces (RGB, Lab, and HSB). This macro functions to 1) open an image from a directory folder, 2) threshold the image to segment out the object of interest from the background then "clear" the background so it is completely black, 3) separate the image into the component channels for each color space, 4) extract summary statistics for each channel in each colorspace, 5) export these summary statistics to a .csv file.
I also provide an optional R script (available here: doi.org/10.5281/zenodo.5595203) to automate the reformatting of the .csv file with the summary statistics from the imageJ so each channel is transposed into distinct columns. The final .csv file produced by running this code should have each image as a row, with each summary statistic (mean, mode, min, max, etc.) for each channel in each colorspace presented in a separate column for that image (row).
Step-by-step directions, color analysis macro, and R script available for download here: doi.org/10.5281/zenodo.5595203

How to Batch Crop Your Images in ImageJ / Fiji
Переглядів 17 тис.3 роки тому
In this video, I share two options for quick and efficient cropping of large image sets in ImageJ/Fiji. Two options provided are: 1) A protocol to batch crop a set of images as an "image sequence". This approach works best on sets of images that are captured at the same scale and where the region of interest (ROI) is in the same location in every image. 2) A protocol that uses a macro (availabl...

Then I specify the dimensions I want, then you can drag and move the box to the exact spot. Then press ctrl + x to crop I believe. I haven't got this to work as a macro, but I just do this individually to each image that I want to crop, but still be uniformly sized.

    Hi! I ran into some problems with the program mistaking the object for the background and I don't know if you would be able to help me. When I run the program at first it looks fine since it shows the background black but when looking at the measured images at the end it shows the other way around, with the object as black. I don't know if the final image is wrong or just the entire process. I tried both automatic and customized thresholding. Thanks

    • @CFStrock
      @CFStrock 2 роки тому

      Hi Jing- Definitely sounds like a thresholding issue/incorrect thresholding settings for your images. The summary stats from all the channels will reflect the pixels that are not blacked-out in your final images that are saved back to your working directory. I think the solution lies in finding the correct thresholding values for your specific image set.

    • @jing107
      @jing107 2 роки тому

      ​@@CFStrock Hi. I don't know why but I couldn't find the correct thresholding values so the object doesn't go black. In the end, since I'm working with beakers which have an easy shape, I decided to crop them by hand. Thank you for answering though!
