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 ...

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...
