I have a stack of images (from a video) in which I want to track the evolution of the intensity of a particular color (blue in this case) across the stack, to give me a plot of color intensity vs time (see sample data here: https://www.dropbox.com/sh/wrkau2juu3yc2ll/AAB1pWigH8laqpzcbG_tejNsa?dl=0ho)
I know how to select ROIs and then use Multi Measure to get the gray scale intensity evolution. However, this is not suitable as it picks up too much noise from other colours.
Perhaps a solution would be to first convert the images so that everything non-blue (or not of the colour of interest) is white, and the shades of blue only remain? But I am not sure how to do this.
