First of all, you need to snap images with a standard in there, such as the X-rite color checker chart
I never heard of those acronyms.
Otsu thresholding is not relevant here, unless it works to separate your leaves from background (like a uniform white or black background). Attach a few of your images.
You cannot compare greenness in different images unless you have a standard. You cannot simply use rgb2lab() and look at the b channel. That's what novices who are not trained in color science do. You must calibrate.

@Image analyst can you please share the extractNLargebloobs() for skin filteration??

To extract the N largest blobs from a binary image:
largestNBlobs = bwareafilt(binaryImage, N);
