Counting points on a leaf in Wolfram

[floravf80 (Flora Vosoughi)]

Hi everybody,

I am a beginner in Mathematica and would like to ask how I can count the points on a leaf. Is there a specific method or function for this?
I would appreciate any guidance.

Thank you!

The code I wrote and the result I got is:

img = Import["path/to/your/leaf_image.jpg"];

bwImg = Binarize[img];

spots = MorphologicalComponents[bwImg];

numSpots = Max[spots];ImageCollage[{img, Colorize[spots]}]

Not perfect but you could use color based segmentation

mask = Binarize[ColorDetect[img, ColorsNear[Brown]], .1]

Then use the centers of the morphological components

HighlightImage[img, 
 ComponentMeasurements[MorphologicalComponents[mask], "Centroid"]]

Thank you very much for your guidance.

I have tested 3 images and obtained the results and errors. I would greatly appreciate it if you could kindly review them and provide your feedback.
