cell counting Matlab code?

hi

Could someone help with counting the number of cells that have been segmented in an image. i have segemented the cells and marked the outline of each cell. Now i need to count the number of cells present automatically.

CC = bwconncomp(BWImage)
CC.NumObjects

Where BWImage is the black and white image with each cell white.

Simply call bwlabel on your segmented image, and it will count them for you. You don't need the outlines that you got from bwboundaries() or bwperim() to do counting.

[labeledImage, numberOfBlobs] = bwlabel(binaryImage);

If you want other measurements (beyond the count), call regionprops():

measurements = regionprops(labeledImage);

hi, thanks for the answer the output is always ans = 1 , even though I have for example 100 cell.

Well then you didn't do the segmentation step in your process very effectively. What did you do?
