How can i count black spots in an image?

I cannot figure out how to count the black spots on the image that I have got after some processing applied. Below you can find attached two images that I want to count that marks. The ideal will be to count the marks and display an alert or something like this that says "Number of circles: #" I used regionprops with any results.

regionprops() works with white blobs, not black blobs. So just invert. But you can actually do the count with bwlabel():

[labeledImage, numberOfBlobs] = bwlabel(~binaryImage);

@Abdur Rahman search the image processing literature for published papers on animal counting:

For example here is one paper:

Kumar, S.[Santosh], Singh, S.K.[Sanjay Kumar], Singh, R.S.[Ravi Shankar], Singh, A.K.[Amit Kumar], Tiwari, S.[Shrikant],

Real-time recognition of cattle using animal biometrics,
