The input image seems a bit challenging, yet you can try the following basic methods and check the results.
One way:
  1. Convert the image to binary with best fit thresholding (or see other segmentation appoaches)
  2. Use bwlabel
[L,n] = bwlabel(binary_image) % here n gives the number of connected objects
or
2. For measuring the properties of retions, like calculae area, you can look at regionprops
Good Luck!
