Counting object using circular hough transform

1 view (last 30 days)
Good day all please i used circular hough transform (imfindcircle) to detect red blood cells in a microscopic image, can anyone please help me with the code that will help count the circles been detected? i am using Matlab 2017a. thank you and i look forward to your usual assitance.

Try imfindcircles.
imfindcircles uses a Circular Hough Transform (CHT) based algorithm for finding circles in images. This approach is used because of its robustness in the presence of noise, occlusion and varying illumination.
The CHT is not a rigorously specified algorithm, rather there are a number of different approaches that can be taken in its implementation.
The documentation goes into detail about the implementations.

cc = bwconncomp(detectedimage);
Number_of_cells = cc.NumObjects
