Designing filter

I want to design a filter that can recognize objects of a particular shape e.g round shape, within an image and then return a high pixel value at each spot where it identifies an object. Any help would be appreciated.

Hi @ch basit,

I understand that you want to design a filter, that can recignize objects of a particular shape within an image anf then return a high pixel value at each spot where it identifies an object. Below steps can help you in getting started:

1. Preprocess the image
2. Detect round objects using "imfindcircles" (Hough transform) or circularity-based filtering with "regionprops".
3. Mark locations in output image

To understand more about "imfindcircles" refer to the following documentation: https://www.mathworks.com/help/images/ref/imfindcircles.html and for "regionprops" refer https://www.mathworks.com/help/images/ref/regionprops.html

Hope this helps!.
