Hi,

I have a binary image with many blobs. I want to know all the connected pixels to a particular pixel whose index I know before hand. How do i do that?

% Try following 
 CC=bwconncomp(binary_image); % Default 8 Pixel connected you can change it by 
 cc=bwconncomp(binary_image,disired_connected_value);

bwconncomp gives me all the connected components. My problem statement is that I have a particular pixel index. I need all the connected components to that pixel.

If I use bwconncomp I will get all the connected pixels and then I will run a for loop and search the blob which contains my desired pixel. This will be computationally expensive. Is there a better way?
