You forgot to attach your image. And I don't know what "if i find an of the command" means.

Label the more connected pixels. The pixels that did not get labeled are then the less-connected pixels.

but sir i have to use that less connected pixels image as a mask for pixel elimination from image so i couldn't find any command to just find pixels of less connectivity

m = bwareaopen (bw, 8);
lessconnected = bw & ~m;
