hi, I am a new user of MATLAB image processing tools and i want to process an image of sputum cells sample to detect how many cells are there in one sample image. but in some case, two or more cell are overlap. the problem are, the are difficult to find a suitable features to detect the cell as the cell are not fix in shape, size, length. i try to detect and count the nucleus inside the cell however there some cells that have no nucleus. so how do i detect the cell as single cells.i here attach a sample image. thank you.
