20 April - Issue in WBC Background Removal

Hi all,

My algorithm for background removal doesn't seem to be working for the actual images we got using the microscopes in Materials dept.

As you all can see (in the images), the RBC to WBC ratio in the images we got from the internet, is very low compared to that of the images we got in the Materials dpt. As a result, the algo doesn't seem to work on them.

So I have to write a second algorithm to segment the cells using purely the color profile which is guaranteed to work.

Anyway, the contrast stretching based one would work well in the long run, coz the actual images that we supposed to get with the correct magnificaton, are very close to the ones we got from the net. But as a fail safe, we'll have two algos for doing this.

This doesn't prevent the continuation of work, since the out put of the background elimination is a set of cvRect s. So others can proceed. At the same time, we can fine tune the background elimination algorithm.
