Project 3: Feature Detection

Blob Detection and User assissted ROI option.

I am assumming that you will be first doing Blob detection in your breast image (if you propose something different you need to convince me of it and it will need to be approved). This blob detection algorithm is part of the work of this project. To make things easier, I will allow you to require the user to first signify an area of interest, which we will henceforth call Region of Interest (ROI), by in your applications GUI window containing the image lettting the user with their most click and drag to create a rectangle. This area the must be displayed separately as the active image (in essence cropping) and then you can do the processing on this. The idea is that the user has assisted with indicating a smaller area that might contain a blob. This can significantly make your blob detection easier with simpler methods. It is not required that you do the ROI option. It is a tradeoff between some GUI programming and making a more complex algorithm to detect blobs.



Here we see the user
with their mouse specifying
the region of interest- red
rectangle - that is then shown on right. This is the image that will now be processed by the system.
