Imaging Manipulation by Dr. Jianming Liang

The imaging manipulation presented in both lectures this week were interesting but rather hard to follow, especially the functions and equations for the various types of filters and masks.  They all seemed to blend together.  Although I love math, trying to follow the math examples for each type of manipulation was near impossible.  I understanding the masking, average, minimum and maximum filters, etc but fail to see when these would be used in clinical practice.  Obviously the filters and masks are needed to help clarify an image but I don't understand how you determine which one to use and when.  I appreciated the simplistic approach of using a photograph familiar to everyone instead of using actual medical imaging pictures. We could clearly see the results of each type of manipulation which was helpful but I don't understand when you would use a 3x3 versus a 5x5 mask, etc.. 

In addition, the slides are not posted for review.  Will these be posted soon?
