Week of 11/23/09

Content:  This week Dr. Liang gave us lectures on imaging.  Also, Dr. Kahol gave us a lecture that included image filtering.  Filtering is commonly applied using masks in an image.  One of the topics included in the imaging lectures was image interpolation.  Interpolation can be used for functions such as scaling or rotating an image.  Another topic covered was image restoration.  Image restoration can be preformed by applying filters that adjust image intensity histograms or generally lighten or darken an image.  Image restoration can also be applied by using filters that sharpen or smooth an image.  Additionally, segmentation was a topic that was covered.  Segmentation can be preformed using filters such as edge detection filters.

Dr. Liang did some nice work organizing and summarizing the topics that he covered.  I also thought Dr. Kahol did a nice job expaining some filtering topics.  I liked getting to learn about the imaging topics that were covered this week.  The filters covered are so widely used that it is interesting to know more about how they work.  It was interesting to learn about the segmentation filters.  I can imagine how those filters are practical for a large number of purposes like object detection.

Here is a link to a open source program that is like photoshop.  If anyone doesn't have photoshop and wants to try image filters they could use the program at the link below.

It seems like GIMP has a lot of functionality that is similar to photoshop.
