Dr. Lakaemper,

 

In home work 4, I attempted to use Roland Miezianko’s method in detecting motions. Implementation is in Matlab but the coding style is not “Matlab-Oriented.” And, that may be the cause of the slowness of the implementation. Of course, this reinforces our decision to implement Roland’s method in C# (or C++).

 

The sequence in which the Matlab code should be ran: hw4.m first, then runDetection.m. Hw4.m contains the functionalities to create the eigenvector that is used to construct a projection matrix as well as find the motion measure (in runDetection.m). hw4.m generates projPCA, a vector of size 1x1200, used to store eigenvectors (computed in the initialization step).

 

Motion measure is the highest eigenvalues of a particular block/region that will determine whether or not a motion appears in the region. runDetection.m performs the motion detection by finding the motion measure.

 

Due to the speed problem (I ran the Matlab implementation on my IBM ThinkPad Tablet X41 and it crashed a couple of times), I just have to display the region number with motion per frame and.

 

See you in class this evening.
