September 17 2012

Data: Pictures in the data folder and some other pictures downloaded from libaray of congress.

Single scale: If both demension of the image is less than 500, then my implementation would only search for tranlation less than 15 in x,y directions.

Multi scale: If one of the demensions exceeds 500, I will build a image pyramid with each layer half the size of previous one. The size of top layer is less than 200 and bigger than 100.I will search for translation no greater than 5 in the top layer. As we goes down, each layer will search for extra translation less than 2 in x,y directions.

Matching Matrix: I implemented both ssd and ncc. Sometimes ssd is better while othertimes ncc is better.
