Most everyone would like to have a picture phone and lots of video clips or images on their web site. Image compression is an extensive field of studied aimed at this problem and has gained much popularity in recent years.
Many approaches exist for image compression.
This project focuses on the latter. An important historical example of convolution-based techniques is the Laplacian image pyramid. This is a multiresolution technique that decomposes an input into a series of bandpass images. The term 'pyramid' comes from the idea of viewing the set of bandpass images in a vertical stack. The advantage to this type approach to compression is that each bandpass image can be compressed with different levels of degradation.
