Wavelets

Project 1: Multiresolution Spline Curve Modeller

This assignment really doesn't have much in the way of interesting images to look at. It was more of a "make sure you have the background" type assignment. Maybe I'll put images up if I have time and I think it's worth it.

Project 2: Image Compression

Image compression using the Discrete Cosine Transformation (JPEG), the Harr Wavelet Transform, or the Linear B-Spline Wavelet Transform. After the transform is completed, a simpleminded compression routine gives the compression.

Project 3: Multiresolution Terrain Viewer Using B-Spline Wavelets

A multiresolution terrian viewer. In this project, we took a terrain data set, read it in, resampled it for easy usage in a B-Spline Wavelet Transform, and allowed the terrain to be viewed at different "resolutions" (i.e. different number of wavelet coefficients used during reconstruction).

Project 4: Mesh Simplification

A program to compress triangle meshes. This project uses a very simple edge collapse simplification scheme.

Final: Mesh Simplification using Wavelets

Looking into using Wavelets to compress a discretely sampled 3D polygonal mesh.
