Abstract:

By using irregular sampling, an image may be digitized by concentrating sampling in areas of interest and reducing sampling in other areas. With this approach storage required for the digital image is more efficiently used and is usually reduced. This thesis explores an interactive method for reconstructing a compressed image. An interactive method allows human intuition to be combined with the speed and versatility of a computer. The user is able to guide the reconstruction through difficult cases of loop connectivity, branch linkup, and triangulation. MOSAIC, an element of MOVIE.BYU, is used for this reconstruction. This study shows that an interactive method has both good and bad points. Better reconstruction results when working with large, well-formed contours. When working with small, irregular shaped contours a significant loss of detail occurs. Keywords Image processing and Data compression.
