Image Representation Made Easy

Image representation (description) involves several steps until they are reconstructed for comparison. The steps are mapping, optimization, parametrization, and reconstruction. This book describes the step by step process of representing images while exploiting the exciting properties of the representation tools Spherical Harmonics (SPHARM) and Singular Value Decomposition (SVD) individually in a comparative fashion, and under one platform. The orthogonal relationship between the parameters of the listed tools extracts the image data during the parametrization phase after the mapping and optimization processes. A comparative analysis is done in the end for both the tools focusing on the compromise between image quality and compression after the reconstruction phase and are ready for comparison. The text also includes least square error graphs for each tool, which makes the comparison easier for the reader
