چکیده
In this paper we describe a structural compression technique to be used for document text image storage and retrieval. The primary objective is to provide an eecient representation, storage, transmission and display. A secondary objective is to provide an encoding which allows access to speciied regions within the image and facilitates traditional document processing operations without requiring complete decoding. We describe an algorithm which symbolically decomposes a document image and structurally orders the error bitmap based on a probabilistic model. The resultant symbol and error representations lend themseleves to reasonably high compression ratios and are structured so as to allow operations directly on the compressed image. The compression scheme is implemented and compared to traditional compression methods.

Selective CRLA based Layout Analysis and Text Region Extraction from Low Quality Document Images
This paper aims at detecting textual regions by separating graphical regions using Selective CRLA scheme and statistical textual properties on noise infected and low resolution newspaper images. A Bottom Up approach is adopted (i.e.) Selective Constrained Run Length algorithm (CRLA) is applied to obtain the layouts and region growing method over it, segments the homogeneous regions. Statistical...

Final Report : ATR Using Multiview Morphing Report Title
In 2005, reviewed current research literature in view morphing and matching for single views, and discussed a feature based approach to sparse view morphing that also shows promise for compression of the model data corpus. Worked on a new Bayesian approach for the problem from a mid-level segmentation problem. We obtained good results for feature-based morphing, as well as preliminary demonstra...
