Project: SCODE- Scanned COmpound Document Encoder

Acronym: SCODE
Main Objective:
The main objective of this work is to investigate and develop an usable version of a MMP based scanned documents encoder, that is able to improve on the encoding performance of current state-of-the-art compound image encoders, like DjVu. In order to achieve this, some important tasks must be achieved:
- investigate and develop efficient methods for layer-based or block-based image segmentation, for optimisation of the overall
MMP-based encoder�s performance;
- optimise the dictionary adaptation process in order to increase the coding performance of MMP for the images corresponding to the
segmented layers or block types;
- efficiently implement a computational version of the method and investigate relevant functional optimizations, in order to reduce the
computational complexity of the algorithm without compromising its coding efficiency;
- perform a set of experimental tests in order to compare the encoding performance of the new method with the one of other
state-of-the-art methods.
