Abstract :
We present the analysis, design and results for a reduced workload embedded block coding with optimal truncation (EBCOT) computational block, in JPEG2000 compression standard. We propose a new technique of rate distortion (R/D) control technique to reduce the amount of EBCOT computation that is required. In the proposed technique the compression rate requirement is relaxed, and instead we aim at maximizing the image quality while minimizing processing time by reducing the EBCOT workload.
