Contrast based quantization and rate control for wavelet coded images

14 years 11 months ago

Download foulard.ece.cornell.edu

A visually-optimal quantization and rate-control strategy based on results of recent contrast sensitivity and suprathreshold summation experiments is proposed. At suprathreshold c...

Quantized projection data hiding

14 years 11 months ago

Download www.gts.tsc.uvigo.es

In this paper we propose a novel data hiding procedure called Quantized Projection (QP), that combines elements from quantization (i.e. Quantization Index Modulation, QIM) and spr...
