FREQUENCY CONTENT ORIENTED MODIFICATION OF QUANTIZATION MATRIX IN DCT – BASED COMPRESSION
Image compression quantization matrix
2006/1/12
In order to improve the compression rate for comparable values of error metrics, we propose a method to modify the standard quantization matrix used in JPEG, according to image frequency content. Unli...
A Study on the Quantization Scheme in H.264/AVC and Its Application to Rate Control
Quantization Scheme H.264/AVC Rate Control
2004/12/31
Compared with previous video coding standards,H.264/AVC employs a division-free quantization scheme. The relation
between quantization parameter and quantization step changes from general linear to e...
