JPEG 2000 scalar quantization using an optimally frequency localized modulated lapped transform
JPEG 2000 is a lossy integer-to-integer transform-based compression method that first quantizes the separable 2-D wavelet transform coefficients, then entropy codes them. The imag...

Optimum Quantization Parameters for Mode Decision in Scalable Extension of H.264/AVC Video Codec
In the joint scalable video model (JSVM), selection of quantization parameters for mode decision (QPMD) and bit rate control (QPBC) is important for efficient coding performance. F...
