Spatially-selective quantization and coding for wavelet-based image compression

Recent developments in psychovisual modeling have led to improvements in wavelet-based coder performance. A spatially selective quantizer based on texture masking sensitivities is introduced, which hides distortion in high-contrast portions of images. Unlike other spatial quantization schemes, this...
