Abstract: The present invention relates to an encoding apparatus, an encoding method, an encoding program, a decoding apparatus, a decoding method and a decoding program for adaptively controlling an encoding bit rate. Coefficient data obtained using wavelet transform is quantized, and segmented into bit planes. The coefficient data is entropy encoded from the bit plane of the MSB in a direction from an upper bit position to a lower bit position. Entropy encoding is stopped at a bit position where an amount of code has reached a target amount. On the bit plane, the coefficient data is entropy encoded from a lower frequency region to a higher frequency region. Data greatly affecting subjective image quality of a decoded image is selectively output while the amount of code is easily controlled.

Reordering wavelet coefficients for improved encoding
Henrique S. Malvar
- 26 Mar 1999
TL;DR: In this paper, an encoder reorders quantized wavelet coefficients to cluster large and small wavelets into separate groups without requiring the use of data-dependent data structures, and the coefficients are then adaptively encoded based on a run-length code which continuously modifies a parameter that controls the codewords uses to represent strings of quantized coefficients.
