This study introduces an advanced wavelet packet coder for image compression. It adaptively optimizes both the transform and quantization for superior coding performance without needing prior image statistics.

Area of Science:

  • Digital image processing
  • Signal compression
  • Information theory

Background:

  • Previous work established space-frequency quantization (SFQ) for wavelet transforms.
  • Existing methods often require prior knowledge of image statistics for optimal performance.

Purpose of the Study:

  • To extend space-frequency quantization (SFQ) to wavelet packet transforms for a more general image coding framework.
  • To develop an adaptive coder that jointly designs the transform and quantizer without assuming input image statistics.

Main Methods:

  • Implementation of a wavelet packet coder utilizing SFQ.
  • Joint design of the transform representation and quantization strategy.
  • Adaptive selection of representation and quantization based on image characteristics.

  • Experimental results demonstrate excellent coding performance for specific image classes.
  • The coder adaptively selects the optimal representation and quantization for given images.

Conclusions:

  • The proposed wavelet packet coder offers a flexible and high-performance solution for image compression.
  • Adaptive joint design of transform and quantizer is effective, especially when image statistics are unknown.
  • This approach advances the field of image coding through generalized transform and quantization strategies.
