Progressive trellis-coded space-frequency quantization for wavelet image coding
نویسندگان
چکیده
This paper addresses progressive wavelet image coding within the trellis-coded space-frequency quantization (TCSFQ) framework [1]. A method similar to that in [2] is used to approximately invert TCSFQ when decoding at rates lower than the encoding rate. Our experiments show that the loss incurred for progressive transmission is within 1 dB in peak signal-to-noise ratio and that the progressive coding performance of TCSFQ is competitive with that of the celebrated SPIHT coder [3] at all rates.

Progressive image coding using trellis coded quantization
In this work, we present coding techniques that enable progressive transmission when trellis coded quantization (TCQ) is applied to wavelet coefficients. A method for approximately inverting TCQ in the absence of least significant bits is developed. Results are presented using different rate allocation strategies and different entropy coders. The proposed wavelet-TCQ coder yields excellent codi...
متن کاملUniversal trellis coded quantization
A new form of trellis coded quantization based on uniform quantization thresholds and "on-the-fly" quantizer training is presented. The universal trellis coded quantization (UTCQ) technique requires neither stored codebooks nor a computationally intense codebook design algorithm. Its performance is comparable with that of fully optimized entropy-constrained trellis coded quantization (ECTCQ) fo...
متن کاملA wavelet packet image coding algorithm based on quadtree classification and UTCQ
In this paper, we present a wavelet packet image coding algorithm based on quadtree classification and UTCQ. It is composed of four parts: (1) wavelet packet decomposition and best basis selection based on a new cost function, (2) a quadtree classification procedure, used to classify the wavelet packet coefficients into two sets: a significant one and an insignificant one, (3) the universal tre...
متن کامل1 Subband Image
This chapter presents an overview of subband/wavelet image compression. Shannon showed that optimality in compression can only be achieved with Vector Quantizers (VQ). There are practical diiculties associated with VQ, however, that motivate transform coding. In particular, reverse waterrll-ing arguments motivate subband coding. Using a simpliied model of a subband coder, we explore key design ...
