چکیده
Said and Pearlman’s Set Partitioning In Hierarchical Trees (SPIHT) algorithm [5] is a well-known and efficient zerotree coding algorithm. However SPIHT’s high memory requirement is a major drawback for hardware implementation. In this paper we present a color image coding algorithm which requires much less memory during coding. Consequently the implementation complexity and hardware cost can be reduced significantly. Our experimental results show only a minor reduction of PSNR values when compared with the those obtained by the SPIHT codec illustrating well the trade-off between memory requirement and hardware simplicity.

A low memory zerotree coding for arbitrarily shaped objects
The set partitioning in hierarchical trees (SPIHT) algorithm is a computationally simple and efficient zerotree coding technique for image compression. However, the high working memory requirement is its main drawback for hardware realization. We present a low memory zerotree coder (LMZC), which requires much less working memory than SPIHT. The LMZC coding algorithm abandons the use of lists, d...

A new wavelet image coding algorithm was designed for color image compression in this paper.

The scheme works first by color space conversion, followed by raster scanning the individual subband for ...
متن کاملLow-complexity and low-memory entropy coder for image compression
In this paper, a low-complexity and low-memory entropy coder (LLEC) is proposed for image compression. The two key elements in the LLEC are zerotree coding and Golomb–Rice (G–R) codes. Zerotree coding exploits the zerotree structure of transformed coefficients for higher compression efficiency. G–R codes are used to code the remaining coefficients in a variable-length codes/variable-length inte...

متن کاملAdaptive wavelet packet basis selection for zerotree image coding
Image coding methods based on adaptive wavelet transforms and those employing zerotree quantization have been shown to be successful. We present a general zerotree structure for an arbitrary wavelet packet geometry in an image coding framework. A fast basis selection algorithm is developed; it uses a Markov chain based cost estimate of encoding the image using this structure. As a result, our a...
