Performance Analysis of SVD and SPIHT Algorithm for Image Compression Application
نویسنده
چکیده
This paper deals with performance evaluation of well known image compression algorithm i.e. wavelet based image compression Set Partition in hierarchical Tree (SPIHT) and decomposition algorithm known as Singular Value Decomposition (SVD). Due to multi resolution nature of wavelet transforms, SPIHT provides better image compression at higher compression ratio. The techniques are implemented in MATLAB and compared using the performance parameters PSNR, MSE, CR and compressed size. Images obtained with SPIHT technique yields higher compression ratio and better visual quality. KeywordsImage compression, Singular Value Decomposition (SVD), Discrete Wavelet Transform (DWT), Set Partition in hierarchical Tree (SPIHT).

متن کاملModified SPIHT Image Coder For Wireless Communication
The Set Partitioning in Hierarchical Trees (SPIHT) approach for still image compression is one of the most efficient embedded gray image compression schemes till date. The algorithm relies on a very efficient scanning cum bit-allocation scheme for quantizing the coefficients obtained by a wavelet decomposition of an image. In this paper, modifications of the SPIHT compressor without arithmetic ...
