Analyses of Higher Order Metrics for SPIHT Based Image Compression

The increasing use of digitized images has led to the need to compress such imagery to allow economical storage and fast data transfer. Despite all the advantages of JPEG compression schemes based on DCT namely simplicity, satisfactory performance, and availability of special purpose hardware for implementation; these are not without their shortcomings. The input image needs to be blocked which...

DCT Based SPIHT Architecture for Hyperspectral Image Data Compression

of the Thesis DCT Based SPIHT Architecture for Hyperspectral Image Data Compression by Jieming Xu Master of Science in Electrical and Computer Engineering Northeastern University, August 2016 Prof. Vinay K. Ingle, Adviser The wavelet transformation is leading and widely used technology in transform coding. Many coding algorithms are designed for this transformation based on its unique structure...

Highly scalable image compression based on SPIHT for network applications

We propose a highly scalable image compression scheme based on the set partitioning in hierarchical trees (SPIHT) algorithm. Our algorithm, called highly scalable SPIHT (HS-SPIHT), supports spatial and SNR scalability and provides a bitstream that can be easily adapted (reordered) to given bandwidth and resolution requirements by a simple transcoder (parser). The HS-SPIHT algorithm adds the spa...

Improvements of SPIHT in Image Compression- Survey

Set partitioning in heirarichal trees (SPIHT) is a widely used compression algorithm for wavelet transformed images. Of most algorithms developed, SPIHT algorithm ever since its introduction in 1996 for image compression has received a lot of attention. Though SPIHT is much simpler and efficient than many existing compression techniques as it’s a fully embedded codec , provides good image quali...
