SAR Image Compression using SPIHT Algorithm

Abstract

This paper discusses the design and implementation of SAR image compression based on the set partitioning using hierarchical trees (SPIHT) coding algorithm.SAR images are considered in our work due to large scope in its application area which requires reduction i.e. is compression.As per the survey SPIHT algorithm has achieved prominent success in image compression.Here we use a modified version of SPIHT for two dimensional signals which is lossless.Set partition coding is a procedure that recursively splits groups of integer data or transform elements guided by a sequence of adaptive threshold, and presented in octree form.
