Efficient Image Compression and Retrieval using VLSI

A throughput productive FPGA execution of the 'Set Partitioning in Hierarchical Trees' (SPIHT) calculation is being utilized for the pressure of pictures. It utilizes intrinsic excess among wavelet coefficients and suited for both dim and shading pictures. It utilizes dynamic information structures thus it is self adaptive.The SPIHT calculation offers fundamentally enhanced quality over other picture pressure strategies, for example, vector quantization, JPEG and wavelets joined with quantization. It arranges the wavelet coefficients as per an importance test and stores this data in three separate records. Utilizing the pixel estimations of an info picture the picture is deteriorated into four sub-groups utilizing DWT. At that point, the decayed picture is compacted utilizing SPIHT codec. The compacted picture along these lines acquired is executed utilizing FPGA. SPIHT has a clear coding system and requires no tables. These make SPIHT a more fitting calculation for equipment execution.
