VLSI Implementation & Analysis of Block Based Compression Algorithms

The VLSI Implementation and Analysis of Block Based Compression Algorithm is used to analyse the images within each pixel before the storage space processes and therefore the size of the memory gets reduced. Here, differential values are captured and quantized, then the differential coding scheme uses the concept of selecting the brightest pixel as the reference pixel. The difference between brightest pixel and successive pixel is calculated and quantized. Hence, their range is compressed and the spatial redundancy can be removed using BBC algorithm. Thus, the proposed scheme reduces the accumulation of error and also reduces the requirement of memory. Thus, the Peak Signal to Noise Ratio value can be improved and Bits per Pixel value can be reduced. This is created for any given input image and thus the input image may be of any form. After that the image is converted into the binary form or header file conversion and these files are implemented into Xilinx Platform Studio and analyzed.
