The compressor which is projected here has the capacity to change between the approximate and exact modes it has lower power, low accuracy, and high speed in the approximate phase. In exact as well as in approximate modes these dual quality compressors will exhibits different level of accuracy, delay and power dissipation. So during run time their accuracy, speed, and power may variant vigorously by employing these compressors in design of parallel multipliers. The same compressors are used with different bit size like 8, 16, 32, 64 bits the tabular column is created between different bit levels to know the difference between them and the area, speed, and delay are also calculated for different bits. Error correction is calculated at the output for each and every bit. And this compressor are used in the image processing application here smoothing technique is considered.
