Low Complexity Based DCT Approximation for Image Compression using Hybrid Adder

The main objective of this project is to develop a demonstrative model of low complexity based DCT approximation using hybrid adder. The proposed method of Hybrid adder is used in DCT approximation technique for video processing system such as HEVC requiring low energy consumption needed for multimedia market has led to extensive development in fast algorithms for the efficient approximation of 2D DCT transform. DCT is employed in a multitude of compression standards due to its remarkable energy compaction properties. Multiplier free approximate DCT transforms have been proposed to offer superior compression .Hybrid adder is used for low complexity of DCT approximation. Hybrid adder is used to achieve low power consumption of 8.363 watts and area efficient of 1,600.In the method of carry look ahead adder is used for fast performances of DCT approximation for image compression algorithm thus consuming high power and area. The proposed DCT method is used for applications in live video broadcasting in television and cinema, high resolution format.
