Modified Approximate Dct for Image Compression Using Efficient Binary Adder

Image processing became a big challenge in the multimedia usage for processing the images with low power and high efficiency. For processing images, DCT (Discrete cosine transforms) are utilized for compression because of its advantages over the energy consumption. In existing methods, they used Approximate DCT with fast algorithm and regular pipelining structure for reducing the design complexities. Because of the recursive nature in the existing design, high speed applications are becoming tedious. In our proposed system, we are using Modified Approximate DCT transforms with efficient binary adder circuits. The proposed solution possesses reduced number of gates and logic realization becomes easy for implementation.
