Abstract
In this report Discrete Cosine Transform (DCT) compression technique is used for Watermarking of an image.DCT is the lossy type of compression technique. The main aim of the paper is to use the better algorithm for compression among all Algorithms because it is suitable for all types of images. Moreover,a balanced compression ratio for data compression and image quality by compressing the vital parts of the image with high quality.Coding of DCT in MATLAB is done and after coding in MATLAB the interfacing in Xilinx through VHDL. It should be noted that image can also be loaded directly into FPGA. Coding in VHDL is done and Hardware implementation by interfacing the code which is in the PC (VHDL) software to Spartan 3 kit.So here we have used VHDL language and FPGA for our hardware implementation seeing the advantages in speed and memory of parallel processor.
