Abstract:
Module 3: Generating Shares We calculate intensity values of halftone image through Floyd algorithm this algorithm is used to hide data at background image. We calculate the PSNR & MSE values for both input & halftone image. Module 4: Overlapping of shares to generate decrypted image Embedding input image with watermark image by floyd and obtaining watermarked image as output. Dct coefficients are then quantized, coded and transmitted. The JPEG receiver decodes the quantized DCT coefficients, computes the inverse two-dimensional DCT of each block, and puts the blocks back together into single image. . For typical images, many of the DCT coefficients have values close to zero.
