Unformatted text preview: JPEG compression algorithm. Find the compression ratio. [Answer] - Number of bits required without compression: 512x512x8bits - Number of bits after compression: Bits for DC + Bits for AC = approximately 17Kbits - Compression ratio = # bits without compression / # bits after compression = original image size / compressed file size = 11.85:1 (b) Decode the compressed bit stream and show the reconstructed image. Find the Peak Signal-to-Noise Ratio (PSNR) between the original and reconstructed images. [Answer] Reconstructed image - MAX = 255 for 8-bit input image - PSNR between the original and reconstructed image = 35.42 dB...
