Dr. H.B. Kekre, Dr. Tanuja K. Sarode, Sanjay R. Sange, Ankit Lahoti, Gauri Sawant . Image Reconstruction using Fast Inverse Half tone and Huffman Coding Technique. International Journal of Computer Applications. 27, 6 ( August 2011), 34-40. DOI=10.5120/3303-4518
Transmission of audio-video data over internet applications like Multimedia is increasing with fast pace. Biometric, Content Based Image Retrieval (CBIR), CCTV footage applications require huge storage of images in database. For such applications this combination of half tone with Huffman coding is useful. Half toning is lossy technique used in printing industry where binary image is required. Objective of achieving higher Compression Ratio by combining lossy half tone and lossless Modified Huffman coding techniques is used. Apart from standard operator like Floyd-Steinberg and Jarvis operators, Small and South-East operator are used. Halftone and Huffman coding technique is implemented on 10 different color images of size 512x512. For measurement of image quality, Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) and Structure Similarity Index (SSIM) are used. This hybrid technique can use for low bit rate video data transmission and mass image storage.
