FALL EE 5359 2010 MULTIMEDIA PROCESSING PROJECT REPORT Performance Analysis of Dirac Pro with H 264 Intra frame coding INSTRUCTOR DR K R RAO Poonam S Kharwandikar Department of Electrical Engineering University of Texas at Arlington Email poonam kharwandikar mavs uta edu ABSTRACT Dirac Pro is a hybrid motion compensated state of the art video codec that uses modern techniques such as wavelet transforms and only Intra frame coding It is an open technology designed to avoid patent infringement and can be used without the payment of license fees H 264 is the latest digital video codec standard which has proven to be superior than earlier standards in terms of compression ratio quality bit rates and error resilience However unlike Dirac it requires payment of license patent fees The objective of this project is to implement Dirac Pro and H 264 Intra frame coding only video codec encoder and decoder based on several input test sequences and compare there performance Analysis has been done on Dirac Pro and H 264 Intra frame coding only using QCIF and CIF video test sequences as input and the results have been recorded graphically for various parameters including bit rate PSNR SSIM and MSE Acronyms ATSC Advanced television systems committee BBC British Broadcasting Corporation CODEC Encoder decoder DCT Discrete cosine transform GOP Group of picture s HDTV High Definition Television ITU International Telecommunication Union ISO International Standards Organization JPEG Joint Photographic Experts Group JVT Joint Video Team MPEG2 Moving Picture Experts Group MSE Mean square error MV Motion vector QCIF Quarter Common Intermediate Format SSIM Structural similarity index Video Compression Information carrying signals like video may be compressed i e converted to a representation that requires fewer no of bits than the original signal A device or a program that compresses a signal is called an encoder and a device or a program that decompresses the signal is called a decoder An
