By Jayanta Mukhopadhyay

As extra photographs and movies have gotten to be had in compressed codecs, researchers have started designing algorithms for various picture operations without delay of their domain names of illustration, resulting in speedier computation and decrease buffer requisites. Image and Video Processing within the Compressed Domain provides the basics, homes, and functions of a number of snapshot transforms utilized in photo and video compression. It illustrates the advance of algorithms for processing photographs and movies within the compressed domain.

Developing thoughts from first ideas, the booklet introduces well known picture and video compression algorithms, particularly JPEG, JPEG2000, MPEG-2, MPEG-4, and H.264 criteria. It additionally explores compressed area research and function metrics for evaluating algorithms. the writer then elucidates the definitions and homes of the discrete Fourier remodel (DFT), discrete cosine rework (DCT), integer cosine rework (ICT), and discrete wavelet rework (DWT). within the next chapters, the writer discusses middle operations, resembling picture filtering, colour enhancement, picture resizing, and transcoding of pictures and movies, which are utilized in numerous photo and video research methods. He additionally makes a speciality of different features of compressed area research, together with video modifying operations, video indexing, and photo and video steganography and watermarking.

With MATLAB® codes on an accompanying CD-ROM, this ebook takes you thru the stairs taken with processing and reading compressed video clips and pictures. It covers the algorithms, criteria, and strategies used for coding photographs and movies in compressed codecs.
