Image and Video Processing in the Compressed Domain by Jayanta Mukhopadhyay PDF

By Jayanta Mukhopadhyay

As extra pictures and movies have gotten to be had in compressed codecs, researchers have all started designing algorithms for various snapshot operations without delay of their domain names of illustration, resulting in speedier computation and reduce buffer necessities. Image and Video Processing within the Compressed Domain offers the basics, homes, and purposes of a number of snapshot transforms utilized in photograph and video compression. It illustrates the improvement of algorithms for processing photos and movies within the compressed domain.

Developing options from first rules, the ebook introduces well known photo and video compression algorithms, specifically 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 houses of the discrete Fourier rework (DFT), discrete cosine remodel (DCT), integer cosine remodel (ICT), and discrete wavelet rework (DWT). within the next chapters, the writer discusses center operations, similar to snapshot filtering, colour enhancement, photo resizing, and transcoding of pictures and movies, which are utilized in numerous picture and video research ways. He additionally specializes in 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 e-book takes you thru the stairs interested by processing and studying compressed video clips and pictures. It covers the algorithms, criteria, and strategies used for coding photographs and video clips in compressed codecs.
