As more images and videos are becoming available in compressed
formats, researchers have begun designing algorithms for different
image operations directly in their domains of representation,
leading to faster computation and lower buffer requirements. Image
and Video Processing in the Compressed Domain presents the
fundamentals, properties, and applications of a variety of image
transforms used in image and video compression. It illustrates the
development of algorithms for processing images and videos in the
compressed domain. Developing concepts from first principles, the
book introduces popular image and video compression algorithms, in
particular JPEG, JPEG2000, MPEG-2, MPEG-4, and H.264 standards. It
also explores compressed domain analysis and performance metrics
for comparing algorithms. The author then elucidates the
definitions and properties of the discrete Fourier transform (DFT),
discrete cosine transform (DCT), integer cosine transform (ICT),
and discrete wavelet transform (DWT). In the subsequent chapters,
the author discusses core operations, such as image filtering,
color enhancement, image resizing, and transcoding of images and
videos, that are used in various image and video analysis
approaches. He also focuses on other facets of compressed domain
analysis, including video editing operations, video indexing, and
image and video steganography and watermarking. With MATLAB (R)
codes available as a download from the CRC Press website, this book
takes you through the steps involved in processing and analyzing
compressed videos and images. It covers the algorithms, standards,
and techniques used for coding images and videos in compressed
formats.
