Chapter 6 Digital Video And Image Compression Pdf Data Compression Video Chapter 3 data storage this chapter discusses how different data types are stored in computers. it describes how integers, reals, text, audio, images, and video are stored. Image compression addresses the problem of reducing the amount of data required to represent a digital image. the underlying basis of the reduction process is the removal of redundant data. from a mathematical. viewpoint, this amounts to transforming a 2 d pixel array into a statistically uncorrelated data set. the.
Digital Image Processing Chapter 8 Pdf Data Compression Computer Vision In this c hapter w e fo cus on source co ding (compression) and standards for compression. information co ded at the source end has to b e corresp ondingly deco ded at the receiving end. co ding can b e done in suc haw a y that the information c ontent is not lost; that means it can b e reco v ered fully on deco ding at the receiv er. In the literature, the terms source coding, data compression, bandwidth compression, and signal compression are all used to refer to the process of compression. Figure 3.3.1: an image stored as a 1440 1468 array of pixels along with a close up of a smaller 8 8 array. a lot of data is required to display this image. a quantity of digital data is frequently measured in bytes, where one byte is the amount of storage needed to record an integer between 0 and 255. Understand the application of lzw compression, huffman encoding, and jpeg compression. understand the luminance and chrominance downsampling. understand the indexed color algorithms. understand the dithering algorithms. understand pixel point processing in digital image processing.

List five different data types used in a computer. describe how integers are stored in a computer using unsigned, sign and magnitude, and two’s complement formats. The data compression book provides you with a comprehensive reference to this important field. no other book available has the detailed description of compression. Reduce the size of the image, video, or audio data. • such methods are extremely vital in many applications that manipulate and store digital data. • informally, we refer to the process of size reduction as a compression process. we will define this process in a more formal way later. It explains different image types, including 1 bit, 8 bit grayscale, and 24 bit color images, highlighting their storage requirements and applications. the chapter also compares gif and jpeg formats, emphasizing their strengths and weaknesses in terms of compression and image quality.
