WebPages 11 - 39. Abstract. Compression schemes can be divided into two classes: lossy and lossless. Lossy compression schemes involve the loss of some information and data … The design of data compression schemes involves trade-offs among various factors, including the degree of compression, the amount of distortion introduced (when using lossy data compression ), and the computational resources required to compress and decompress the data. … See more In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or See more Lossless data compression algorithms usually exploit statistical redundancy to represent data without losing any information, so that the process is reversible. Lossless compression is possible because most real-world data exhibits statistical … See more Image Entropy coding originated in the 1940s with the introduction of Shannon–Fano coding, the basis for Huffman coding which was developed in 1950. Transform coding dates back to the late 1960s, with the introduction of See more • HTTP compression • Kolmogorov complexity • Minimum description length See more In the late 1980s, digital images became more common, and standards for lossless image compression emerged. In the early 1990s, lossy compression methods began to be widely used. … See more The theoretical basis for compression is provided by information theory and, more specifically, Shannon's source coding theorem; domain-specific theories include algorithmic information theory for lossless compression and rate–distortion theory for lossy compression. … See more It is estimated that the total amount of data that is stored on the world's storage devices could be further compressed with existing compression algorithms by a remaining average factor of 4.5:1.

An image compression technique — JPEG [3] divides the image into blocks 8*8. After that, the two-dimensional Discrete Cosine Transform (DCT) is applied to each of these 8×8 blocks. Equation (1) is the DCT function. WebData compressioncan be viewed as a means for efficient representation of a digital source of data such as text, image, sound or any combination of all these types such as video. The goal of data compression is to represent a source in digital form with as few bits as possible while meeting the minimum requirement of reconstruction of the original. prayer short for class
