WebCompression occurs when the output is a single code instead of a longer string of characters. This code can be of any length and always has more bits than a single character. The LZW algorithm does not analyze the incoming text. It simply adds every new string of characters it sees into a code table. 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 fast Fourier transform (FFT) coding in 1968 and the Hadamard transform in 1969. An important image compression technique is the discrete cosine transform (DCT), a technique d…
