Images transmitted over the world wide web are an excellent example of why data compression is important. Suppose we need to download a digitized color photograph over a computer's 33.6 kbps modem. If ...
This is a design and fabrication of a CMOS image sensor with a non-uniform layout of pixels that enables the arithmetic Fourier Transform (AFT) algorithm to be used for image compression. A ...
Coding, information theory and compression provide a unified framework for quantifying, transmitting and summarising data. At its heart lies the concept of entropy, which measures the average ...
