Digital Signal Processing and Computer Vision
Signal processing refers to the science of analysing physical processes. In digital signal processing the value of the signal is only known at discrete instants in time. The digital signals may be manipulated arithmetically or filtered with a digital filter. The new signal can be converted back to the analog world by using a digital-to-analog converter (DAC). Computer vision is used to embody the idea of automatically extracting useful information from an image. This information can be used in subsequent decision making. An image can be assumed to be a group of points that can be defined in a two-dimensional position by two variables.
