Picture processing is the process of converting an image to a digital format and applying various functions to it in order to create a better image or extract additional information from it. When the input is an image, such as a video frame or image, and the output is an image or attributes associated with that image, it is referred to as a signal time. In most cases, the Image Processing system treats images as two equal symbols while employing set approaches. It is currently one of the fastest expanding technologies, with applications in a variety of industries. Graphic design is also at the heart of research in the engineering and computer science industries. To distinguish audio processing conducted by computers from that performed by the biological auditory system, audio processing is commonly referred to as audio signal processing. Since the start of radio broadcasting in the 1920's, mechanical processing of audio signals has been used. The most common application of audio processing is to clean up or enhance an audio signal before it is broadcast.
