Image Processing
Abstract
Image processing consists of a wide variety of techniques and mathematical tools to process an input image. An image is processed as soon as we start extracting data from it. The data of interest in object recognition systems are those related to the object under investigation. An image usually goes through some enhancement steps, in order to improve the extractability of interesting data and subside other data. Extensive research has been carried out in the area of image processing over the last 30 years.Image processing has wide area of applications. Some of the important areas of application are business, medicine, military and automation. Image processing has been defined as a wide variety of techniques that includes coding, filtering,enhancement, restoration registration, and analysis. In many applications, such as the recognition of three-dimensional objects, image processing and pattern recognition are not separate disciplines. Pattern recognition has been defined as a process of extracting features and classifying objects. In every 3D-object recognition system there are units for image processing and there are others for pattern recognition. There are three different approaches to image processing: a. Analog processing: This approach is very fast since the time involved in AD and a DA conversion is saved. But this approach is not flexible since the manipulation of images is very hard. b. Digital processing: This approach is slower than the analog approach but is very flexible, since manipulation is done very easily. The processing time of this approach is tremendously improved by the advent of parallel processing techniques. c. Heuristic processing: This is a smart way of processing but it is conditional since it involves probabilities. The dominant approach is the digital processing approach because it is very flexible.
