BASICS OF VIDEO IMAGE-ANALYSIS

In analytical chemistry, numerous applications involve the creation of images, which are generally processed by computer in order to extract relevant informations. The complete chain of video image analysis is presented here under a simple and comprehensive form. After recording, images are first digitized and stored in the memory of the computer. They are then processed to eliminate the noise and the irrelevant information. An other step of image analysis consists in the extraction of features of objects. At last, methods of pattern recognition may be applied on extracted information, in order to automatically identify the nature of the element of the recorded image.
