The Computer Automatic Recognition Character Of Numeral Instrument Dynamic Displayed

With the development of science and technology, the management means of every walk of life is changing into automatization or half automatization from manpower. Especially in order to real time supervise in chemical industry, metallurgy fields and other relative scurviness environment, and improving productivity and reducing miscarriage of justice for the factor of human made. Automatic control system can be adopted to realize the aim, it is a convenient and agile scheme by comparing the enactment condition and the recognized numeral of instrument to realize automatic control operation. So recognition the string of numeral instrument is very important, which is object of this thesis.The recognition system is a integrated real time computer vision system, which consists of image preprocess, string region location, string segment and character recognition. The preprocessing of image includes graying of color image , smoothing, linear transforming of gray, binarization, edge checking and so on. we use the region growth when there is only one instrument in image. In order to segment the string into...
