Study on image tracking base on region growing

In order to improve the precision of image tracking, a new recognition arithmetic used in region growing is proposed. The method can capture the single connected component in image and extract it's feature. According to the feature, the method of categories to recognize entire single connected components is design. The recognition arithmetic solves inexact extracted feature, which is brought on by disturbance of background image near the object in ordinary recognition arithmetic. Base on the recognition arithmetic, a segmentation method by forecasting threshold is proposed. Using this segmentation method in image tracking, satisfying effect is gotten.
