摘要： In one exemplary embodiment, a tracking system for region-of-interest (ROI) performs a feature-point detection locally on an ROI of an image frame at an initial time via a feature point detecting and tracking module, and tracks the detected features. A linear transformation module finds out a transform relationship between two ROIs of two consecutive image frames, by using a plurality of corresponding feature points. An estimation and update module predicts and corrects a moving location for the ROI at a current time. Based on the result corrected by the estimation and update module, an outlier rejection module removes at least an outlier outside the ROI.

摘要： In one exemplary embodiment, an object region tracking and picturing module is constructed on a moving platform of a mobile end and a remote control module is constructed on another platform for an image object region tracking system. The two modules communicate with each other via a digital network for delivering required information. The object region tracking and picturing module uses a real-time image backward search technology to store at least an image frame previously captured on the moving platform into a frame buffer, and start tracking an object region from the position pointed out by the remote control module to a newest image frame captured on the moving platform, then find out a relative position on the newest image frame for the tracked object region.

摘要： A pixel region-based image segmentation method is disclosed. When an input image is retrieved, pixels thereof are sequentially scanned row by row. Signs of unmarked pixels of the input image are determined according to region features of neighboring pixels of each pixel and pixel update information is recorded to generate a region sign update data table and a region sign feature data table. The pixels of the input frame are further scanned row by row to retrieve signs of the pixels and region signs of the pixels are determined and updated according to the region sign update data table.
