Abstract
A target detecting system and method for detecting a target from an input image is provided. According to the target detecting system and method, when a target is detected from an input image and there are moving areas in the input image, camera movement parameters are obtained, image frames are transformed, and movement candidate areas are extracted from the image frame and the previous input image frame. In addition, image feature information is extracted from the input image, and based on the movement candidate areas and the image feature information a shape of the target is extracted. Therefore, the target can be exactly and rapidly extracted and tracked.
Claims45
A target detecting method for detecting a target from an input image from a camera, comprising the steps of:
- a) obtaining camera movement parameters from a movement area in an input image from the camera, and correcting an image frame using the obtained movement parameters;
- b) extracting movement candidate areas from the input image frame and a previously input image frame;
- c) extracting image feature information from the input image;
- and
- d) extracting a target shape based on the movement candidate areas and the image feature information.
A target detecting system for detecting a target from an input image, comprising:
- a camera that obtains a target image to be detected and which transmits the obtained target image to a shape detector;
- and
- a shape detector, operatively coupled to said camera, said shape detector extracting a shape from the obtained target image based on movement candidate areas and image feature information extracted through an image difference of temporally-consecutive frames among an image sequence transmitted from the image input unit.
