Latest Patents

Chang's latest patents include a method for segmenting and estimating a moving object motion. This method is designed for use in an object-oriented analysis-synthesis coder, allowing for the segmentation of an image of a current frame into moving objects. It describes each motion of the moving objects with a set of motion parameters. The process involves several steps, including comparing the current frame with a preceding frame to detect a motion vector field, evaluating the homogeneity of window blocks, and determining revised values for motion parameters until a set of final values is established. Another patent focuses on a multi-stage segmentation method for segmenting an image signal into moving objects and describing their motion parameters. This method employs a series of comparisons and segmentations using various patch models to achieve accurate motion estimation.
