ENHANCING MOTION PICTURES WITH ACCURATE MOTION INFORMATION

摘要

Methods and systems for digitally enhancing the characteristics of an image sequence including video and motion picture images are provided. Highly accurate motion information represented by trajectories are generated through analyzing available image frames in the image sequence. Some embodiments of the present invention relate to generating multiple layer trajectories from an image sequence. Certain aspects may be applicable to the enhancement of three-dimensional (3D) image sequences including 3D video and 3D motion pictures.

1. A method to enhance an image sequence, the method comprising:
receiving the image sequence with image frames; determining a decomposition feature for the image frames; computing feature connections for image pixels based on the decomposition feature; calculating at least one anchor trajectory based on at least one selected feature connection among the feature connections; determining a relationship of an image pixel with the at least one anchor trajectory; creating a new trajectory for an image pixel of decomposed image frames based on the at least one anchor trajectory and the relationship of the image pixel with the at least one anchor trajectory; defining at least one trajectory feature for the new trajectory and determining whether the at least one trajectory feature needs to be modified at a new trajectory intersection; refining the new trajectory intersection and producing a final trajectory; creating an enhanced image pixel by modifying a pixel image feature based on the final trajectory; creating an enhanced image sequence based on the enhanced image pixel; and outputting the enhanced image sequence.
