20120008051 | SYSTEM AND METHOD FOR SHOT CHANGE DETECTION IN A VIDEO SEQUENCE - A computer implemented method for automatically identifying shot changes in a video sequence in real-time or near-real-time is disclosed. Optical flow energy change differences between frames, sum-of-square differences between optical-flow-compensated frames, and hue histogram changes within frames are analyzed and stored in frame buffers. A feature vector formed from a combination of these measurements is compared to a feature vector formed from thresholds based on tunable recall and precision to declare the presence or absence of a shot change. | 01-12-2012 |
20120008672 | SYSTEM AND METHOD FOR TRANSMISSION, PROCESSING, AND RENDERING OF STEREOSCOPIC AND MULTI-VIEW IMAGES - A digital image processing system takes color plus Z channel data as input, preprocesses, decimates, and codes the Z channel in-band as digital watermark data embedded within the color data prior to encoding and transmission. A second digital image processing system receives, decodes, and extracts the decimated Z channel data before applying statistical regularization to restore a full-resolution Z channel prior to depth-image-based rendering. | 01-12-2012 |

20140241582 | DIGITAL PROCESSING METHOD AND SYSTEM FOR DETERMINATION OF OBJECT OCCLUSION IN AN IMAGE SEQUENCE - A method and system for occlusion region detection and measurement between a pair of images are disclosed. A processing device receives a first image and a second image. The processing device estimates a field of motion vectors between the first image and the second image. The processing device motion compensates the first image toward the second image to obtain a motion-compensated image. The processing device compares a plurality of pixel values of the motion-compensated image to a plurality of pixels of the first image to estimate an error field. The processing device inputs the error field to a weighted error cost function to obtain an initial occlusion map. The processing device regularizes the initial occlusion map to obtain a regularized occlusion map. | 08-28-2014 |
