Latest Patents

One of her latest patents is titled "Video quality assessment with test video sequences." This invention introduces a test video sequence designed to measure quality loss in processed video. By inserting specific types of overhead video data into the test video sequence before processing, the measurement of quality loss during compression or other processing can be enhanced. The processed test video sequence can then be compared to the pre-processed version, allowing for improvements in the comparison operation. Padded areas, such as uniform-color frames, are strategically inserted to absorb quality loss and identify key points in the video clips. Additionally, a special color bar can be used to detect changes that need correction before comparing the video clips.

Another significant patent is the "In-service video quality measurement system utilizing an arbitrary bandwidth ancillary data channel." This apparatus measures the quality of video transmission or storage systems, even when the input and output may be spatially separated. It continuously extracts features from processed input and output video frames, communicating these features through an ancillary data channel of variable bandwidth. The system computes individual video quality parameters and calculates a composite video quality score, which is influenced by the bandwidth of the ancillary data channel.
