Title: Yao Wang: Innovator in Video Quality Assessment and Signal Reconstruction
Introduction
Yao Wang is a prominent inventor based in Brooklyn, NY, known for his contributions to video quality assessment and signal reconstruction technologies. With a total of 2 patents, Wang has made significant strides in improving the quality of video transmission and signal processing.
Latest Patents
Wang's latest patents include a "System and method for estimating quality of video with frame freezing artifacts." This innovative method assesses the quality of transmitted video packet signals that suffer from packet loss and delay, which can lead to freeze events and jerkiness during video playback. The system compares video frames to identify freeze events, extracts features from these locations, and utilizes a neural network to map these features into a video quality score. This score effectively evaluates the impact of irregular frame freezes on video quality.
Another notable patent is the "Method and apparatus for signal reconstruction." This method addresses the challenge of reconstructing incomplete signals in sub-band transmission systems. By formulating an error function, Wang's approach minimizes the error between interpolated sub-band signals and the original signals, ensuring optimal signal reconstruction and reducing degradation from signal loss.
Career Highlights
Throughout his career, Yao Wang has worked with several notable companies, including U S West Advanced Technologies, Inc. and Oovoo LLC. His experience in these organizations has contributed to his expertise in video technology and signal processing.
Collaborations
Wang has collaborated with esteemed colleagues such as V Ramamoorthy and Chang Feng, further enhancing his innovative work in the field.
