Patent number: 9398314Abstract: Architecture for enhancing the compression (e.g., luma, chroma) of a video signal and improving the perceptual quality of the video compression schemes. The architecture operates to reshape the normal multimodal energy distribution of the input video signal to a new energy distribution. In the context of luma, the algorithm maps the black and white (or contrast) information of a picture to a new energy distribution. For example, the contrast can be enhanced in the middle range of the luma spectrum, thereby improving the contrast between a light foreground object and a dark background. At the same time, the algorithm reduces the bit-rate requirements at a particular quantization step size. The algorithm can be utilized also in post-processing to improve the quality of decoded video.Type: GrantFiled: February 5, 2008Date of Patent: July 19, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Walid Ali, Shankar Regunathan, Guo-Wei Shieh, Bruce Lin, Bharath Siravara, Ce Wang

Publication number: 20150358922Abstract: Disclosed is a method and a system for switching pre-distortion coefficients, which is used to solve the problem of interference with neighbor cells due to the inferior pre-distortion coefficients. The method comprises: presetting a primary table and a standby table, wherein the primary table stores default pre-distortion coefficients and the standby table stores updated pre-distortion coefficients; when a data source of a pre-distortion processor adopts the standby table, adopting the updated pre-distortion coefficients to perform parameter output processing to acquire pre-distortion parameters, and conveying the pre-distortion parameters and an input signal to the pre-distortion processor to process to acquire pre-distortion signals; conveying the pre-distortion signals through various signal processors to acquire a first signal, and determining the power data of the first signal; and based on the comparing result of the power data of the first signal and a setting range, there are different actions.Type: ApplicationFiled: December 30, 2013Publication date: December 10, 2015Applicant: DATANG MOBILE COMMUNICATIONS EQUIPMENT CO., LTDInventors: Jun XIONG, Tao DUAN, Huarong SUN, Peng XIAO, Ce WANG, Jieli WANG

Patent number: 8964829Abstract: Techniques to perform fast motion estimation are described. An apparatus may comprise a motion estimator operative to receive as input a current frame and a reference frame from a digital video sequence. The motion estimator may generate and output a motion vector. The motion vector may represent a change in position between a current block of the current frame and a matching reference block of the reference frame. The motion estimator may utilize an enhanced block matching technique to perform block matching based on stationary and spatially proximate blocks. Other embodiments are described and claimed.Type: GrantFiled: December 21, 2012Date of Patent: February 24, 2015Assignee: Microsoft CorporationInventors: Ce Wang, Walid Ali
