Patent number: 9031321Abstract: A content-adaptive edge and detail enhancement apparatus is described for image/video processing. Both 2D peaking and LTI/CTI are used in sharpening pictures. Image analysis is performed to generate a blending factor to control the use of the two peaking techniques. The strength or likelihood of edges or transitions is measured and such a strength or likelihood measurement will be transformed into the blending factor controlling the blending of the LTI/CTI and peaking outputs.Type: GrantFiled: May 23, 2014Date of Patent: May 12, 2015Assignee: Texas Instruments IncorporatedInventor: Fan Zhai

Publication number: 20120019727Abstract: A adaptive noise reduction filter is provided for reducing noise in a video signal. Each pixel in a portion of a video frame is evaluated to determine a likelihood L of impulse noise corruption to each pixel. A total number P of pixels in the video frame that have a likelihood of impulse noise corruption is determined. One of a plurality of spatial noise reduction filters is selected to use on the video frame based on the total number P and on the likelihood L of impulse noise corruption to a current pixel. A motion value for each of the pixels in the portion of the video frame may be determined and used to inhibit spatial noise reduction filtering of each pixel that has a low motion value.Type: ApplicationFiled: July 19, 2011Publication date: January 26, 2012Inventors: Fan Zhai, Weider P. Chang
