摘要： Systems and methods are disclosed for determining the perceptibility of noise in a block of images and/or video. The systems and methods may compute a mask value for the block using a block masking generator. The mask value may indicate the perceptibility of noise in the block. The mask value may be computed using a normalized activity value and/or a texture value for the block. The normalized activity value may indicate the relative activity in the block as compared to the activity in the image and/or video. The texture value may indicate the strength and/or number of edges in the block.

摘要： An apparatus and method for coding block boundary detection using interpolated autocorrelation is disclosed. Input video frames are processed to obtain a binary map of possible block boundary pixels including original and rescaled block boundaries. The boundary pixel map is converted to a boundary histogram. Then interpolated autocorrelation is applied to the boundary histogram to detect the block size and block size offset. The interpolated autocorrelation handles both integer sizes and non-integer sizes. A confidence measure is also determined that reflects the accuracy of the detection result. The output for the current video frame is also post processed with information from previous frames to provide better temporal stability.

摘要： In a process for enhancing contrast of an image having pixels in different brightness intensities, a histogram in discrete bins is generated. Each bin represents a pixel population of at least one pixel brightness intensity. A peak and a peak region of the histogram is then identified, wherein the peak region is a range of discrete bins around the peak. An average pixel population within the peak region is computed, and the pixel populations of the discrete bins within the peak region that exceeds the average pixel population are distributed. A transfer curve for mapping onto the image is then generated. The process can be used in an image processor for enhancing contrast of an image having pixel. Still further, a display having a receiver and a screen can include the foregoing image processor.

摘要： A system, apparatus and method are disclosed for separating a current frame of a composite video signal into a luminance signal and a chroma signal. A relative chroma correlation value is generated using a plurality of lines of the current frame. A weighted sum of inter-line pixel differences of the current frame is generated using the relative chroma correlation value. A frame difference signal is generated by subtracting a previous frame of the composite video signal from the current frame. A detected motion signal is generated that corresponds to motion detected in the current frame. The weighted sum of inter-line pixel differences, the frame difference signal, and the detected motion signal are combined to generate the chroma signal. The chroma signal is subtracted from the current frame to generate the luminance signal.
