Abstract: An image processing system is disclosed which uses gain information from an input image to determine a threshold value used to filter the input image. The gain information is indicative of the amount of illumination of the input image and thus the noise level. The image processing system includes an image processor, a converter and a filter. The image processor receives and processes first image information into second image information and extracts the gain information from the first image information. The converter converts the gain information into a filter threshold, which is used by the filter to filter the second image information to provide filtered image information. The converter may include a lookup table storing noise characteristic estimates or the threshold values. The threshold values may further be based on subband size. The filter may be a wavelet-based transform denoising filter.

Abstract: Forming image information of image units (e.g. pixels) of a higher resolution by convoluting information of image units of a lower resolution with coefficients of a multiphase filter. The information of one set of higher resolution image units is formed by convoluting in a first direction the information of the lower resolution image units with a first set of four coefficients. The information of a second set of higher resolution image units is form by convoluting in the first direction the information of the lower resolution image units with a second set of four coefficients. Convolution may also be performed in a second direction with a set of four coefficients. In one example, the image information formed includes intensity information for each image unit.

Abstract: Sequential video data frames are encoded using cores including a first core and a second core. A first beginning frame is divided into slices. The first core is assigned to process a first slice. The second core is assigned to process a second slice. The first beginning frame is processed using the cores which results in a first ending frame in which the first slice was partitioned into a third slice and a fourth slice. The third slice was processed by the first core. The fourth slice and the second slice were processed by the second core. A second beginning frame, which immediately follows the first ending frame, is divided into a second plurality of slices. The first core is assigned to the third slice. The second core is assigned to a fifth slice which has a size equal to a sum of the second and fourth slices.

Abstract: A method of processing video information which includes receiving encoded video information including an encoded base layer frame and encoded enhanced layer frames for providing temporal scalability, decoding the encoded video information in display order, and using a decoded first enhanced layer frame as a reference frame for decoding a second enhanced layer frame for forward prediction. Processing the video information in display order and using a decoded enhanced layer frame as a reference frame for processing another enhanced layer frame for forward prediction reduces coding latency for achieving temporal scalability for low delay scalable video coding. The coding memory space may also be reduced as compared to bidirectional prediction coding since the number of reference frames used for coding may be reduced.

Abstract: A fast motion estimation system that determines a reference macroblock or sub-block combination within a reference frame for a current macroblock in a current frame includes a memory, a reference macroblock search circuit, a sub-block combination search circuit, and a comparator circuit. The reference macroblock search circuit determines a motion vector, multiple difference values, and a cost value for each macroblock within the reference frame according to a fast motion estimation search pattern, and stores the motion vector and the difference values in the memory. The sub-block combination search circuit searches the motion vector and the difference values in the memory for determining a corresponding one of multiple lowest cost sub-block combinations for each of multiple sub-block motion modes. The comparator circuit determines a lowest cost macroblock and selects from among the lowest cost macroblock and the lowest cost sub-block combinations to determine the reference macroblock.
