摘要： An LDPC decoder, applicable to LDPC codes including codes where check nodes within the same group are connected to a common bit node, successively processes groups of check nodes in a particular iteration, including updating bit nodes in that same iteration responsive to messages generated in response to processing a group of check nodes. Within an iteration, the LDPC decoder may also track the number of unresolved parity check equations, and cease iterating or output to an outer block decoder if that number reaches a local minima or standard minimum, falls below a predetermined threshold, or its rate of change falls below a predetermined threshold, indicating a lack of convergence or false convergence condition. The LDPC decoder may also provide a feedback assist to a demodulator. Also, a novel memory configuration may store messages generated by the decoder in the course of check node processing. The decoder may also employ a novel method for generating check node to bit node messages through a prescribed series of pair-wise computations.

摘要： A method of reducing mosquito noise in a digital image. As mosquito noise is often most plainly visible in the “background” of an image (e.g., the sky or some other backdrop to objects within an image), the luminance value of the background of the image is first determined. Then, the luminances of the pixels of the image are compared against this “background luminance” to determine which should be considered as part of this background. The luminances of these background pixels are then averaged so as to smooth out the representation of the background, and reduce mosquito noise.
摘要翻译：减少数字图像中蚊子噪音的方法。由于蚊子噪音通常在图像的“背景”（例如，天空或图像内的对象的某些其他背景）中最明显可见，所以首先确定图像的背景的亮度值。然后，将图像的像素的亮度与该“背景亮度”进行比较，以确定应将其视为该背景的一部分。然后对这些背景像素的亮度进行平均，以平滑背景的表示，并减少蚊子的噪音。

摘要： Memory storage requirements for digital signal processing operations, for example, motion-compensated video scan rate conversion, that produce intermediate output data, which is then used as an input to the operation, are reduced by reordering operations and organizing memory allocations in a special manner to allow intermediate output at a particular execution time, to substantially share the same memory space as the intermediate output of a previous execution time. Such a reduction in the amount of memory required for processing operations advantageously reduces cost and power consumption.
