摘要： A method of encoding a local time base embedded in the compressed data is disclosed. The local time base is encoded in two parts. The first part has a modulo time base that indicates the specific interval in the reference time base and the second part has a time base increment relative to the reference time. Two forms of time base increment is used to allow for the possibility of different encoding order and displaying order. A mechanism for the synchronization of multiple compressed streams with local time base is also described. A time base offset mechanism is also used to allow finer granularity synchronization of the multiple compressed streams.

摘要： A video signal decoding apparatus according to the present invention includes a decoding unit for applying a variable length and run-length decoding to a compressed video signal to reconstruct blocks of quantized coefficients. An inverse quantizer is provided for inverse quantizing blocks of reconstructed quantized coefficients. An inverse DCT transforms the inverse quantized blocks of reconstructed quantized coefficients to produce a decoded block. An edge block detector determines whether decoded blocks are classified as an edge block. An adaptive edge enhancement filter removes the distortion in the decoded blocks when the edge block detector classifies decoded blocks as edge blocks. Thus, the video signal is decoded from the encoded video signal.

摘要： The present invention provides an image recognition apparatus with enhanced performance and robustness.In an image recognition apparatus 1, an image classification information accumulating unit 20 stores therein feature information defining visual features of various objects obtained through a learning process. For classification of input images, an image feature obtaining unit 18 extracts descriptors indicating features from each input image, image vocabularies corresponding to the descriptors are voted, and a classifying unit 19 calculates existence probabilities of one or more candidate objects, based on the result of the voting. According to the existence probabilities, objects contained in the image is identified. Through the calculation, the existence probabilities are adjusted by an exclusive classifier, based on exclusive relationship information defining exclusive object sets each containing different objects (object labels) predicted not to coexist in a same image.

摘要： A method and apparatus for motion blur and ghosting prevention in imaging system is presented. A residue image is computed by performing spatial-temporal filter with a set of absolute image difference of image pairs from input images. A noise adaptive pixel threshold is computed for every pixel based on noise statistics of image sensor. The residue image and the noise adaptive pixel threshold are used to create a motion masking map. The motion masking map is used to represent motion and non-motion pixels in pixels merging. The pixels merging step is performed to generate an output image by considering the motion pixels where the motion pixels are performed separately. The resulting output image having no or less motion blur and ghosting artifacts can be obtained, even the input images having different degree of motion blur between each of the image, while the complexity is low. It is preferred that the current invention is applied in the Bayer raw domain. The benefit is reduced computation and memory because only 1 color component is processed for each pixel. Another benefit is higher signal fidelity because processing in the Bayer raw domain is unaffected by demosaicing artifacts, especially along edges. However, the current invention can also be applied in RGB domain.
摘要翻译：提出了一种成像系统中运动模糊和重影防止的方法和装置。通过执行具有来自输入图像的图像对的一组绝对图像差异的空间 - 时间滤波来计算残差图像。基于图像传感器的噪声统计，为每个像素计算噪声自适应像素阈值。残差图像和噪声自适应像素阈值用于创建运动掩蔽图。运动屏蔽图用于表示像素合并中的运动和非运动像素。执行像素合并步骤，通过考虑分别执行运动像素的运动像素来生成输出图像。即使在复杂度低的情况下，甚至在每个图像之间具有不同的运动模糊度的输入图像也可以获得没有或更少的运动模糊和重影假象的结果输出图像。本发明优选应用于拜耳原始领域。该优点是减少了计算和存储器，因为每个像素只处理1个颜色分量。另一个好处是更高的信号保真度，因为拜耳原始域中的处理不受去马赛克伪像的影响，特别是沿着边缘。然而，本发明也可以应用于RGB域。
