摘要： A method of enhancing the perceived sharpness of an image by controlling a spatial interpolation process. A pixel value spatial gradient measure is formed and used to generate a map of modified pixel positions. In this map, the pixel spacing is reduced when the gradient measure is high. By using this map of modified pixel positions to control an otherwise conventional interpolation process, an output image is formed having a perceived sharpness which is greater than that of the unmodified output of the interpolation process.

摘要： Resampling a spatially sampled attribute of an image, for example up- or down-conversion, in which contributions to a symmetrical FIR resampling filter from positions outside the image—that is to say where the filter aperture extends beyond an image edge—are obtained by copying values from positions inside the image. This can conveniently be done by modifying filter coefficients.

摘要： The temporal sampling pattern of a sequence of images that represents a moving scene is classified into classes of temporal sampling patterns including “film”, “video” and “still”. Pixels in each image in the said sequence are classified according to the relationship between signed inter-image pixel-value differences f1 and f2 between that image and, respectively, the preceding and succeeding images in the sequence. An initial classification for each pixel may be refined in accordance with the relative numbers of pixels of the image initially classified into each class.
摘要翻译：表示移动场景的图像序列的时间采样图案被分类为包括“电影”，“视频”和“静止”的时间采样模式的类别。所述序列中的每个图像中的像素根据该图像之间的有符号的图像间像素值差f1和f2与序列中的先前和后续图像之间的关系进行分类。可以根据最初被分类到每个类中的图像的像素的相对数目来对每个像素进行初始分类。

摘要： The invention relates to the analysis of characteristics of audio and/or video signals for the generation of audio-visual content signatures. To determine an audio signature a region of interest for example of high entropy—is identified in audio signature data. This region of interest is then provided as an audio signature with offset information. A video signature is also provided.

摘要： In for example the assignment of motion vectors, an array of pixel-to-pixel dissimilarity values is analysed to identify a pixel which has a low pixel-to-pixel dissimilarity value and which has neighbouring pixels which have a low pixel-to-pixel dissimilarity value. The pixel-to-pixel dissimilarity values are filtered with a filter aperture decomposed into two or more sectors with partial filters applied respectively to each sector. Outputs of the partial filters are combining by a non-linear operation, for example taking the minimum from diametrically opposed sectors.

摘要： To modify the aspect ratio of images in a video sequence, a measure of image energy is provided at or around each pixel, for example by taking differences between adjacent pixels. A minimum energy path of contiguous pixels is then identified which extends across the image from one edge to another, for example vertically if the width of the picture is to be modified. Information concerning the location of a path in one image is used in the identification of a path in the next image, for example by biasing the energy measure of the path. The aspect ratio of each image is then modified by removing or by replicating the minimum energy path of contiguous pixels.
摘要翻译：为了修改视频序列中的图像的纵横比，例如通过取得相邻像素之间的差异，在每个像素处或周围提供图像能量的度量。然后识别连续像素的最小能量路径，其延伸穿过图像从一个边缘到另一个边缘，例如如果要修改图像的宽度，则是垂直的。关于一个图像中的路径的位置的信息用于识别下一图像中的路径，例如通过偏置路径的能量测量。然后通过去除或通过复制连续像素的最小能量路径来修改每个图像的纵横比。

摘要： The invention concerns image processing and, in particular, the processing of picture attribute fields for an image. A method of obtaining a new picture attribute field of an image is disclosed in which a picture attribute value at one position is allocated to a new position in the image in dependence upon the value of a parameter, such as luminance data, at the original position and at the new position and/or in dependence on the distance between the original position and the new position. The invention may be used to process picture attribute fields comprising: motion vectors; motion vector confidence; segment labels; depth labels; texture labels.

摘要： Systems and methods of rendering a motion image. A television signal is modified through a sine wave motion judder component to introduce intentional motion judder which can replicate the appearance of cinematic projection. To present 24 frames per second film via a 60 Hz television system with the “look” of a 72 Hz cinematic projector, a judder oscillator is set to generate a 24 Hz sinewave having a peak amplitude equal to 38.5% of the time difference between 24 Hz frames. The motion-judder component may periodically reverse the apparent direction of motion.
