摘要： A method for converting between relatively close field rates of perhaps 60 Hz and 59.94 Hz, monitors the phase difference between input and output field rates. Initially, output fields are created by synchronizing input fields. As the measured phase passes a threshold, the method switches to interpolation mode for a short, fixed interval and then returns to synchronization. The method offers much of the sharpness associated with simple synchronization but avoids the visible discontinuities of field drops or repeats.

摘要： A method of and apparatus for image analysis for picture loss detection in fields or frames in video or film content makes use of different correlation characteristics of picture images and non-picture images to detect picture loss. A measure of self correlation of a plurality of image data samples, and a measure of the correlation of the plurality of image data samples with a mean value are determined, and a positive detection of picture loss is based on a comparison between the two correlation measures.

摘要： A method of image segmentation using graph-theory techniques, in which pixels of an image are represented by the vertices of a graph. A minimum spanning tree is generated and edges of the tree are successively removed according to a morphological property to leave a spanning forest, trees of which correspond to segments of the image. Selection of edges for removal may depend on an energy function of a tree and on the energy function of trees created by removal of that edge.

摘要： A video noise reducer divides a signal into spatial frequency bands and derives both recursively and non-recursively filtered signals for each band. Both signals are processed non-linearly. These signals are combined in ways that vary between the bands to provide a noise signal and a detail signal. A clean video signal with all noise removed is used in the recursive loop. The output signal includes detail enhancement and may have a subjectively pleasant amount of noise added back.

摘要： This invention concerns a system for the distribution of films by electronic means, and in particular, for ensuring a director's intended rendition of the images is attained in differing viewing conditions and technologies. Thus master data enabling the luminance and chromaticity of every part of every frame as previously displayed in a first display environment to be determined may be modified to achieve a similar subjective effect in a second display environment, the modification depending for example on data characterizing the said second display environment.

摘要： This invention concerns the interpolation of new intermediate images within an existing set of related images, for example views of a scene captured at different times, such as a sequence of film frames or video fields, or views of a scene captured from different camera positions, either simultaneously or in a time sequence. Motion vectors established for pixels or regions in at least one existing image are used to shift those pixels or regions to the output position of the new image. The shifted pixels or regions are combined in dependence on a probability of accuracy measure for the respective motion vector. The probability of accuracy measure may be formed from displaced-field difference measurements. The occlusion of objects is determined and used in forming the probability of accuracy measure.
摘要翻译：本发明涉及现有的一组相关图像中的新的中间图像的插值，例如在不同时间捕获的场景的视图，例如胶片帧或视频场的序列，或者从不同的相机位置捕获的场景的视图，同时或按时间顺序。使用为至少一个现有图像中的像素或区域建立的运动矢量将这些像素或区域移动到新图像的输出位置。移位的像素或区域根据各个运动矢量的精度测量的概率来组合。精度测量的概率可以由位移场差测量形成。确定对象的遮挡并用于形成精度测量的概率。

摘要： The present invention relates to methods and apparatus for interpolation of images, and in a particular example to de-interlacing of video signals using spatial interpolation. The present invention discloses a method for measuring the slope of a picture portion in which picture gradients are calculated from said selected pixel values and the slope measurement being derived from said gradient values. The invention also discloses a method of spatial interpolation of an array of pixel values, in which interpolated values are dependent upon the measurement of the slope associated with said array. Non-integer slopes can easily be accommodated with the method of the invention.
