摘要： A method for encoding motion-compensated video data includes generating, for a current frame, a high-pass wavelet coefficient based on a function of pixels in a temporally adjacent frame. The operations are repeated for multiple pixels in an array of pixels in the current frame to form an array of high-pass wavelet coefficients. A low-pass wavelet coefficient is generated based on a function of the high-pass wavelet coefficients. A system for coding video data includes a temporal wavelet decomposition module decomposing a pixel into a high-pass coefficient by performing a discrete wavelet transform on the pixel, a function of pixels in a previous frame, and/or a function of pixels in a subsequent frame. The system includes a motion estimation module generating motion vectors associated with the pixels in the previous frame and in the subsequent frame.

摘要： Aspects of the subject matter described herein relate to image restoration for compressed images. In aspects, image restoration is accomplished by recovering spectral information from data corresponding to a compressed image. The spectral information is recovered using an algorithm to search through a solution space of possible solutions while constraints are imposed on the solution space to trim undesirable solutions from the space. An algorithm described herein may be iteratively applied to improve the quality of the recovered image.

摘要： An accelerated screen codec technique is described that provides a general screen compression framework, which, in one embodiment, is Graphics Processor Unit (GPU) friendly. In one embodiment, in order to compress screen data, blocks in a compound screen image containing both images and text are segmented into text blocks and pictorial blocks using a simple gradient-based procedure. The text and pictorial blocks are then compressed respectively via different compression techniques. Additionally, a GPU acceleration architecture of one embodiment of the accelerated screen codec technique provides a screen codec that maximally exploits a GPU's high parallelism and reduces the download bandwidth from GPU to Computer Processing Unit (CPU).

摘要： Techniques involve visually summarizing documents (e.g., search results, a collection of documents, etc.) using images which are visually representative of the documents for which the images represent. The images representing the documents may be external images obtained from sources other than the documents. The external images may be obtained from the sources other than the documents by performing a separate image based search using key phrases from the documents rather than extracting the images directly from within the documents themselves. Alternatively, an algorithm may be used to determine an image type, which may be chosen from a selection of external images, thumbnail images, or internal imaged taken directly from the collection of documents, that is suited to represent each document in the collection of documents. A snippet of the documents may be displayed along with the images which visually represent each of the documents.
摘要翻译：技术涉及使用视觉上代表图像所代表的文档的图像来可视地总结文档（例如，搜索结果，文档集合等）。表示文件的图像可以是从文档之外的源获得的外部图像。外部图像可以通过使用文档中的关键短语执行单独的图像搜索而不是从文档之外的来源获得，而不是直接从文档本身中提取图像。或者，可以使用算法来确定图像类型，其可以从外部图像的选择，缩略图图像或直接从文档集合中获取的内部图像中选择，其适于表示文档集合中的每个文档。文档的片段可以与可视地表示每个文档的图像一起显示。

摘要： A seamless bitstream switching schema is presented. The schema takes advantage of both the high coding efficiency of non-scalable bitstreams and the flexibility of scalable bitstreams. Small bandwidth fluctuations are accommodated by the scalability of the bitstreams, while large bandwidth fluctuations are tolerated by switching among scalable bitstreams. This seamless bitstream switching schema significantly improves the efficiency of scalable video coding over a broad range of bit rates.

摘要： Systems and methods for enhancement layer transcoding of fine-granular scalable video bitstreams are described. In one aspect, an enhancement layer bitstream is decoded from encoded video data. The encoded video data includes a base layer and one or more enhancement layers. The encoded video data is encoded according to a high HQRB (high quality reference bit-rate). Data throughput characteristics of a network coupled to a client computing device are determined. A new HQRB is calculated based on the data throughput characteristics. The decoded enhancement layer bitstream is then encoded based on the new HQRB to generate a transcoded enhancement layer for streaming to the client computing device. The base layer is not decoded for streaming to the client computing device.

摘要： Glitch-free media streaming is provided by a client computing device (“client”) independent of whether a remote computing device (“host”) associated with media content provides real-time media content streaming services. Specifically, the client computing device (“client”) provides a user with real-time media content streaming services by establishing multiple connections to the host to read respective portions of the media content by sending byte-range transport protocol requests to the host. As the reading operations progress, the client evaluates transmit rates over respective ones of the connections in view of a real-time media content playback rate to regulate data flow into a streaming media buffer and provide the user with a consistent high-quality (glitch-free) streaming media presentation.

摘要： Systems and methods provide object-based image inpainting. The object-based inpainting can recover part of a missing object or can synthesize visual objects that are entirely missing. In one implementation, an exemplary system generates a target visual object to be inpainted into an image, by geometrically matching key features with a model visual object that can be selected from the same or another image. Borders of the target object are refined through pixel-based contour deformation and textures for the target object are obtained either by pixel interpolation or by patch-based modeling of pre-existing texture in the image. Graph-cut segmentation rectifies image overlap as the target object is embedded in the image. Poisson editing filters visual seams, and edge filling completes visual gaps around the border of the target object.
摘要翻译：系统和方法提供基于对象的图像修复。基于对象的修复可以恢复缺少对象的一部分，或者可以合成完全缺失的可视对象。在一个实现中，示例性系统通过将关键特征与可以从相同图像或另一图像中选择的模型视觉对象几何匹配来生成要修饰成图像的目标视觉对象。通过基于像素的轮廓变形来改进目标对象的边界，通过像素插值或通过图像中预先存在的纹理的基于块的建模来获得目标对象的纹理。当目标物体嵌入在图像中时，图形分割会整理图像重叠。泊松编辑过滤视觉接缝，边缘填充完成目标物体边界周围的视觉间隙。
