摘要： In a computerized method, the three-dimensional structure of an object is recovered from a closed-loop sequence of two-dimensional images taken by a camera undergoing some arbitrary motion. In one type of motion, the camera is held fixed, while the object completes a full 360.degree. rotation about an arbitrary axis. Alternatively, the camera can make a complete rotation about the object. In the sequence of images, feature tracking points are selected using pair-wise image registration. Ellipses are fitted to the feature tracking points to estimate the tilt of the axis of rotation. A set of variables are set to fixed values while minimizing an image-based objective function to extract a set of first structure and motion parameters. Then the set of variables freed while minimizing of the objective function continues to extract a second set of structure and motion parameters that are substantially the same as the first set of structure and motion parameters.

摘要： Stereoscopic image display is described. In an embodiment, a location of the eye pupils of a viewer is determined and tracked. An image is displayed within a first focus for viewing with the left eye of the viewer, and the image is displayed within a second focus for viewing with the right eye of the viewer. A positional change of the eye pupils is tracked and a sequential image that corresponds to the positional change of the eye pupils is generated for stereoscopic viewing. In another embodiment, an image is displayed for stereoscopic viewing and a head position of a viewer relative to a center of the displayed image is determined. A positional change of the viewer's head is tracked, and a sequential image that corresponds to the positional change of the viewer's head is generated for stereoscopic viewing.

摘要： Described is a technology by which an image such as a stitched panorama is automatically cropped based upon predicted quality data with respect to filling missing pixels. The image may be completed, including by completing only those missing pixels that remain after cropping. Predicting quality data may be based on using restricted search spaces corresponding to the missing pixels. The crop is computed based upon the quality data, in which the crop is biased towards including original pixels and excluding predicted low quality pixels. Missing pixels are completed by using restricted search spaces to find replacement values for the missing pixels, and may use histogram matching for texture synthesis.

摘要： A “Blur Remover” provides various techniques for constructing deblurred images from a sequence of motion-blurred images such as a video sequence of a scene. Significantly, this deblurring is accomplished without requiring specialized side information or camera setups. In fact, the Blur Remover receives sequential images, such as a typical video stream captured using conventional digital video capture devices, and directly processes those images to generate or construct deblurred images for use in a variety of applications. No other input beyond the video stream is required for a variety of the embodiments enabled by the Blur Remover. More specifically, the Blur Remover uses joint global motion estimation and multi-frame deblurring with optional automatic video “duty cycle” estimation to construct deblurred images from video sequences for use in a variety of applications. Further, the automatically estimated video duty cycle is also separately usable in a variety of applications.

摘要： Tilt is reduced or eliminated in captured digital images. Edges in a first image are detected. Angles corresponding to the detected edges are determined. A dominant angle is selected from the determined angles. The first image is rotated according to the selected dominant angle to generate a second image. The second image is a de-tilted version of the first image.

摘要： A low light noise reduction mechanism may perform denoising prior to demosaicing, and may also use parameters determined during the denoising operation for performing demosaicing. The denoising operation may attempt to find several patches of an image that are similar to a first patch, and use a weighted average based on similarity to determine an appropriate value for denoising a raw digital image. The same weighted average and similar patches may be used for demosaicing the same image after the denoising operation.

摘要： A system is described for reducing artifacts produced by a rolling shutter capture technique in the presence of high-frequency motion, e.g., produced by large accelerations or jitter. The system operates by computing low-frequency information based on the motion of points from one frame to the next. The system then uses the low-frequency information to infer the high-frequency motion, e.g., by treating the low-frequency information as known integrals of the unknown underlying high-frequency information. The system then uses the high-frequency information to reduce the presence of artifacts. In effect, the correction aims to re-render video information as though all the pixels in each frame were imaged at the same time using a global shutter technique. An auto-calibration module can estimate the value of a capture parameter, which relates to a time interval between the capture of two subsequent rows of video information.
摘要翻译：描述了一种用于在存在高频运动（例如由大的加速度或抖动产生的）的情况下减少由快门拍摄技术产生的假象的系统。该系统通过基于从一帧到下一帧的点的运动来计算低频信息来进行操作。然后，系统使用低频信息来推断高频运动，例如通过将低频信息作为未知底层高频信息的已知积分来处理。然后，系统使用高频信息来减少伪像的存在。实际上，校正旨在重新渲染视频信息，就像使用全局快门技术同时成像每个帧中的所有像素一样。自动校准模块可以估计捕获参数的值，其涉及捕获两个后续行的视频信息之间的时间间隔。

摘要： A process for compressing and decompressing non-keyframes in sequential sets of contemporaneous video frames making up multiple video streams where the video frames in a set depict substantially the same scene from different viewpoints. Each set of contemporaneous video frames has a plurality frames designated as keyframes with the remaining being non-keyframes. In one embodiment, the non-keyframes are compressed using a multi-directional spatial prediction technique. In another embodiment, the non-keyframes of each set of contemporaneous video frames are compressed using a combined chaining and spatial prediction compression technique. The spatial prediction compression technique employed can be a single direction technique where just one reference frame, and so one chain, is used to predict each non-keyframe, or it can be a multi-directional technique where two or more reference frames, and so chains, are used to predict each non-keyframe.
