Abstract: Methods and systems for a regression-based learning model in image upscaling are disclosed. In one embodiment, a set of image patch pairs for each of a set of images is generated. Each of the image patch pairs contains a natural image and a corresponding downscaled lower-resolution image. A regression model based at least in part on the set of image patch pairs is defined. The regression model represents a gradient of a function of the downscaled lower-resolution image. An image is upscaled based at least in part on the regression model.

Abstract: A method for organizing individual collections of images or videos captured for the same event by different cameras into a master collection, wherein each individual collection forms a media stream in chronological order. A processor for extracting image features for each image or video of the media stream of each collection; constructing a graph based on the extracted features to link the images or videos from the two media streams; finding on the graph at least a pair of images or videos, each from one of the two media streams, that corresponds to correlated captured content; aligning the remaining images or videos in response to the aligned pair so that the all images or videos from the two media streams are aligned over a common timeline; and producing a master stream in chronological order of the event over a common timeline by merging the aligned individual.
Abstract translation: 一种用于将由不同相机拍摄的相同事件的图像或视频的各个集合组织成主集合的方法，其中每个单独集合以时间顺序形成媒体流。 一种用于为每个集合的媒体流的每个图像或视频提取图像特征的处理器; 基于提取的特征构建图表以链接来自两个媒体流的图像或视频; 在图上找到至少一对图像或视频，每个图像或视频各自来自两个媒体流之一，对应于相关的捕获的内容; 响应于对准的对对齐剩余的图像或视频，使得来自两个媒体流的所有图像或视频在公共时间线上对齐; 并通过合并对齐的个体在公共时间轴上按时间顺序生成主流。

Abstract: Methods and systems for denoising and artifact removal in image upscaling are disclosed. In one embodiment, a low frequency band image intermediate is obtained from an input image. An upsampled image intermediate is obtained from the input image by upsampling. A result image is estimated, based at least in part on the upsampled image intermediate, the low frequency band image intermediate, and the input image. The input image is of a smaller scale than the result image. The estimating the result image further includes eliminating from the result image noise that is present in the input image.
