摘要： Techniques for cropping images containing an occlusion are presented. A method for image editing is presented comprising, when an occlusion is detected in an original digital image, determining an area occupied by the occlusion, assigning importance scores to different content elements of the original digital image, defining a cropping window around an area of the original digital image that does not include the area occupied by the occlusion and that is based on the importance scores, and cropping the original digital image to the cropping window.

摘要： An encoder may include a luma transform, a transformer, and a chroma transform. The luma transform may determine a linear luminance value based upon a plurality of primary color values of a pixel. The transformer may generate a transformed luminance value based upon the linear luminance value and a plurality of transformed color values based upon corresponding more than one of the primary color values of the pixel. The chroma transform may determine a plurality of chroma values based upon corresponding plurality of transformed color values and the transformed luminance value of the pixel.

摘要： Video object and keypoint location detection techniques are presented. The system includes a detection system for generation locations of an object's keypoints along with probabilities associated with the locations, and a stability system for stabilizing keypoint locations of the detected objects. In some aspects, the generated probabilities are two-dimensional array correspond locations within input images, and stability system fits the generated probabilities to a two-dimensional probability distribution function.

摘要： In an example method, a system accesses first input data and a machine learning architecture. The machine learning architecture includes a first module having a first neural network, a second module having a second neural network, and a third module having a third neural network. The system generates a first feature set representing a first portion of the first input data using the first neural network, and a second feature set representing a second portion of the first input data using the second neural network. The system generates, using the third neural network, first output data based on the first feature set and the second feature set.

摘要： A scalable coding system codes video as a base layer representation and an enhancement layer representation. A base layer coder may code an LDR representation of a source video. A predictor may predict an HDR representation of the source video from the coded base layer data. A comparator may generate prediction residuals which represent a difference between an HDR representation of the source video and the predicted HDR representation of the source video. A quantizer may quantize the residuals down to an LDR representation. An enhancement layer coder may code the LDR residuals. In other scalable coding systems, the enhancement layer coder may code LDR-converted HDR video directly.

摘要： A method for processing media assets includes, given a first media asset, deriving characteristics from the first media asset, searching for other media assets having characteristics that correlate to the characteristics of the first media asset, when a match is found, deriving content corrections for the first media asset or a matching media asset from the other of the first media asset or the matching media asset, and correcting content of the first media asset or the matching media asset based on the content corrections.

摘要： A video coding server may code a common video sequence into a plurality of coded data streams, each coded data stream representing the video sequence coded using coding parameters tailored for a respective transmission bit rate. The coding may cause a set of transmission units from among the coded data streams to include coded video data from a common point of the video sequence, and a first coded frame of each transmission unit of the set to be a synchronization frame. A manifest file may be built representing an index of transmission units of the respective coded data streams. The coded data streams and manifest file may be stored by the server for delivery to a client device. During download and decode, the chunks may be decoded efficiently even when switching among streams because the first frame in each chunk is a synchronization frame.
