摘要： A method of processing an image signal comprising image and depth information is provided. The method is configured to perform segmentation on an image based on depth/disparity information present in the image signal comprising said image, and subsequently inpaint background for correction of the errors in the image around the foreground objects into a region that extends beyond the segment boundary of the foreground object and/or inpaint foreground for correction of errors in the image into a region that extends inside the segment boundary of the foreground object. In this way compression and other artifacts may be reduced.

摘要： A method of image analysis, includes: obtaining a sequence (37;51) of images, each represented by pixel data; performing a vision-based analysis on at least one of the sequence (37;51) of images to obtain data for classifying a state of a subject represented in the images;—determining at least one value of a physiological parameter of a living being represented in at least some of the sequence (37;51) of images; and classifying a state of the subject using the data obtained with the vision-based analysis and the at least one value of the physiological parameter. The at least one value of the physiological parameter is determined through analysis of image data from the same sequence (37;51) of images from which the at least one image on which the vision-based analysis is performed is taken. A method of enabling remote photoplethysmographic analysis includes: obtaining a sequence (37;51) of images from at least one camera (3), each represented by pixel data representative of reflected ambient light in at least a limited range of wavelengths; and, for at least one measurement zone (41), providing a signal representative of at least variations in a time-varying value of a combination of pixel values at least a number of image points in the measurement zone (41) for use in determining at least one value of a physiological parameter. At least part of a selected subject represented in the sequence (37;51) of images is tracked, and a directable light source (4) illuminating at least part of the selected subject is controlled.

摘要： The present invention provides a method of distributing content to a plurality of clients. The method on a server begins with accessing content to be distributed to a plurality of clients and identifying a first type of content to be distributed as crucial content and identifying a second type of content to be distributed as non-crucial content. The crucial content is any content required to properly render, after a decryption process, the content. The non-crucial content is all the other content to be distributed. The crucial content is encrypted with a first encrypting key which is unique to each of the plurality of clients. The crucial content which has been encrypted is transmitted. The non-crucial content is transmitted to the plurality of clients.
摘要翻译：本发明提供一种向多个客户端分发内容的方法。服务器上的方法开始于访问要分发到多个客户端的内容，并且识别要作为关键内容分发的第一类型的内容，并且识别要作为非关键内容分发的第二类型的内容。关键内容是在解密过程之后正确呈现内容所需的任何内容。非关键内容是要分发的其他内容。关键内容使用对于多个客户端中的每一个唯一的第一加密密钥进行加密。发送已经加密的关键内容。非关键内容被发送到多个客户端。
