摘要： An advanced media preview unit includes a preview generation processor 300 that extracts a number of preview frames and generates a preview media file in a preview generation process 300. The preview frames are saved in a layered data structure. In addition, the preview frames may be scaled to a lower resolution so that the preview file formed by the preview frames is reduced in size. The preview media file is delivered to a user through a preview delivery process 302. For example, a delivery scheduling scheme delivers the preview frames at selected time points to minimize startup delay and playback jitter. At a user side, through a plug-in module, the advanced media preview unit performs a preview rendering process 304.

摘要： In accordance with an embodiment, a method of authenticating images includes electronically receiving an anchor image and a query image, performing a feature point extraction of an anchor image, and performing a feature point extraction of a query image. The method also includes clustering feature points of the anchor image and feature points of the query image, where clustering includes determining matching feature points, determining outlier feature points, and excluding outlier feature points. Whether the anchor image is similar to the query image is determined based on a distance between the feature points of the anchor image and the feature points of the query image. If the anchor image is similar to the query image, possible tampered areas of the query image based on the outlier feature points are identified.

摘要： An image processing method can be performed on a video image that includes an initial frame and a plurality of subsequent frames. An object is located within the initial frame of the video image and a histogram related to the object is generated (object initialization). A foreground map that includes the object is also generated (foreground map). For each subsequent frame, a mean shift iteration is performed to adjust the location of the object within the current frame (mean shift iteration). The histogram related to the object and the foreground map can then be updated (histogram update).
