    摘要： Methods and systems for transcoding in a cloud computing platform are disclosed. According to an embodiment, a receiver receives an uploading file by one data block at a time, and stores the received data blocks in various storage modules. Small segment files are then generated when the size of the received data blocks is larger than a threshold. A transcoder transcodes the small segment files from one format such as a bit rate or a frame size to another while the receiver is still receiving a new data block. The transcoded small segment files may be stitched together to form a stitched file, which may be stored in a storage module to be downloaded through a content distribution network (CDN). The transcoded small segment files may be passed to streaming servers for streaming over a network while the receiver is still receiving a new data block of the uploading file.

    摘要： A system and method for region-of-interest-based bit-allocation scheme for video coding is provided. A method for encoding an image sequence of inter-frames and intra-frames includes grouping the inter-frames and the intra-frames in at least one group of pictures (GOP), and performing a frame-level bit-allocation to inter-frames and the intra-frames in the GOP. For each frame of the inter-frames and the intra-frames in the GOP, the method also includes partitioning the frame into a plurality of macroblocks, identifying macroblocks in the plurality of macroblocks as having regions of interest (ROI), and performing a macroblock level bit-allocation for the frame based on macroblocks identified as having ROI. The method further includes encoding the image sequence based on the bit-allocations, thereby producing an encoded image sequence, and outputting the encoded image sequence.

    摘要： An embodiment of a system and method that inserts a virtual image into a sequence of video frames. The method includes capturing geometric characteristics of the sequence of video frames, employing the captured geometric characteristics to define an area of the video frames for insertion of a virtual image, registering a video camera to the captured geometric characteristics, identifying features in the sequence of video frames to identify the defined area of video frames for insertion of the virtual image, and inserting the virtual image in the defined area. Vanishing points are estimated to determine the geometric characteristics, and the virtual image is blended with the area of video frames prior to inserting the virtual image in the defined area.
