摘要
Systems, methods and computer-readable storage media are disclosed for accelerating bitmap remoting by extracting patterns from source bitmaps. A server takes a source image, and performs an edge-detection operation on it. From this edge-detected image, connected segments of the image are determined by executing multiple iterations of a small operation upon the image in parallel—for instance, by assigning each non-white pixel a unique value, then assigning each pixel the minimum value among itself and its neighbors until no pixel is assigned a new value in an iteration. Executing these operations in parallel greatly reduces the time required to identify the connected segments. When the segments are identified, they may be cached by the client so that they do not need to be re-sent to the client when re-encountered by the server.
