Abstract
Techniques are disclosed for acceleration techniques for improved image remoting. A rolling 2D hash of a first image sent to a client is computed. When the server has a second image to send to the client, it calculates a rolling 2D hash of the new image. It also calculates 'pivot points' for the images based on the rolling 2D hashes. Based on the pivot points, it determines possible matching hash windows between the two images that correspond to window moves or scrolls. Where a match is confirmed, it determines whether a 'larger' a larger matching rectangle exists between the two images. It then instructs the client to display the matching rectangle that exists in the first image that the client has in the appropriate location in the second image, thereby saving the bandwidth requirements to re-transmit it to the client.
