USING CONTEXTUAL AND SPATIAL AWARENESS TO IMPROVE REMOTE DESKTOP IMAGING FIDELITY

摘要

Image data representing a desktop image for a client device that is accessing the desktop remotely is compressed according to a method that preserves image fidelity in selected non-text regions. The method, which is carried out in a remote server, includes the steps of generating image data for the remote desktop image and analyzing different regions of the remote desktop image, identifying those regions of the remote desktop image that are text regions, selecting non-text regions of the remote desktop image for lossless compression based on a spatial relationship between the non-text regions and the text regions, compressing the image data using a lossless compression protocol for a portion of the image data corresponding to the selected non-text regions, and transmitting the compressed image data to the client device.

主权项

1. A method of generating compressed data representing a remote desktop image, for a client device, comprising:
generating image data for a remote desktop image and analyzing different regions of the remote desktop image; identifying those regions of the remote desktop image that are text regions; selecting non-text regions of the remote desktop image based on a spatial relationship between the non-text regions and the text regions; compressing the image data using a first compression protocol for a first portion of the image data corresponding to the selected non-text regions and compressing the image data using a second compression protocol for a second portion of the image data not corresponding to the selected non-text regions, wherein the first compression protocol is less lossy than the first compression protocol; and transmitting the compressed image data to the client device.
