Abstract:
1. A method for communicating an image section between a first computer and a second computer, the first computer adapted for remotely coupling to the second computer via a network, the method comprising: determining an image type of an input pixel value based on an analysis of the image section, the image type selected from a list comprising text and picture; determining an error threshold based on the image type; determining, by the first computer, a color table comparison result for the input pixel value, the color table comparison result identifying one of (i) an indexed color value of a color table, the indexed color value within the error threshold of the input pixel value, or (ii) an absence in the color table of any color value within the error threshold of the input pixel value; generating, based on the color table comparison result, encoded data comprising one of a derivative of the input pixel value or an index for the indexed color value; communicating, to the second computer, the encoded data; updating the color table according to the color table comparison result; repeating the steps of determining the color table comparison result, generating the encoded data and communicating the encoded data to determine a communication bandwidth of the encoded data; and adjusting the error threshold based on the communication bandwidth.
