  • METHOD AND SYSTEM FOR IMPROVED DISPLAY OF SAMPLED DATA DIFFERENCES
    Publication number: 20100182334
    Abstract: A method of comparing a first raster to a second raster includes determining, for pairs of corresponding regions (for example, individual pixels) of the first raster and second raster, a comparison value between the corresponding regions of the first and second raster. For each comparison value, a color code is assigned based on a value of the comparison value. A comparison raster is generated from the color-coded comparison values. The comparison raster is presented to a reviewer.
