Figure 5From: HoughFeature, a novel method for assessing drug effects in three-color cDNA microarray experimentsIllustration of the Hough transform in data and parameter spaces. Points in the data space (left) correspond to lines in the parameter space (right). Points on a line in the data space produce lines that intersect at the same point in the parameter space, while random points in the data space produce random lines in the parameter space.Back to article page
