Figure 4From: HoughFeature, a novel method for assessing drug effects in three-color cDNA microarray experimentsThe peak points corresponding to the 15 detected lines in the polar parameter space obtained using the HoughFeature algorithm. The up-regulated genes are shown in (a) and the curve intersection regions are zoomed in and shown in (b). The down-regulated genes are shown in (c) and the curve intersection regions are zoomed in and shown in (d).Back to article page
