Quickly setting RGB or HSV values for color thresholding is a common problem in laboratory robotics. ColorThreshold.m allows you to load an image and interactively set either RGB or HSV thresholds. Call the function ColorThreshold('image_name'), select your Region Of Interest, then select and deselect pixels and watch the thresholded image and RGB/HSV scatter plots to fine tune your threshold filter. You can switch between HSV and RGB while the program is running, and can choose to split the Hue threshold (single color objects commonly have a wraparound in the Hue value). The update allows users to interactively tune their filters with slider bars and move the ROI.
