An image with good contrast has sharp differences between black and white, and this helps us to label ground truth data since we can find the edge of objects clearly.
However, the image we want to label on may have poor contrast. For example, medical image is a high dynamic range image in many cases, and intensity values tend to be limited to specific portion of the range.

This tool enable you to interactively adjust contrast and brightness for pixel labeling. You can adjust contrast and brightness by changing image window width and window center on separately launched figure window from Labeler App.
This tool can be used with imageLabeler, videoLabeler and groundTruthLabeler. Please see the header of adjustContrast.m to learn how to use this tool.
