Abstract
An image processing method is described that allows a user to manipulate regions of interest (ROIs) in a mask based image. The user defines a stretch vector for example by ‘clicking and dragging’ a mouse pointer and an algorithm deforms the ROI according to a roll-off function that avoids the non-smooth edge effects seen in prior art techniques such as paintbrushes.
