Abstract

Various algorithms based on unwrapping first the most-reliable pixels have been proposed. These were restricted to continuous path and were subject to troubles on defining an initial pixel. The technique proposed uses a reliability function that helps us to define starting points, it does not follow a continuous path to perform the unwrapping operation, and it uses a mask to pick out invalid pixels. The technique is explained with all the specifics and exemplify with some examples.
