ON GENERATING GROUND-TRUTH TIME-LAPSE IMAGE SEQUENCES AND FLOW FIELDS

Vladimír Ulman, Jan Hubený

Abstract

The availability of time-lapse image sequencies accompanied with appropriate ground-truth flow fields is crucial for quantitative evaluation of any optical flow computation method. Moreover, since these methods are often part of automatic object-tracking or motion-detection solutions used mainly in robotics and computer vision, an artificially generated high-fidelity test data is obviously needed. In this paper, we present a framework that allows for automatic generation of such image sequences based on real-world model image together with an artificial flow field. The framework benefits of a two-layered approach in which user-selected foreground is locally moved and inserted into an artificially generated background. The background is visually similar to the input real image while the foreground is extracted from it and so its fidelity is guaranteed. The framework is capable of generating 2D and 3D image sequences of arbitrary length. A brief discussion as well as an example of application in optical microscopy imaging is presented.
