OFCat: An Extensible GUI-Driven Optical Flow Comparison Tool

摘要

OFCat is an extensible GUI-driven optical flow computation and analysis tool. The user can add their own image sequences, filtering, differentiating and optical flow techniques. OFCat can process both grayscale and color images. It implements a number of low-pass filtering and differentiating techniques. Many traditional optical flow extraction techniques are available, in addition to some novel color-based methods. Analysis of the recovered flow is performed using groundtruth analysis, image reconstruction and sparsity vs error analysis. Synthetic ground-truth can be created and used to create a test image sequence from a single image.
