Paper Abstract

Motion detection is one of the basic operations in dynamic image analysis. In thermal image sequence processing, motion detection is a difficult problem. In this paper, we employ multi-scale optical flow methods to solve the problem. After analyzing the difficulties in detecting motions, multi-resolution framework is recognized as an useful approach for the process. Phase information has been demonstrated its robustness and stability in disparity and flow estimation. Velocity-tuned filtering integrates the multi-scale framework with the phase information. Using a bank of Gabor filters, image velocities, which form the flow field, are estimated with the output phase responses. Comparing with Lucas-Kanade pyramid method, our experiment shows that the approach could compute the optical flow more accurately, and it is effective for motion detection in infrared images.
