This paper presents a GPU-based stereo matching system with good performance in both accuracy and speed. The matching cost volume is initialized with an AD-Census measure, aggregated in dynamic cross-based regions, and updated in a scanline optimization framework to produce the disparity results. Various errors in the disparity results are effectively handled in a multi-step refinement process. Each...
This paper presents a novel adaptive tracking algorithm that fuses multiple cues based on feature uncertainty measurement in the particle filter framework. We first introduce a self-adaptive multi-cue fusion strategy, which overcomes the drawbacks of the traditional product fusion and sum fusion strategies. Furthermore, the proposed strategy effectively sharpens the distribution of the fused posterior...
To search corresponding points fast and accurately, a pair of stereo images must be rectified. A method is presented to rectify stereo pairs for uncalibrated cameras. The sampling of the original images is best preserved by penalizing minification and magnification effects. Experiments of image rectification show that this method can rectify stereo pairs accurately, and bring little image distortion.
