Depth maps captured by Kinect-like cameras are lack of depth data in some areas and suffer from heavy noise. These defects have negative impacts on practical applications. In order to enhance the depth maps, this paper proposes a new inpainting algorithm that extends the original fast marching method (FMM) to reconstruct unknown regions. The extended FMM incorporates an aligned color image as the...
The compass operator is a useful tool for the detection of edges, junctions and corners. However, it is time-consuming, especially when the circular window is large. In this paper, we propose a new compass operator based on the sampling scheme utilized in the DAISY descriptor. We first generalize the original DAISY for representing a variety of types of features. Then, the metric of measuring the...
Road detection is the most fundamental part of autonomous vehicles. Noises caused by shadows and vehicles on the road have a great negative impact on the road detection. Our method improves the performance under the noisy environment by taking advantage of color information to determine the road curvature. A novel geometrical method is proposed in this paper to select the most matched curvature. A...
