Aerial robots are becoming popular among general public, and with the development of artificial intelligence (AI), there is a trend to equip aerial robots with a natural user interface (NUI). Hand/arm gestures are an intuitive way to communicate for humans, and various research works have focused on controlling an aerial robot with natural gestures. However, the techniques in this area are still far...
Image acquisition in a low light environment requires long exposure to achieve acceptable signal-to-noise ratio, which however causes blurry effect. This paper addresses this problem by using a sharp near-infrared (NIR) image when the environment has sufficient NIR light. We assume that an RGB and NIR image pair has a linear mapping in a local area and that the mapping function is valid for both the...
We address the problem of accurate and efficient alignment of 3D point clouds captured by an RGB-D (Kinect-style) camera from different viewpoints. Our approach introduces a new cost function for the iterative closest point (ICP) algorithm that balances the significance of structural and photometric features with dynamically adjusted weights to improve the error minimization process. We also enhance...
Due to improvements in display devices, the JPEG XR is designed for high dynamic range (HDR) and HDPhoto size. According to the simulation results, the JPEG XR is superior to the JPEG LS about 5% to 20% improvement in compression ratio.
