Systems and Methods for Motion Adaptive Filtering

Abstract: Methods and systems for motion adaptive filtering detect movement of text or areas of high spatial frequency in one frame to another frame of an image. When such movement is detected and meets a certain level or threshold, the subpixel rendering processing of such text or areas of high spatial frequency may be changed.

System and method of performing dot inversion with standard drivers and backplane on novel display panel layouts

Abstract: A system and method are disclosed for performing dot inversion with standard drivers and backplane on novel display panel layouts. Suitable dot inversion schemes are implemented on a liquid crystal display having a panel and a driver circuit. The panel substantially comprises a subpixel repeating group, the group having a even number of subpixels across a first direction. The driver circuit comprises a set of drivers, coupled to the panel providing image data signals to the panel, the signals effecting substantially a dot inversion scheme to the panel. The drivers are also substantially connected to the columns of the panel in a sequence along the driver circuit wherein at least one driver is not connected to a column of the panel, and at least two subpixel regions of the panel having same colored subpixels in the two regions with substantially different polarities.

Real-time camera pose in a room

Abstract: Many applications of computer vision require camera pose in real-time. We present a new, fully mobile, purely vision-based tracking system that works indoors in a prepared room, using artificial landmarks. The main contributions of the paper are: improved pose accuracy by subpixel corner localization, high frame rates by CMOS image aquisition of small subwindows, and a novel sparse 3D model of the room for a spatial target representation and selection scheme which gains robustness.

Naked-eye 3D display system based on Unity 3D game engine

Abstract: The utility model proposes a naked-eye 3D display system based on a Unity 3D game engine. The system comprises a Shader which is programmed and operates on a GPU according to a subpixel projection matrix of a calculated view spot. The Shader comprises a top spot Shader and a segment Shader. A plurality of stereo cameras are built in Unity 3D software, and are arranged according to a certain structural position. Finally, a rendering chartlet outputted by each stereo camera is sampled and fused by the Shader, and an obtained composite image is outputted to a naked-eye 3D display screen, thereby achieving naked-eye 3D display.

Kolmogorov and Zabih's Graph Cuts Stereo Matching Algorithm

Abstract: Binocular stereovision estimates the three-dimensional shape of a scene from two photographs taken from different points of view. In rectified epipolar geometry, this is equivalent to a matching problem. This article describes a method proposed by Kolmogorov and Zabih in 2001, which puts forward an energy-based formulation. The aim is to minimize a four-term-energy. This energy is not convex and cannot be minimized except among a class of perturbations called expansion moves, in which case an exact minimization can be done with graph cuts techniques. One noteworthy feature of this method is that it handles occlusion: The algorithm detects points that cannot be matched with any point in the other image. In this method displacements are pixel accurate (no subpixel refinement).
