The DIBR technique generates a 3-D perception through a 2-D color and a depth map sequences. Compressing depth map sequence is necessary for storage and transmission considerations. However, the tradeoff between bit rate reduction and quality degradation from compression should be addressed. We propose a bit rate-saving intra coding scheme which modifies, prior to compression, each depth map to minimize...
This paper proposed a bi-directional people-flow counting system with Kinect. It can also be applied to multi-flow to correspond with the demand for the practical application. Firstly, we set the Kinect above the doorway to capture the situation of pedestrian flow. Then this system detects people in the covering area using the depth image information from Kinect system. And we do the morphological...
In this paper, a new digital image stabilization involving multiple objects motion detection based on block-based Hough transform (HT) is presented. The line edges in a pair of edge blocks, where one is from current frame and the other is from previous frame are aligned to generate potential motion vectors to have votes on parameter voting matrix H using modified HT. The parameter voting matrix H...
In this paper we present a instant and real-time mobile vehicle license plate recognition system in an open environment. Using a nonfixed video camera installed in the car, the system tries to capture the image of the car in front and to process instant vehicle license plate detection and recognition. Relying on the instant vehicle body recognition, the system can detect and locate the vehicle license...
In this paper, we use two visible laser points as the measuring ruler for automatically adjusting measurement. It is a breakthrough compared with using double CCD cameras or the measuring method of setting up reference at measuring points. By using a single image, we can realize the non-contact distance measurement. The measuring principle is to produce two bright projection spots on the measuring...
