In this paper, we propose a three-dimensional gesture interactive system design of home automation for physically handicapped people. In order to provide a convenient and comfortable environment, we design a finger and hand gesture user interface for physically handicapped people based on stereo cameras to achieve remote control and gesture recognition system. We use stereo camera to capture stereo image and calculate disparity map and depth map for supplying physically handicapped people a real-time interface based on hand gesture and finger action. The system can achieve 93% accuracy of eight direction function, 93.75% accuracy of zoom function, and 90% accuracy of click function. The experimental results prove the efficiency of the proposed system.

In this paper, depth map estimation circuit design based on structured light is proposed, wherein a projection light source and an image sensor are utilized in combination to achieve a depth map estimation chip, an accurate, low complex circuit is presented to measure the depth value of an object, and it is applied to 3-D television through depth imagebased rendering technology to implement a multiview image display system. The chip that integrates image preprocessing, object segmentation, edge detection, and depth map quantization algorithms performs depth map estimation of objects accurately and quickly. Besides, the effect of human visual sensing effect is taken into consideration and the presented chip achieves a depth map quantified according to the nonlinear depth value in compliance with human visual system. Measurement results show that the chip that is verified using a Taiwan Semiconductor Manufacturing Company 0.18-µm 1P6M CMOS process operates at 83.3 MHz with 19 845 gate counts and performs real time depth map estimation. Index Terms-3-D television (3-DTV), depth map estimation, structured light.

An engineering change orders design using multiple variable linear programming for VLSI design is presented in this paper. This approach addresses the main issues of resource between spare cells and target cells. We adopt linear programming technique to plan and balance the spare cells and target cells to meet the new specification according to logic transformation. The proposed method solves the related problem of resource for ECO problems and provides a well solution. The scheme shows new concept to manage the spare cells to meet possible target cells for ECO research.
