Abstract-This paper proposes method for gesture recognition by two hands. In this research stereo camera was used to calculate depth map of the frame. Based on depth information precise tracking of the hands was applied. Depth map calculates in hardware level. Oversensitivity of camera to light generates horizontal noise. Especially appeared horizontal noise affects on tracking two hands located in same altitude. In this paper we suggest masking method to avoid horizontal noise in software level.Index Terms-Hand tracking, stereo camera, two hand gesture recognition, horizontal noise, dynamic programming, depth map.

A number of automotive electronics-safety, driver assistance, and infotainment devices-have been deployed in recent vehicles. This raises new challenges regarding in-vehicular network arbitration. A performance analysis of non-destructive arbitration has revealed a fairness issue. The arbitration prioritizes without collisions, despite multiple simultaneous transmissions; however, the performances of the highest priority node and the lowest priority node are very different. In this paper, an ID-rotation arbitration method to solve the arbitration-fairness problem is proposed. The proposed algorithm was applied to several engine control units (ECUs), including a controller area network (CAN) controller. Experimental results showed that the algorithm improved the fairness as well as the total throughput within a specific performance constraint.
