Depth from Focus (DFF) is the one of the optical methods to estimate depth information. In this paper, we propose a new approach based on blur estimation to obtain depth map. The optimal focused points are selected by maximizing absolute values of deferences in blur signal. The proposed method provides more robust depth information.

We propose a background scene classification method robust to the influence of human regions. Conventional methods classify scene of an image by using image features extracted from entire region in the image. Therefore, in these methods, the influence of the human region such as color of the skin and the clothes reduces classification accuracy of the background scene. Our method classifies background scene of an image by using image features extracted from only background region except detected human regions. The experimental results show that the proposed method improves average of the rate at the balance point between recall rate and precision rate in almost all background scenes compared to the conventional method.

We propose an automatic airbag system helping evacuating swimmer who is motionless or spent abnormally long time underwater. The system is composed of a customized waist airbag and Smartphone equipped with pressure sensor and accelerometer. The Smartphone application will try to define accurately the position of the swimmer's head the whether underwater or not by comparing the real-time measured pressure to an estimated value of over the water surface pressure. If the time-lapse spent by the swimmer exceeds a predefined maximum threshold or the measured accelerometer information shows that he has been motionless for long time period underwater, an on device alarm is triggered and a signal is sent to the servomotor connected to the deflation system of the airbag to trigger it and evacuate the swimmer.

Multiple reference frame motion estimation (MRFME) is one of main features of recent video coding standards such as H.264/AVC and HEVC. In this paper, we present a general search strategy for MRFME. The proposed method can accelerate the conventional full search algorithms without any penalty in the rate-distortion (RD) performance. Experimental results show that the proposed method can reduce the motion estimation (ME) time of the conventional algorithms up to 39.48%.

In this paper, we propose a new directional MAC protocol referred to as deafness-aware MAC (DA-MAC) distinguishing the deafness from the collision. Although a significant number of directional MAC protocols have been proposed including [1]-[3], they have not comprehensively resolved the deafness problem. With the expense of an additional narrow-band antenna, we provide distinction between the deafness and the collision. Through performance analysis, we show our DA-MAC protocol can significantly outperform the existing techniques with respect to the throughput, energy consumption, and deafness duration.

We describe a prototype system that analyzes video from a camera mounted on a TV receiver or set-top-box, showing viewers watching the TV. The system recognizes the faces of registered viewers, and estimates the level of interest that each viewer displays in the program being viewed. This information, along with receiver operation history, can be used to build viewer profiles and to offer personalized program recommendations reflecting each viewer's perceived interests.

Optical heart rate monitoring (OHRM) offers an unobtrusive solution for continuously measuring heart rate. An OHRM prototype, able to correct for movement artifacts during physical activity, proved to be valid to continuously monitor heart rate during activities including running, allowing monitoring cardiovascular condition in response to fitness and home activities.

In this study, we investigated the influence of the separate-clock structure and embedded-clock structure on the characteristics of electromagnetic interference (EMI) and audio clock jitter during high-speed serial transmission. We found that the EMI peak spectrum of a separate clock can be reduced by 11 dB if its frequency is decreased. The peak spectrum of transmission when using a separate clock is much lower than that of transmission when using an embedded clock, and results in less audio-clock jitter than transmission using an embedded clock.

Although touch pads and screens have been widely researched recently, complexity and high cost have been major issues in their implementation. In this paper, we present a new touch-sensing technique for the implementation of a simple and cost-effective touch keyboard based on the AC hum phenomenon which exists in the vicinity of any AC source. The proposed technique has the advantage of being customizable according to the demands of the user. Moreover, it can be integrated with other applications as it can be made flexible, transparent, in any size and in any color.
