According to the study research, carried out by Food and Agriculture Organization of the United Nations (FAO) in 2011, every year over the globe, there are over one-third of eatable fruits and vegetables been wasted or damaged. With the additional loss from the supply and marketing process and the waste caused by the consumer side, the total squandering every year can be accumulated up to 1.3 billion...
Three-beam laser interference is used to create spot or grating patterns by three laser beams. In this paper, effect of parameters on three-beam laser interference is discussed. Computer simulation results have shown that the parameters and their deviations of incident angles, azimuthal angles and polarization states will affect the period, contrast, shape and direction of the spots of three-beam...
In this paper, we propose a novel computer vision-based fall detection system for monitoring an elderly person in a home care, assistive living application. Initially, a single camera covering the full view of the room environment is used for the video recording of an elderly person’s daily activities for a certain time period. The recorded video is then manually segmented into short video clips containing...
This paper proposes a cartilage thickness detection and visualization method that does not utilize a shape model. The proposed method consists of three parts: volume of interest (VOI) initialization, bone segmentation, and cartilage thickness visualization. For VOI initialization, a novel 3D U-shape cuboidal filter is proposed to detect individual bones such as the femur, tibia, and patella, and for...
Communication signals are appropriately to be modeled as cyclostationary stochastic processes. The most significant advantage of cyclostationarity is its suppression on the stationary noise and interference. Therefore, cyclostationary theory has been a powerful tool in LPI (Low Probability of interception) signal processing. In non-cooperative condition, blind detection and parameter estimation of...
