We present a histogram-based real-time solution to detecting directly irradiated regions in digital fluoroscopic images. Our method leverages the power of model matching, machine learning and domain knowledge to characterize and segment images using histograms. The input image is automatically identified as containing partial, all, or null direct radiation. The regions with direct radiation are segmented...
After a long in-service period, the electrical aging phenomenon of Nylon 6 may cause insulation degradation. Most of the researches focus on AC/DC or room temperature conditions. Less attention is paid to the nanosecond pulses conditions. In this paper, frequency effect on the electrical tree growth of nylon 6 was investigated. A solid-state pulse generator MPC50D was used to export nanosecond pulses...
We address the problem of editing facial expression in video, such as exaggerating, attenuating or replacing the expression with a different one in some parts of the video. To achieve this we develop a tensor-based 3D face geometry reconstruction method, which fits a 3D model for each video frame, with the constraint that all models have the same identity and requiring temporal continuity of pose...
The prevention of pressure ulcers remains a significant problem in rehabilitation engineering, cushion takes an extra important role in the prevention of pressure sores for high-risk people who require wheelchairs for movements. The aim of this study was to design a cushion preventing pressure ulcers. A new efficient method to manufacture custom-contoured cushion (CCC) was proposed, and clinical research...
This paper probes into the technique of phonetic explanation of smart guide in the scenic spots, and discusses the possibilities of accessing to data, data matching and phonetic explanation. In the aspect of accessing data, we provide two methods of ensuring scenic scale. And we solve the repeatedly playing phonetic explanation by software programming.
