In this study, a new video super-resolution (SR) reconstruction approach using a mobile search strategy and adaptive patch size is proposed. Based on the nonlocal-means (NLM) SR algorithm, the mobile strategy for search center and adaptive patch size are proposed to reduce the computational complexity and improve the visual quality, respectively. Based on(More)
For very low bit rate video coding, coarse-quantized DCT coefficients induce discontinuities at block boundaries, namely, blocking artifacts. Furthermore, motion-compensated prediction propagates blocking artifacts to inner-block regions of subsequent video frames. Blocking artifacts caused by motion-compensated prediction (MCP) can be solved by a(More)
Dysphagia is a common complication of strokes, and the patients usually have clinical problems such as malnutrition, significant weight loss, and aspiration pneumonia. Measuring the muscle activity pattern to describe physiology of swallowing behavior by surface electromyography (sEMG) is a simple, non-radioactive, and non-invasive method. Most of previous(More)
A microwave imaging device is used to catch the image from artificial phantom. This microwave imaging system is developed by Allwave corporation. One of the main techniques is called the field mapping algorithm (FMA). By using FMA, the electric field data of the scanning object can be obtained. After scanning, we use the simple threshold to eliminate(More)
