METHOD FOR MEASURING PEAK SIGNAL TO NOISE RATIO BASED FRAME WEIGHT ON DYNAMIC IMAGE

, 2014
동적 영상의 프레임 가중치 기반 영상 피크 신호 대 잡음비 측정 방법이 개시된다. 멀티미디어 영상의 품질을 평가하는 항목으로 피크 신호 대 잡음비(peak signal to noise ratio)를 측정하는 방법은, 송신단에서 송신하는 원본 영상과 상기 원본 영상을 수신하는 수신단의 수신 영상을 비교하여 초기 피크 신호 대 잡음비를 계산하는 단계; 및 상기 수신 영상의 각 프레임에 대하여 손실된 패킷에 따른 가중치(weight)를 이용하여 상기 초기

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

A Deep Learning-Based Method for Enhancing the Signal-to-Noise Ratio of Star Sensor Images

Remote Sensing
In window tracking mode, stray light and detector readout noise can submerge star spot signals in star sensor images. The resulting degradation reduces centroid extraction accuracy and may even cause extraction failure, thereby preventing precise ...
