Familial exudative vitreoretinopathy (FEVR) is a hereditary disorder that can damage the retina. This retinal lead to vision loss and even blindness in late stages. Thus, early diagnosis prevention of disease's progression are critical. The purpose this study was develop an automated system for FEVR based on combining deep learning domain knowledge. A transfer scheme designed train convolutional neural network (DCNN) provide segmentation vessels. Based vessel prior clinical knowledge,...
This paper proposes a fast I-frame searching algorithm based on an analysis of statistical characteristics MPEG video stream. Computer simulations confirm that the proposed outperforms existing algorithms, which ensures quality with low computational complexity.
We demonstrated high order Smith-Purcell radiation in deep ultraviolet wavelength region. Having free electrons passing through a slot 2μm-long two-dimensional Aluminum grating, the with as short 237nm has been derived.
An integrated terahertz (THz) radiation source based on Cherenkov-radiation (CR) generated by free-space electron and plasmonic graded metallic grating is proposed investigated. The frequency range covers 0.15 to 0.5THz.
Based on a photolithography method with two-surface-plasmon-polariton-absorption effect, concentric-circle pattern linewidth of ~70nm is realized under the exposure 400nm femtosecond laser. The promising realizing optical devices light field gathering or bio-sensing.
Retinal arteriovenous nicking (AVN) manifests as a reduced venular caliber of an crossing. AVNs are signs many systemic, particularly cardiovascular diseases. Studies have shown that people with AVN twice likely to stroke. However, classification faces two challenges. One is the lack data, especially compared normal (AV) crossings. The other significant intra-class variations and minute inter-class differences. may look different in shape, scale, pose, color. On hand, could be from AV...
We demonstrate an on-chip integrated Cherenkov radiation (CR) emitter, in which the no-threshold CR could be realized and a broadband is observed with electron energy of only 0.25–1.4keV.
Compressed video data is very vulnerable to channel disturbances when transmitted through time-varying wireless with high value of BER. In this paper, a novel efficient content-adaptive spatial error concealment presented. Specifically, we adopt finite state Markov chain as mathematically tractable model for channels and investigate the corresponding patterns under different conditions. Then, by analyzing multiple features extracted from surrounding available blocks, proposed algorithm first...
Boride evolution in the transient liquid phase (TLP) repaired cracks for IN738LC alloy had important influence on mechanical properties. The microstructure of crack contained two typical zones: isothermal solidification zone (ISZ) and diffusion affected (DAZ). There were blocky acicular borides with hexagonal crystal structure DAZ, boride morphology depended interfacial distance, Cr/B content, aging time. i) As distance from ISZ/DAZ interface increased, gradually decreased began to form. ii)...
