摘要:Among image halftoning algorithms, direct binary search (DBS) minimizes the total squared perceived error instead of using heuristic approaches. Therefore, it can generate halftone output with the best quality. The limitation of DBS is that its halftone pattern is controlled...

摘要:We introduce a simple but effective deep fully connected neural network (FNN) to solve the edit propagation as a multiclass pixel-level classification task. We construct the feature space using three- (or one-) dimensional normalized RGB (or grayscale) vectors and spatial coordin...

摘要:Significance: Knee osteoarthritis (OA) is a common joint disease causing chronic pain and functional alterations (stiffness and swelling) in the elderly population. OA is currently treated pharmacologically with analgesics, although neuromodulation via transcranial direct current...

摘要:To overcome the staircase effect and texture loss of total variation (TV), a nonblind image deblurring method that combines the multidirectional fractional-order TV and the traditional TV is proposed. First, a four-directional fractional-order TV (FOTV4) model is put forward to e...

摘要:Significance: Monitoring of cerebral perfusion rather than blood pressure changes during a head-up tilt test (HUTT) is proposed to understand the pathophysiological effect of orthostatic intolerance (OI), including orthostatic hypotension (OH), in Parkinson’s disease (PD) ...

摘要:Significance: It has been reported that children with attention-deficit hyperactivity disorder (ADHD) have impairment in the recognition of angry but not of happy facial expressions, and they show atypical cortical activation patterns in response to facial expressions. Howev...

摘要:A one-dimensional photon crystal structure is proposed to design an omnidirectional broadband reflector. The structural parameters are optimized to reflect complete solar spectrum (0.3 to 2.3  μm) for both TE and TM polarized light. The design analysis is carried o...

摘要:A microscopic nonlinear quantum theory of the interaction of coherent electromagnetic radiation with gapped bilayer graphene is developed. The Liouville-von Neumann equation for the density matrix is solved numerically at the multiphoton excitation regime. The developed theo...
