In this paper, we propose a novel propagation-based stereo matching algorithm. Starting from an initial disparity map, our algorithm selects highly reliable pixels and propagates their disparities along the scan line to produce dense results. The key idea is construct segment region for each pixel with local color connectivity constraints. wise segments are efficiently used compute disparities, select determine proper propagation regions. Streaking artifacts effectively removed in refinement...

Then, extraction complementary classifiers, multiple models based...

Icariin and icariside II are flavonoids derived from Epimedium Herba, which exhibit significant pharmacological potential across various diseases. However, limited research exists regarding their interaction with human serum albumin (HSA). Therefore, this study was conducted to investigate the binding characteristics of icariin HSA through ultraviolet-visible, fluorescence, synchronous fluorescence spectroscopy, as well molecular docking analysis.

It compatible with various graphic contents including mesh, point cloud,...

The slanted lenticular sheet-based multiview display usually suffers both extrinsic crosstalk resulting from fabrication errors or assembling and intrinsic originating the leaked light two closest neighboring views. In this paper, a unified method is proposed to eliminate alleviate simultaneously by adjusting predefined view index (i.e., corresponding viewpoint number) grayscale intensity of each LCD subpixel. Two sets patterns are utilized: structured applied for building correspondence...

Human computer interaction is becoming more integrated in daily life with the proliferation of mobile devices and virtual reality technology. Hand gesture recognition a potentially promising mechanism to facilitate human interaction, however wrist-mounted surface electromyography (sEMG) hand classification particularly challenging given relatively small sEMG signals as compared traditional forearm-based sensing. This paper introduces development wristband for detecting eight air gestures...

Imitation of human behaviors is one the effective ways to develop artificial intelligence.
