As a unique biometric feature that can be recognized at distance, gait has broad applications in crime prevention, forensic identification and social security. To portray gait, existing recognition methods utilize either template, where temporal information is hard to preserve, or sequence, which must keep unnecessary sequential constraints thus loses the flexibility of recognition. In this paper we present novel perspective, regarded as set consisting independent frames. We propose new...

Gait recognition is of great importance in the fields surveillance and forensics to identify human beings since gait unique biometric feature that can be perceived efficiently at a distance. However, accuracy some extent suffers from both variation view angles deficient templates. On one hand, existing cross-view methods focus on transforming templates among different views, which may accumulate transformation error large angles. other commonly used energy image template loses temporal...

Resveratrol is a natural active ingredient found in plants, which polyphenolic compound and has variety of pharmaceutical uses. Resveratrol-loaded TEMPO-oxidized cellulose aerogel (RLTA) was prepared using freeze-drying method, employing high speed homogenization followed by rapid freezing with liquid nitrogen. RLTAs were designed at varying drug-cellulose ratios (1:2, 2:3, 3:2, 2:1). It could be seen via scanning electron microscopy (SEM) that Res integrated into (TC) different ratios,...

The rapid advancement of generative models in creating highly realistic images poses substantial risks for misinformation dissemination. For instance, a synthetic image, when shared on social media, can mislead extensive audiences and erode trust digital content, resulting severe repercussions. Despite some progress, academia has not yet created large diversified deepfake detection dataset nor it devised an effective solution to address this issue. In paper, we introduce the Social media...
