Multimodal Spatiotemporal Networks for Sign Language Recognition
IEEE Access, 2019 Different from other human behaviors, sign language has the characteristics of limited local motion of upper limb and meticulous hand action. Some sign language gestures are ambiguous in RGB video due to the influence of lighting and background color ...

Action tube extraction based 3D-CNN for RGB-D action recognition [PDF]
, 2018 In this paper we propose a novel action tube extractor for RGB-D action recognition in trimmed videos. The action tube extractor takes as input a video and outputs an action tube.

A wavelet-based decomposition method for a robust extraction of pulse rate from video recordings [PDF]
PeerJ, 2018 Background Remote photoplethysmography (rPPG) is a promising optical method for non-contact assessment of pulse rate (PR) from video recordings. In order to implement the method in real-time applications, it is necessary for the rPPG algorithms to be ...

Viewpoint Invariant Action Recognition Using RGB-D Videos
IEEE Access, 2018 In video-based action recognition, viewpoint variations often pose major challenges because the same actions can appear different from different views. We use the complementary RGB and Depth information from the RGB-D cameras to address this problem. The proposed technique capitalizes on the spatio-temporal information available in the two data streams

RESEARCH OF IMAGES FILTRATION METHODS IN COMPUTER SYSTEMS
Сучасні інформаційні системи, 2021 It is known that human eyes are less sensitive to color, than to their brightness. In the RGB color space, all three components are considered equally important, and they are usually stored with the same resolution. However, you can display a color image

Evaluating RGB channels in remote photoplethysmography: a comparative study with contact-based PPG
Frontiers in Physiology, 2023 Remote photoplethysmography (rPPG) provides a non-contact method for measuring blood volume changes. In this study, we compared rPPG signals obtained from video cameras with traditional contact-based photoplethysmography (cPPG) to assess the ...
