It is well known that blink, yawn, and heart rate changes give clue about a human's mental state, such as drowsiness fatigue. In this paper, image sequences, the raw data, are captured from smart phones which serve non-contact optical sensors. Video streams containing subject's facial region analyzed to identify physiological sources mixed in each image. We then propose method extract blood volume pulse eye blink yawn signals multiple independent simultaneously by multi-channel second-order...

Diabetic retinopathy (DR) has long been recognized as a common complication of diabetes, making accurate automated grading its severity essential. Color fundus photographs play crucial role in the DR. With advancement artificial intelligence technologies, numerous researchers have conducted studies on DR based deep features and radiomic extracted from color photographs. We combine to design feature fusion algorithm. First, we utilize convolutional neural networks extract employ methodologies...

An appearance model adaptable to changes in object is critical visual tracking. In this paper, we treat an image patch as a two-order tensor which preserves the original structure. We design two graphs for characterizing intrinsic local geometrical structure of samples and background. Graph embedding used reduce dimensions tensors while preserving graphs. Then, discriminant space constructed. prove propositions finding transformation matrices are map tensor-based graph space. order encode...

Seismic random noise suppression presents two main challenges: achieving thorough while simultaneously ensuring complete restoration of effective signal content. However, due to the complexity noise, existing denoising methods often only achieve an awkward balance between removing and restoring signals. In this paper, we propose a novel model based on downsampling super-resolution. By decoupling processes, our method reduces difficulty addressing these challenges mitigates likelihood...

ABSTRACT Radial‐trace time–frequency peak filtering filters a seismic record along the radial‐trace direction rather than conventional channel direction. It takes spatial correlation of reflected events between adjacent channels into account. Thus, performs well in denoising and enhancing continuity events. However, there is often random noise whose energy concentrated certain directions; these directions correlative. We refer to this kind (that distributed randomly time but correlative...

This paper proposes a new unsupervised fuzzy feature mapping method based on fMRI data and combines it with multi-view support vector machine to construct classification model for computer-aided diagnosis of autism. Firstly, multi-output TSK system is adopted map the original linear separable high-dimensional space. Then manifold regularization learning framework introduced, proposed. Finally, SVM algorithm used tasks. The experimental results show that in this can effectively extract...
