Abstract: Embodiments of a generative framework comprise cooperative learning of two generative flow models, in which the two models are iteratively updated based on the jointly synthesized examples. In one or more embodiments, the first flow model is a normalizing flow that transforms an initial simple density into a target density by applying a sequence of invertible transformations, and the second flow model is a Langevin flow that runs finite steps of gradient-based MCMC toward an energy-based model. In learning iterations, synthesized examples are generated by using a normalizing flow initialization followed by a short-run Langevin flow revision toward the current energy-based model. Then, the synthesized examples may be treated as fair samples from the energy-based model and the model parameters are updated, while the normalizing flow directly learns from the synthesized examples by maximizing the tractable likelihood. Also provided are both theoretical and empirical justifications for the embodiments.

Abstract: The present disclosure provides a non-contact fatigue detection system and method based on rPPG. The system and method adopt multi-thread synchronous communication for real-time acquisition and processing of rPPG signal, enabling fatigue status detection. In this setup, the first thread handles real-time rPPG data capture, storage and concatenation, while the second thread conducts real-time analysis and fatigue detection of rPPG data. Through a combination of skin detection and LUV color space conversion, rPPG raw signal extraction is achieved, effectively eliminating interference from internal and external environmental facial noise; Subsequently, an adaptive multi-stage filtering process enhances the signal-to-noise ratio, and a multi-dimensional fusion CNN model ensures accurate detection of respiration and heart rate.

Abstract: A sectional type card feeding mechanism and method. The mechanism includes: a rear section mechanism including a rear section frame and a rear section belt, the rear section belt being movably connected to the rear section frame in a lengthwise direction of the rear section frame to convey cards; and a front section mechanism including a front section frame which is connected to an end of the rear section frame, the rear section belt driving the cards to be transferred to the front section frame to be discharged. The process of card feeding is divided into two sections. Cards are placed on the rear section belt of the rear section mechanism, and after the rear section belt conveys the cards to one end of the front section frame, the cards are sent to the other end of the front section frame to be discharged.
