53results about How to "Facilitate face recognition" patented technology

An apparatus for recognizing faces with different illuminations may include a processor and memory storing executable computer program code causing the apparatus to at least perform operations including detecting and extracting face data of a first candidate face of a first image and a second candidate face of a second image. The first image is associated with a first light intensity and the second image associated with a second light intensity different from the first light intensity. The computer program code may further cause the apparatus to analyze face data to determine whether the first candidate face corresponds to an area in the first image that is substantially the same as an area of the second candidate face and evaluate data of the first and second areas to determine whether the first and second candidate faces are valid or invalid faces. Corresponding methods and computer program products are also provided.

The invention provides a face image reconstruction method based on identity information, comprising: Step 1, creating a deep network model; Step 2, reading a pre-trained face recognition model; Step 3, down-sampling the training data and Clipping processing; step 4, input the training data into the deep network model to obtain the reconstructed image; step 5, input the reconstructed image into the face recognition model to obtain the feature vector; step 6, input the original image after clipping In the face recognition model, get the feature vector; step 7, calculate Quadruplet-loss; step 8, calculate MSE-Loss; step 9, update the parameters of the deep network model through back propagation; step 10, through the image before and after reconstruction , and the corresponding label information, update the weight parameters of the face recognition model; step 11, repeat steps 3 to 10, until the loss function value in step 9 converges.

The invention discloses a method, device and medium for intelligent monitoring and identification of the surrounding environment of a cashier. The method includes video monitoring, target tracking, interactive behavior detection and identification; Markov Monte Carlo uses the human body in the surveillance video as the target for multi-target tracking to obtain a tracking video including multiple target tracking trajectories; interactive behavior detection is: extracting features from the tracking video and constructing combined features to pass through the convolutional neural network The algorithm judges the facial avatar and its feature points of the human target, and then uses it to judge whether the head posture and gaze angle are abnormal, and detects the interaction behavior if it is abnormal; the interaction behavior recognition is: if there is an interaction behavior, further Identify the type of interaction. The invention can monitor people and objects in the withdrawal area in real time, and automatically detect and identify people's behavior.

An intelligent face recognition device based on automatic induction opening and closing, including a casing, a top plate on the casing, a shaft seat connected to the bottom of the casing, a motor connected to the bottom of the top plate, a camera in the middle of the front side wall of the top plate, and a camera in the middle of the front side wall of the top plate. A first chute is provided on the side wall. The first slide block is connected to the baffle. The rear side wall of the baffle is connected to the cleaning block. There is an elastic telescopic rod at the bottom of the top plate. The lower end of the movable rod of the elastic telescopic rod is connected to the horizontal bar. The left and right sides of the horizontal rod Vertical plates are connected at both ends, and there are several fan blades at the outer ends of the movable rods of the two telescopic shafts. This device blocks the camera by the baffle so that the camera can avoid sunlight exposure, and can also keep the baffle away from the camera, thereby facilitating the user's face recognition when needed. By controlling the rotation of the output shaft of the motor, the air blows on both sides of the center console. The cold air blown out of the mouth can quickly diffuse into the car body. By controlling the up and down reciprocating movement of the vertical plate, the cold air is blown in all directions, quickly disturbing the air in the car body.

The invention discloses a dual identification device based on access control card and face recognition, which belongs to the technical field of access control, and can innovatively exchange the subject of identity authentication power, and the residents themselves can grasp and authenticate the identity, and integrate face recognition To the existing access control card, the access control card will collect and compare information during identity authentication, so as to complete the self-authentication of the residents, and there will be no interaction of the residents' personal information with the access control system, only after the authentication is passed Sending the authentication pass signal from the access control card to the access control system can not only greatly improve the privacy and security of residents' personal information, but also provide residents with certain protection in the information age of data explosion, and at the same time fully demonstrate the care of humanism. The power of identity authentication is handed over to the residents, which can effectively avoid the contradiction between the property and the residents, increase the harmony of the community, and provide great convenience in life, which has great promotion value.
