  • Publication number: 20250005961
    Abstract: A processor-implemented method with image processing includes detecting facial keypoints from an input face image determining a face area of the input face image and a facial feature area of the input face image based on the facial keypoints, and determining the input face image to be an invalid face image in response to the facial feature area satisfying a first preset condition, wherein the first preset condition comprises either one or both of a shape condition regarding a shape of the facial feature area, and a position condition regarding a relationship between a position of the facial feature area and a position of the face area.

  • Patent number: 11688319
    Abstract: A driving method for driving a pixel circuit. The pixel circuit includes a driving transistor, a data-writing transistor, a compensating transistor, a first initializing transistor, a second initializing transistor and a light-emitting element. The compensating transistor is connected between a gate of the driving transistor and a second pole of the driving transistor. The second pole of the driving transistor is connected to an initialization power supply through the first initializing transistor. The data-writing transistor is connected between a data voltage input terminal and a first pole of the driving transistor. The second initializing transistor is connected between a first signal terminal and a first pole of the driving transistor; and the light-emitting element is connected between the second pole of the driving transistor and a second power voltage input terminal.

  • Publication number: 20230154040
    Abstract: A method and apparatus with landmark coordinate prediction are provided. The method includes generating a multi-stage feature map for landmarks of a face image through a staged convolutional network, generating an initial query matrix by fully connecting a last-stage feature map in the multi-stage feature map using a fully connected network, where a total number of feature elements in the initial query matrix is equal to a total number of predicted landmarks of the face image, generating a memory feature matrix by flattening and connecting the multi-stage feature map, generating the predicted landmark coordinates by inputting the memory feature matrix and the initial query matrix to a decoder network of plural cascaded decoder networks.
