  • Publication number: 20240412503
    Abstract: This application provides a method for training a portrait detection model, a portrait detection method, an electronic device, and a computer-readable storage medium. The portrait detection method is performed by utilizing a portrait detection model, and the portrait detection model is trained by acquiring at least one first image and at least one second image, acquiring a fused fisheye image from the first image and the second image, and training the portrait detection model by utilizing the fused fisheye image. The first image is a planar image including a portrait, and the second image is a fisheye image including a portrait. The fused fisheye image includes the portraits in the first image and the second image. The method is implemented by the electronic device and can improve the portrait detection accuracy using the portrait detection model.

  • Publication number: 20240412490
    Abstract: This application provides a pedestrian detection method, a method for training a pedestrian detection model, an electronic device, and a computer-readable storage medium. The pedestrian detection method includes: acquiring an image to be recognized; inputting the image into a multi-task recognition network to acquire a predicted pedestrian location and a predicted pedestrian attribute in parallel; and correlating the predicted pedestrian location and the predicted pedestrian attribute to output a detection result. The pedestrian detection method utilizes the multi-task recognition network to acquire the predicted pedestrian location and the predicted pedestrian attribute in parallel, and the detection result containing the predicted pedestrian location and the predicted pedestrian attribute is acquired only by inputting the image to be recognized once, thereby improving detection efficiency, quickly obtaining the detection result and saving device resources.
