    Abstract: A traffic light image processing method and device, a computer system, a roadside device, and a storage medium are provided. The method includes: acquiring image data of a traffic light from a roadside sensor, the image data of the traffic light including a sequence of image frames over time, and the traffic light including at least two light heads; performing difference processing on two temporally adjacent image frames to obtain a difference image, a pixel value of each pixel point of the difference image being equal to a difference value of corresponding pixel points of the two temporally adjacent image frames; performing thresholding processing on the difference image to obtain a thresholding processed difference image; and determining a switched-on light head in the traffic light based on the thresholding processed difference image.

    Abstract: An image recognition method is provided, which is related to a technical field of artificial intelligence, and in particular, to a technical field of image processing. An implementation includes: performing five-sense-organ recognition on a preprocessed human face image and marking positions of the human facial five sense organs in the human face image, to obtain the marked human face image; determining human face images at multiple scales of the marked human face image, inputting the human face images of multiple scales into a backbone network model, and performing feature extraction, to obtain a wrinkle feature of the human face image at each of the multiple scales; and fusing the wrinkle feature at each scale that is located in a same area of the human face image, to obtain a wrinkle recognition result of the human face image

    Abstract: A data thinning method, a data thinning apparatus, an electronic device and a storage medium are provided, which are related to the field of map technologies. The data thinning method includes performing a line segment segmentation on N spatial objects to obtain M first line segments, and determining a spatial relationship of the M first line segments. The M first line segments traverse data of the N spatial objects, the M first line segments are not overlapped, N is an integer greater than or equal to 1, and M is an integer greater than 1. The method also includes performing a data thinning on the M first line segments to obtain M second line segments, and combining the M second line segments, according to a correspondence between the M second line segments and the M first line segments and the spatial relationship, to obtain N thinned spatial objects.
