Abstract

Disclosed in embodiments of the present application are an image processing method and apparatus, and a related device, which are applicable to the technical field of computers. The method comprises: obtaining a service image comprising a target object, obtaining a template image, and determining an object detection region from the template image; looking up for a region matching the object detection region in the service image, determining a found region as an initial positioning region, and determining a pixel position transformation relationship on the basis of a pixel position of a pixel in the object detection region and a pixel position of a pixel in the initial positioning region; on the basis of the pixel position transformation relationship, determining a local mapping region corresponding to a local reference region in the service image, and using the local mapping region as a target positioning region; and identifying a foreground region in the target positioning image, and performing edge curve fitting processing on pixels in the foreground region, to obtain an edge curve of the target object. By using the embodiments of the present application, the accuracy and stability of the edge curve obtained by fitting can be improved.
