Abstract: An image segmentation method, apparatus, and a storage medium are provided. The method includes: selecting a current image frame in a video according to a time sequence of the video; determining a reference image frame before the current image frame in the time sequence; obtaining first location information of a target object key point in the reference image frame; performing an affine transformation on the current image frame with reference to an affine transformation relationship between the first location information and a target object key point template to obtain a target object diagram; performing a key point detection on the target object diagram to obtain second location information of the target object key point; segmenting a target object from the target object diagram to obtain segmentation information; and obtaining the target object from the current image frame according to the segmentation information and the second location information.
