The present application discloses a method performed by an electronic apparatus for detecting and tracking a target object. The method includes obtaining a first frame of scene; performing object detection and recognition of at least two portions of the target object respectively in at least two bounding boxes of the first frame of scene; obtaining a second frame of scene, the second frame of scene being later in time than the first frame of scene; and performing object tracking of the at least two portions of the target object respectively in the at least two bounding boxes of the first frame of scene.
