Abstract: A method, an apparatus, and a device for target detection in consecutive images, and a computer-readable storage medium. A second frame is divided into multiple sub-images, before a target in the second frame in a video sequence is detected through a target-detecting network model. A first frame is searched, according to a preset rule for motion estimation, for a corresponding image block matched with each sub-image. Pixels of a sub-image, of which the matched image block is found in the first frame, are replaced with preset background pixels. Hence, a target repeating in both frames is replaced. Finally, the second frame subject to the replacement is inputted in to the target-detecting network model, to obtain a bounding box of a target object of the second frame and a category of such target object. An algorithm for target detection in consecutive images is optimized.
