Abstract: An image registration method includes determining connected domains in a first image and a second image. Each of the connected domains is a region formed by one or more pixels each having an amplitude satisfying a predetermined condition. The first image and the second image are a first original image and a second original image, respectively, or are obtained by performing a down-sampling process on the first original image and the second original image, respectively. The method further includes determining feature points in the first image and the second image according to the connected domains, and performing image registration on the first original image and the second original image according to the feature points. Each of the feature points is associated with a corresponding one of the connected domains.

Abstract: The present disclosure provides a tracking control method. The method includes obtaining an input image sequence; based on a detection algorithm, detecting a frame of input image in the input image sequence to obtain a tracking frame including a target object; and based on a tracking algorithm, tracking the target object in a plurality of frames of input images behind the frame of input image based on the tracking frame of the target object.
