A method for updating a coordinate of an annotated point ( a 1 ′, a 2 ′) in a digital image due to camera movement, the method being performed by an image processing device, the method comprising: obtaining a current digital image of a scene, the current digital image having been captured by a camera subsequent to movement of the camera relative the scene, wherein the current digital image is associated with at least one annotated point ( a 1 ′, a 2 ′) and wherein each at least one annotated point ( a 1 ′, a 2 ′) has a respective coordinate in the current digital image; identifying an amount of the movement of the camera by comparing position indicative information in the current digital image to position indicative information in a previous digital image of the scene, the previous digital image having been captured prior to the movement of the camera, wherein the position indicative information in the current digital image is represented by a first set of keypoints ( k 1 ′: k 6 ′) extracted from the current digital image, wherein the position indicative information in the previous digital image is represented by a second set of keypoints ( k 1: k 6) extracted from the previous digital image, wherein the second set of keypoints ( k 1: k 6) is a subset of all keypoints ( k 1: k 6) extractable from the previous digital image, wherein the previous digital image is associated with at least one annotated point ( a 1, a 2) having a respective coordinate in the previous digital image, and wherein the second set of keypoints ( k 1: k 6) is restricted to only include keypoints ( k 1: k 6) located within a predefined radius from the coordinate of the at least one annotated point ( a 1, a 2) in the previous digital image; and updating the coordinate of each at least one annotated point ( a 1 ′, a 2 ′) in accordance with the identified amount of movement of the camera and a camera homography. obtaining a current digital image of a scene, the current digital image having been captured by a camera subsequent to movement of the camera relative the scene, wherein the current digital image is associated with at least one annotated point ( a 1 ′, a 2 ′) and wherein each at least one annotated point ( a 1 ′, a 2 ′) has a respective coordinate in the current digital image; identifying an amount of the movement of the camera by comparing position indicative information in the current digital image to position indicative information in a previous digital image of the scene, the previous digital image having been captured prior to the movement of the camera, wherein the position indicative information in the current digital image is represented by a first set of keypoints ( k 1 ′: k 6 ′) extracted from the current digital image, wherein the position indicative information in the previous digital image is represented by a second set of keypoints ( k 1: k 6) extracted from the previous digital image, wherein the second set of keypoints ( k 1: k 6) is a subset of all keypoints ( k 1: k 6) extractable from the previous digital image, wherein the previous digital image is associated with at least one annotated point ( a 1, a 2) having a respective coordinate in the previous digital image, and wherein the second set of keypoints ( k 1: k 6) is restricted to only include keypoints ( k 1: k 6) located within a predefined radius from the coordinate of the at least one annotated point ( a 1, a 2) in the previous digital image; and updating the coordinate of each at least one annotated point ( a 1 ′, a 2 ′) in accordance with the identified amount of movement of the camera and a camera homography.
