Abstract: A method of estimating a motion of a real-time image target between successive frames according to an embodiment of the present invention is a method of estimating a motion of a real-time image target between successive frames by a motion estimation application executed by at least one processor of a terminal, including detecting a target object in a first frame image, generating a first frame-down image by downscaling the first frame image, setting a plurality of tracking points TP for the target object in the first frame-down image, obtaining a second frame image consecutive to the first frame image after a predetermined time, generating a second frame-down image by downscaling the second frame image, and tracking the target object in the second frame-down image based on the plurality of tracking points TP.

Abstract: A method of setting a dynamic image threshold for two-dimensional identification code detection by a threshold setting application 111 executed by at least one processor of a terminal 100, comprises: acquiring an identification code image I obtained by photographing a two-dimensional identification code; converting the acquired identification code image I into a binarized image BI; detecting a two-dimensional identification code in the converted binarized image BI; and providing a predetermined application service based on the detected two-dimensional identification code. The converting of the identification code image I into a binarized image BI includes: dividing the identification code image I into a plurality of regions; calculating a binarization reference threshold BT for each of the plurality of divided regions; performing binary thresholding on each of the plurality of divided regions based on the calculated binarization reference threshold BT; generating a plurality of binarized divided images BDI based on the performed binary thresholding; and generating the binarized image BI by combining the plurality of generated binarized divided images BDI.

Abstract: Provided is a method for selecting key points for real-time tracking in a mobile environment, which is used by a key point application executed by at least one processor of a computing device to select key points for real-time tracking in a mobile environment. The method comprises obtaining a target object image capturing a target object; extracting a plurality of temporary key points from the obtained target object image; determining confirmed key points by filtering the plurality of extracted temporary key points according to a predetermined distribution criterion; setting the confirmed key points as final key points for the target object image; storing target object tracking information including the final key points set for the target object image; and providing the target object tracking information to an application executing a predetermined function through the target object tracking in a mobile environment.
