Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] refer to figure 1 As shown, the present invention designs a method for effectively improving the target deviation of the manually selected initial frame, and the steps are:

[0029] S1, for the input initial frame image, the target center of the image is selected manually, and there is often a certain deviation at this time, so it is necessary to go to the next step.

[0030] S2, perform enhanced preprocessing on the initial frame image: in the case of small infrared targets or dim targets, the background in the histogram is not very distinguishable from the real target, and it is often difficult to have a good effect. High or too low images are corrected to enhance contrast. This method is simple to calculate and has less delay: by tran...

Abstract

The invention discloses a method for automatically extracting an initial frame image target in target tracking, which comprises the following steps of: sequentially carrying out manual coordinate selection, image enhancement, significance detection and morphological processing on an input image, and then calculating a corrected coordinate; compared with other methods based on deep learning, the rapid automatic extraction method is small in calculation amount, low in calculation delay, adaptive and controllable in process, and very suitable for deployment and application of an embedded platform with computing power limitation.

Description

technical field [0001] The invention belongs to the technical field of image processing, and particularly relates to a fast automatic extraction method for an initial frame image target in target tracking. Background technique [0002] Object tracking is a very common and important application in vision tasks. For the input image sequence or video, quickly determining the target that needs to be tracked is an important step in whether the target can be tracked continuously. [0003] In complex scenes or when the target to be tracked is not clear, manual target selection is the most reliable method, but manual target selection often produces deviations. Fast real-time tracking and positioning of specific objects of interest is widely used in many visual scenes and has become an important function. [0004] For the target to be tracked in the initial frame image, it is difficult to ideally select in many cases, which causes the subsequent tracker to use the background or oth...
