Abstract:
1. An object tracking method, comprising: storing a picture information; detecting positional information of an object from the picture information; detecting a region of the object in the picture information based on the positional information; detecting a feature properties of the object located in the region; storing the positional information, the feature properties and the region of the object; predicting a position of the object of a next frame in the picture information from the position information; determining a predictive area of the next frame where the region is to be moved based on the predicted position of the object of the next frame; and verifying the feature properties of the object within the predictive area of the next frame; and outputting as an object region, a region of the predictive area that resembles the feature properties most based on the verified result in the verifying process, wherein the predicting process includes: predicting a first position of the object of the next frame based on the positional information; predicting a second position of the object of the next frame based on a position of the object of the previous frame; selecting one of the predicted first position of the object of the next frame and the predicted second position of the object of the next frame; and outputting the predicted position of the object of the next frame selected in the selecting process.
