1. A method for semi automatic target initialization (100) comprises the steps of,inputting an image coordinate by user (101),selecting an initial window around the image coordinate by center-surround histogram distance (102),generating saliency map of the window (103),binarizing the saliency map (104),selecting a target (105),outputting a bounding box enclosing the target (106) and characterized by the following steps for binarizing the saliency map;

  • detecting local maxima of the saliency map and sorting them in descending order to obtain a vector LocalMaxsorted (402),calculating a normalized laplacian of the vector with the formula;
