Color component value afterwards, summing elements 23 again carry out the negated color component value of each pixel according to color type correspondence tired
Add, the color component value after adding up is as the mark of target tracking object.
For example, a white pixel point (0,0,0) is carried out color and is negated, i.e., each face is individually subtracted with 255
Colouring component value then obtains a black pixel point (255,255,255).If acquiring unit 21 gets every in target tracking object
The color component value of a pixel is respectively (100,200,100), and (100,150,100) ... ..., then color negates unit 22 for institute
Target tracking object is stated to carry out obtaining the negated color component value of each pixel, i.e. (155,55,155) after color negates,
(155,105,155) ... ..., summing elements 23 carry out the negated color component value of each pixel according to color type is corresponding
It is cumulative, i.e., (155+155+ ..., 55+105+ ..., 155+155+ ...), if the cumulative color component value that obtains is (a, b, c), then will
The mark of (a, b, c) as target tracking object.
For certain target tracking objects (such as automobile), the color of group pixel is usually constant, thus is passed through
The color component value that above-mentioned calculation obtains can be used as the mark of target tracking object, the mobile object in display screen compared with
When more, target tracking object and other mobile objects can quickly be distinguished by the matching of color component value.
