A New Pattern Matching Algorithm Based on Adjusting the Template Image Size
Xiaoli Liu · Acta Armamentarii · 2005
In the process of tracing,the presence of differences in gray values and the distortion between the object image and the template image is inevitable.As the template image in traditional pattern matching algorithm is of the rectangle structure,so it is inevitable that the background data exist in the template image when the object is made to contain in the template image.The size of the template image in traditional pattern matching algorithm is fixed.Based on these factors,the process of tracing is instable and easily loses the object.A new pattern matching algorithm based on variable template image sizes was proposed in this paper.By applying the algorithm,the size of template image can be modified real time and the shape of template image is non-rectangular in structure.The tests show that this algorithm possesses the ability to resist distortion and adapts to complex background improved greatly.
