A modified target recognition algorithm was proposed. The algorithm used gradient characteristics as features to complete the template matching, which only used the main direction of the gradient and the minor gradient feature was removed by DOT(dominant orientation templates)algorithm. The template feature, which was made binary by fusing affine projection transformation algorithm, could improve the recognition rate of identifying multiple objects at the same time or the same object from different perspective. The experiments demonstrated that the proposed algorithm could get better recognition rate and was robust for the object with poor texture, small deformation, small translation and light transformation %K 主导梯度方向 %K 目标识别算法 %K 模板特征二进制化 %K 模板匹配 %K 仿射投影变换 %K < %K br> %K template characteristics of binary %K affine projection transformation %K template matching %K the dominate gradient direction %K target recognition algorithms %U http://gxbwk.njournal.sdu.edu.cn/CN/10.6040/j.issn.1672-3961.0.2016.377
