摘　　要：以分形理论为基础，为空中人造目标的红外图像建立了一个新模型，提取出具有较好几何不变性的特征——目标和干扰物灰度曲面的分形维数随尺度的变化规律，并以这种规律作为识别特征．将分形特征与传统的特征作了比较．大量的实验及理论分析表明。A new model based on fractal theory for the infrared images of man made Air targets was founded. Fractal feature based on geometric invariation was extracted,which is the variation of fractal dimension of target gray surface with scales.In contrast to the traditional image features,recognition by this feature will have higher recognizing ability and reliability shown by experiments and theoretical analysis.
