摘要
在像素级配准的基础上,通过对多项式细分算法的改进,提出了一种基于小波分析的亚像素配准算法,并对配准算法的精度进行了分析研究。仿真结果表明,该算法效果良好,达到亚像素级精度。
Image registration is an important task in the field of computer vision and pattern recognition, and is applied in remote sensing, medical imaging and object indentifying of multi-sensor fusion. In this paper, a new subpixel registration method based on wavelet analysis was proposed by improving polynomial subdivision algorithm and pixel level registration. Furthermore, the precision of the method was also analyzed. The simulation results show that the methods can reach the precision of sub-pixel.
