Study on Point of Contact on Periphery and Frequency Ratio in Li Sa Ru's Graph

利萨如图周边切点与频率比的研究

Although the multi-scale wavelet transform has obvious advantages, it is easily leads to phase deviation and affects the image fusion quality because of the lack of translation invariance;② The spatial frequency ratio which could reflect regional similarity among images was defined.

在肯定小波变换作为图像多尺度融合工具所具有明显优势的同时，指出了其因缺乏平移不变性易导致相位偏差降低融合质量的不足；②定义了能够反映图像之间区域相似程度的空间频率比概念。
