statistical distribution theory

Based on the brief sum-up of current remote sensing image quality evaluation methods, a new statistical parameter namely distribution function is presented to evaluate fusion image, at last, we give a theory system based on the visual judgment, quantitative statistical parameters and graph comparison.

在总结已有的质量评价指标的基础上，提出了影像灰度分布函数评价指标对融合影像进行质量评价，并建立了目视观察、客观评价及图形法评价为一体的评价体系。
