摘要: 在详细分析造成大型影像库中色调差异成因的基础上,通过比较几种影像数字镶嵌时常采用的色调过渡匹配平衡方法,提出了一种充分考虑影像本身特征的相邻相关影像色调调整平滑过渡方法。同时为了减少大幅面影像调整时调整误差的空间传递性,给出了基于四叉树的多次调整法。

Abstract: This paper analyzes the reasons causing hue(or gray) difference of large-scale image database.Then on the basis of the comparison of some general methods,the paper presents a new hue(or gray) adjustment and smoothness transition method.Meanwhile,in order to reduce spatial transfer error caused by adjusting large-scale images,an innovative multi-time adjustment algorithm based on quad tree is put forward.
