基于十字线灰度图像清晰度模型的构建与应用

On Constructing and Applying Clarity-evaluation-model of the Cross-line Gray-scale Image

针对图像清晰(聚焦)度评价函数种类多、计算复杂、尚无统一标准的现状,构建一种十字线灰度图像清晰(聚焦)度评价的理论模型,分析实际应用中理论模型存在的问题,然后提出图像清晰(聚焦)度评价改进模型。实验表明:清晰(聚焦)度评价改进模型符合十字线灰度图像实际,具有应用价值。

In view of the current situation on various functions, complicated calculation and non- uniform standard of Clarity （Focus） - evaluation - model, the paper constructed a theory model on Clarity（Focus） - evaluation- model of the Cross- line gray -scale image, analysed the existed problems of the proposed theory model in practical application, and proposed the improved models of Clarity（Focus） - evaluation - model. The experimental results show that the improved model accords with the reality of the Cross - line gray - scale image and it is worth applying.
