基于目标特征的图像预处理技术

Preprocessing for Color Images Based on the Features of the Target

结合建筑物搜索与识别的实例,提出了有利于保留目标特征的二值图像平滑算法和水平分割算法,改进了中心差分算子的边缘检测方法,并采用基于边缘特征的二值化算法对图像进行预处理.实验表明,这种基于目标特征的图像预处理方法对各种条件下采集的图像都能达到较好的处理效果,并取得了令人满意的速度.

In this paper, taking Building Detection and Recognition as an instance, an approach of preprocessing based on the features of the target is discussed. The approach proposes a smoothing algorithm. used for binary image, a horizontal segmentation algorithm Then it uses a binarization algorithm based on edge features and an edge detection algorithm based on improved center difference operator.The experiment shows that this approach of preprocessing can give quick and acceptable results to images when scaling, different angles of view and various conditions of sunlight involved.
