摘要
为了提高农作物叶部病害识别的可靠性,本文提出基于小波变换算法的农作物叶部病害图像处理技术。在图像分解的基础上,应用二维离散小波变换,论述了二维小波变换在农作物叶部图像去噪和图像增强中的应用。仿真实验结果表明此方案能够有效改善图像质量,提高对象识别的可靠性。
This paper brings forward image processing technology based on wavelets transform algorithm about the diseases of the crop leaves.It adopts two-dimensional wavelets transform.Based on the image decomposition,the noise elimination and the enhancement of the crop leaves image are analyzed.Results show that the method can effectively amend the image quality and improve the dependability of the object recognition.
