基于Qtsu法和直方图规定化相结合的苹果图像分割研究

针对自然光下,苹果分割易受光线影响而导致目标区域分割受损的问题,提出了一种基于最大类方差阈值分割法(Qtsu法)和直方图规定化相结合的图像分割方法。对预处理后的苹果图像先进行直方图规定化处理,然后再利用Qtsu法对图像进行分割。实验结果表明,利用论文的方法对苹果进行分割后缩小了目标区域边缘的缺失,对目标与背景进行了有效的区分。

Aiming at the problem that apple segmentation is easily affected by light,an image segmentation method based on maximum variance threshold segmentation(Qtsu)and histogram specification are proposed.The pre-processed apple image is first processed by histogram specification,and then the image is segmented by Qtsu method.The experimental results show that after the segmentation of the apple,the lack of the edge of the target region is reduced,and the target and background are distinguished effectively.
