【摘要】 介绍了一种利用开源视觉库OpenCV在Visual Studio 2005环境下实现图像阈值分割的方法。首先利用双立方插值法估算图像的光照分布,去除不均匀光照,再利用Otsu方法对图像进行阈值分割。实验表明,对传统阈值分割法难以处理的不均匀光照图像能达到良好的分割效果。更多还原

【Abstract】 An improved thresholding method using OpenCV in Visual Studio 2005 is presented. Firstly, the distribution of illumination is estimated using bicubic interpolation. After the uneven illumination is removed or decreased, the image is segmented using Otsu method. The result of experiment is showed that it woks well on uneven illuminated images which is difficult to segment using ordinary segmentation methods.更多还原
