为了进一步提高现有工业层叠薄型钢板计数方法的精准性和效率，研究基于面阵CCD 图像检测的薄型钢板计数方法。基于CLAHE(Contrast Limited Adaptive Histogram Equalization)原理、二维均值滤波及形态学膨胀腐蚀优化原理，提出了粗背景分离并修正阈值的自适应OTSU 分割算法。针对传统Hough 变换的参数空间峰值点漏检或误检等不足，提出了基于自相关特征分割的参数空间波峰提取算法。实验表明，本文测数方法对0.5 mm 以上规格的层叠钢板堆垛统计准确，实时性强，鲁棒性好。

Color inconsistency is an urgent problem to be solved in free viewpoint television. In this letter, a new color correction method is proposed by using disparity vector information. At first, we separate foreground and background from the scene with a method of mean-removed disparity estimation. Then the correction parameters are estimated by adopting linear fitting for foreground and background regions, respectively. Next, with expectation-maximization algorithm, we integrate correction parameters of foreground and background to get the final corrected image. Finally, video tracking technique is performed to correct multi-view video. Experimental results show that the proposed method is quite effective.
