1·A binarization method for digital camerabased document image was proposed. The method is a combination of the global thresholding, local thresholding and the gray gradient method.
提出了一种数码相机拍摄的文本图像的二值化方法，该方法是全局阈值、局部阈值与灰度梯度方法的结合。
2·In preprocessing of fingerprint image, four sides are discussed, including outline segmentation, filtering enhancement, segmentation binarization and thinning.
指纹图像预处理的研究包含四个方面：图像分割、图像增强、二值化和细化。
3·This paper introduces a new whole binarization method by using image gray statistical characteristic value as threshold.
本文给出了一种利用图像灰度统计特征值为阈值的全局二值化方法。
4·MFC gray-scale image processing, including open display, filtering, binarization, histogram, geometric transformations, etc.
说明：MFC灰度图像处理，包括打开显示，滤波，二值化，直方图，几何变换等。
5·After denoising, a series of operations, binarization, skeleton extraction, fringe order assignation and interpolation, were implemented and the three-dimension phase map was obtained.
对滤波后的条纹图进一步采取二值化、骨架线提取、条纹级数标定、插值一系列操作，得到物体的三维相位信息。
