The present work proposes a simple procedure to evaluate the efficiency of a given image processing technique applied to weld radiographs. Specifically, special attention is given to the problem of how to evaluate whether or not a threshold value was suitably set in order to preserve relevant ...

in an image. In spite of this variety of techniques, threshold selection is still a difficult problem inimage processingand is most successful when the solution is application dependent. In order to set an appropriate threshold for temporal segmentation of video sequences, we draw upon the same ...
In image processing, Otsu [4] proposed a method for determining the threshold. Binarizing an image means that the result contains two values, 0 and 255. Pixel values are compared against the threshold. If greater, the pixel becomes 255; if lower, it becomes 0. The threshold has to be de...

Graph. Image Process. 46, 82–95 ,1989. 过分割后处理——区域融合 ( Region Merging) 分水岭算法对噪声比较敏感,容易出现过分割。常见的处理过分割的方法包括 1). 预处理,图像降噪; 2). 应用标记 (marker)。选择标记需要用户的参与,图像结构的先验知识; 3). 区域融合 本节介绍,基于区域近邻图(Region ...
Full size image In Fig. 2b, we plot the logical error per cycle versus detection probability for the distance-3, distance-5 and distance-7 codes. We find that the three curves cross near a detection probability of 20%, roughly consistent with the crossover regime explored elsewhere17. The ...
