OpenCV - 在MouseOver上查看像Matlab这样的像素值 [英] OpenCV - view pixel values like Matlab on MouseOver

问题描述

我一直在寻找OpenCV中的实用工具，它像Matlab的图像查看器一样工作，不像matlab那样功能齐全，但至少会显示具有放大/缩小功能的像素值。

I have been looking around in vain to find a utility in OpenCV that works like the image viewer of Matlab, not fully functional as matlab, but atleast shows pixel values with zoom in/out functionality.

非常感谢任何指导/指示/链接

Any guidance/directions/links much appreciated

谢谢

推荐答案

实际上，如果使用qt构建opencv，则所需的功能已经可用。
有关示例图像，请参见此处，并这里有关如何使用qt构建opencv的详细信息。

Actually the functionality you want is already available, if you build opencv using qt. See here for an example image, and here for details on how to build opencv with qt.
