C ++图像库-查找颜色的像素并使它们变为白色，其他一切变为黑色

[英]C++ image library - finding pixels of a colour and making them white, everything else black

原文 2012-05-19 14:08:05 9 3 c++/ image-processing

I'm looking for a C++ image processing library with which I would be able to find all pixels of a certain colour, with a user-specified tolerance, and colour them white and everything else in the picture black. 我正在寻找一个C ++图像处理库，通过该库，我可以找到具有用户指定公差的某种颜色的所有像素，并将它们着色为白色，并将图片中的所有其他颜色着色为黑色。 Do you know of any? 你知道吗

If it were a C++ library, not one of plain C ones, which I'm allergic to, it would be a bonus. 如果它是一个C ++库，而不是我过敏的普通C库之一，那将是一个额外的好处。

You should check OpenCV. 您应该检查OpenCV。 It has both C and C++ (based on OO principles) APIs. 它同时具有C和C ++（基于OO原理）API。

OpenCV可以完成此任务以及更多！

Or perhaps a CImg - a wonderful header-only image manipulation library. 或CImg-一个很棒的仅标头图像处理库。
