Question

在OpenCV中，我可以创建RGB的轨迹栏但我的问题是： 当在轨迹栏上更改RGB值时，如何更改图像的颜色？

Answer 1

There is a python example on how to do this on the OpenCV websites. You could do a very similar thing in C++ without too much difficulty

The python tutorial is here:

http://docs.opencv.org/trunk/doc/py_tutorials/py_gui/py_trackbar/py_trackbar.html

To do this in C++ replace the python commands with C++ alternatives. most of them you can find on this page here:
