Python | OpenCV BGR color palette with trackbars
OpenCV is a library of programming functions mainly aimed at real-time computer vision.
In this article, Let’s create a window which will contain RGB color palette with track bars. By moving the trackbars the value of RGB Colors will change b/w 0 to 255. So using the same, we can find the color with its RGB values.
Libraries needed: OpenCV Numpy
Create a black window with three color channels with resolution 512 x 512. Then create three ‘B’ ‘G’ ‘R’ trackbars using predefined functions of OpenCV library. Set the values of channels from 0 to 255. Merging the black window with these color trackbars.
Note: Above programs will not run on online IDE.
