opencv createtrackbar size
The function may scale the image, depending on its depth: If the image is 8-bit unsigned, it is displayed as is. If the image is 16-bit unsigned or 32-bit integer, the pixels are divided by 256. That is, the value range [0,255*256] is mapped to [0,255]., While there is no argument in OpenCV to specify the step size, you can modify your algorithm to incorporate the same: Currently you have a ...
