I apply ORB feature matching algorithm between two images which are taken from approximately same location and have same view on different times. Due to illumination changes, ORB is struggling to match the features.
What should I do to improve matching performance?
I share source images here
ORB is struggling to find good quality matches between two images given above.
I tried to convert to HSV space, then multiplied V values by decimal values for all pixels to diminish intensity, then converted back to RGB but it gave no success.
