Comparison of photos of the same position taken with drone at different time
To perform this task, we must use image processing algorithms and various comparasion tools. Firstly, since the pictures taken will be different, the "saturation" values and the brightness of the colors will be different from each other. So we should optimize the pictures for the best results. The histogram equation can be used for optimization.
Methods & algorithms that can be used to compare images:
It is used to find a part of a photo in another photo. Some algorithms can be used; SQDIFF, SQDIFF NORMED, TM CCORR, TM CCORR NORMED, TM COEFF, TM COEFF NORMED. Among the positive aspects of the algorithm, very good performance and low error margin but negative aspects; There is not a very wide use area. The template matching method is provided by the "matchTemplate ()" function.
