UPLOADING
Our software utilizes an algorithm that calculates cross-correlation in the spatial and frequency domain rather than comparing images directly. This algorithm is considered a basic one and it does not help comparing images being too noisy or rotated relative to each other. In most of the cases it, however, shows excellent results.
Once the calculation has been complete, the uploaded files will be removed from our servers.
