The search for similar images can be useful when searching for duplicate files that might have different file **types** (i. e. imageA.png has a duplicate imageA.jpg) and/or different file **sizes** (f. e. imageA.png (100MB) has a duplicate imageA.png (50MB)). In these cases, the MSE between the two image tensors might not be exactly == 0, hence they would not be classified as being duplicates even though in reality they are. Setting ``similarity`` to ``"similar"`` searches for duplicates with a certain tolerance, increasing the likelihood of finding duplicate images of different file types and sizes. Depending on which ``similarity`` level is chosen, the ``lazy`` parameter should be adjusted accordingly (see :ref:`lazy`).
