These are the 1-NN edit distances to the training set for each of my 9 test images. The first 4 motorbike images are showing a significantly lower edit distance than the last 5. The edit distances are computed by considering the extracted appearance patches to be words where each patch is a single character. Here, the matching cost between two image patches was computed using a straight SSD between the patches. The cost of inserting a gap was computed as the matching cost (SSD) of the patch with a canonical 11x11 patch having uniform intensity of 128.
