Fascinating algorithm to resize pictures | |

Dr. Ariel Shamir from Efi Arazi School of Computer Science is one of the co-inventors of a clever algorithm to resize images. Usually if you have an image that is to big in size you crop or resize it. Now if you resize it, important information might get lost because some pieces in the picture are getting to tiny that you can't see them anymore (they might even get at a sub pixel level where they are merged with other pixels). On the other hand if you crop the image, parts are missing completely. That could also include important information! Another problem would be two hot spots in an image: you would need to crop and merge the two pieces somehow, which isn't always an easy task. Now the people around Dr. Shamir invented a way to resize pictures without losing important details. They have published a video on how their algorithm works. | ||
