This paper presents analogic cellular neural network universal machine
algorithms for some important image processing tasks, Templates are g
iven for skeletonizing black-and-white and grey-scale images, A method
is presented enhancing the quality of copying machines by removing sc
ratches from the copied images, Finally, a similar method is used to e
nlarge images, All templates use only a nearest neighborhood, therefor
e being well suited for VLSI implementation,
