Abstract :
Mesh of pyramids and pyramid of meshes implementations of an iterative image-restoration algorithm are proposed. These implementations are based on a single-step regularized iterative restoration algorithm. Both architectures are described as a composition of a mesh and a pyramid. They are compared in terms of area of the VLSI chip and its computation time
