Abstract
⺠We consider retractions defined by digitally continuous multivalued maps. ⺠A special kind of retractions, called (N,k)-retractions, is considered. ⺠Deletion of simple points and many thinning algorithms are (N,k)-retractions. ⺠We characterize thinning algorithms that can be modeled as (N,k)-retractions. ⺠Characterization in terms of Ronse-like conditions for topology preservation.
