摘要: Two models of object perception are compared: recognition by components (RBC), proposed Biederman, and structural information theory (SIT), initially Leeuwenberg. According to RBC a complex is decomposed into predefined elementary objects, called geons. SIT, the decomposition guided regularities in object. It assumed that simplest all possible interpretations any perceptually preferred. The comparison deals with two aspects models. One representation simple objects—various definitions axes considered. shown more these account for regularity thus they agree better representations predict classification. Another topic concerns assumptions underlying models: identification geons mediated cues which supposed be invariant under varying viewpoints objects. argued such not based on this inva...
