The morphological structures of the rickettsiae of epidemic and endemic typhus fever, Rocky Mountain spotted fever, and Q fever are similar to one another and to certain bacteria. The rickettsial organisms in common with the elementary bodies of vaccinia virus and all bacteria would appear to have a limiting membrane which surrounds a substance that seems to be protoplasmic in nature; numbers o...

Other authors represented in the present volume are primarily concerned with the question of how default notions in morphological structure should be expressed. e present chapter takes a somewhat different approach, attempting to characterize the notion of morphological “default” from the other direction by investigating the range of phenomena in morphology that deviate from the default and the...

Morphological studies and phylogenetic analysis based on the ITS sequence data showed that there is considerable differences within the Puccinia striiformis complex on members of Triticeae(Triticum and Hordeum), Dactylis glomerata and Poa pratensis. Based on the above molecular and morphological data, we suggest dividing P. striiformis as follows: - P. striiformis s. str. mainly on Triticeae. -...

Rank order morphological operators have been designed to better cope with shape variations and noise than the corresponding operators with plain structuring elements. In this paper, starting from a brief historical overview of rank order "lters and erosions/dilations in digital image processing, rank order based morphological operators are surveyed. We also highlight the relations between these...

We discuss a definition of Morphological Cellular Neural Networks (MCNN) where the state change operator are Auto-associative Morphological Memories (AMM). The fast convergence properties of AMM and the shape of its fixed point set make the MCNN dynamics trivial. However, segmentation results are poor. We propose a Morphological Cellular Automata (MCA) with assured convergence to a state charac...
