Transformation and relational-structure schemes for visual pattern recognition
1979
Biological cybernetics
Preserved Fulltext
Two models for visual pattern recognition are described ; the one based on application of internal compensatory transformations to pattern representations, the other based on encoding of patterns in terms ...
These transformation and relational-structure models are each endowed with the same experimentally observed invariance properties, which include independence to pattern translation and pattern jitter, ...
