Changes in lighting and the effects of perspective also pose no problems. How do we achieve this, and more importantly, how can we get a computer to do this? One very promising approach is to find mathematical functions of an object's image, or of an object's 3D description, that are invariant to the transformations caused by the object's motion. This book is devoted to the theory and practice of such invariant image features, so-called image invariants, for planar objects. It gives a comprehensive summary of the field, discussing methods for recognizing both occluded and partially occluded objects, and also contains a definitive treatmentof moment invariants and a tutorial introduction to algebraic invariants, which are fundamental to affine moment invariants and to many projective invariants. A number of novel invariant functions are presented and the results of numerous experiments investigating the stability of new and old invariants are discussed. The main conclusion is that moment invariants are very effective, both for partially occluded objects and for recognizing objects in grey-level images. 410 0$aLecture Notes in Computer Science,$x0302-9743 ;$v676 606 $aComputer graphics 606 $aOptical data processing 606 $aPattern recognition 606 $aGeometry 606 $aComputer Graphics$3https://scigraph.springernature.com/ontologies/product-market-codes/I22013 606 $aImage Processing and Computer Vision$3https://scigraph.springernature.com/ontologies/product-market-codes/I22021 606 $aPattern Recognition$3https://scigraph.springernature.com/ontologies/product-market-codes/I2203X 606 $aGeometry$3https://scigraph.springernature.com/ontologies/product-market-codes/M21006 615 0$aComputer graphics. 615 0$aOptical data processing. 615 0$aPattern recognition. 615 0$aGeometry. 615 14$aComputer Graphics. 615 24$aImage Processing and Computer Vision. 615 24$aPattern Recognition. 615 24$aGeometry. 676 $a006.4/2 700 $aReiss$b Thomas H$4aut$4http://id.loc.gov/vocabulary/relators/aut$0714560 906 $aBOOK 912 $a996466083603316 996 $aRecognizing planar objects using invariant image features$91381885 997 $aUNISA
