Invariant analogical image representation and pattern recognition

Lowell Jacobson, Harry Wechsler
1984 Pattern Recognition Letters  
We describe an image representation that uniquely encodes the information in a gray-scale image. decouples the ef fects of illumination. reflectance. and angle of incidence. and is Invariant. within a linear shift. to perspective. position, orienta tion. and size of arbitrary planar forms, Then we provide a theoretical basis for applying this representation to achieve invariall! form recognition.
