A scheme for recognizing 3D objects from single 2D images under orthographic projection is introduced. The scheme proceeds in two stages. In the first stage, the categorization stage, the image is com... / methods for reducing the computational complexity of the recognition br a way to reduce this computational complexity. The objective of

18   On- And Off-Line Identification Of Linear State Space Models - Moonen, De Moor, Vandenberghe.. (1989)   (Correct)
A geometrically inspired matrix algorithm is derived for the identification of state space models for multivariable linear time-invariant systems using (possibly noisy) input-output measurements only.... / so far mostly due to the computational complexity involved Ho and Kalman
