Abstract : The report extends the two-dimensional method of moments for pictorial pattern recognition to the identification of three-dimensional objects from optical images. The identification is independent of object position or orientation in three-dimensional space. The method developed is applied in an experimental system using a television camera and a computer for obtaining and processing live images of model airplanes. In a six class problem in which the same images were presented to human observers and to the computer, the computer error rate was approximately five percent while the human rate was ten percent. The errors in both cases were due primarily to low resolution and noise in the optical system. (Author)
