ABSTRACT:
A machine for detecting image corners in two-dimensional images. The machine transforms two-dimensional images by means of the Haar transform into the two-dimensional Haar transform domain. Certain of the Haar transform coefficients, which are sensitive to corners, are compared to a threshold and an output indicative of a corner is generated whenever a corner sensitive transform coefficient exceeds the threshold.
