Amplitude-only log Radon transform for geometric invariant shape descriptor

作者：

Highlights：

• We propose a new shape descriptor based on Radon transform

• This descriptor needs no normalizations.

• It is invariant to geometric transformations (rotation scale and translation) and robust to noise.

• The rotation angle, the scaling factor and the position shift can be easily determined.
