Numerically efficient angle, width, offset, and discontinuity determination of straight lines by the discrete Fourier-bilinear transformation algorithm.
We introduce a new method for determining the number of straight lines, line angles, offsets, widths, and discontinuities in complicated images. In this method, line angles are obtained by searching the peaks of a hybrid discrete Fourier and bilinear transformed line angle spectrum. Numerical advantages and performance are demonstrated.
