Connective Hough Transform

Shiu Yin K. Yuen

A method to extend the Hough transform (HT) to detect connectivity by ordered accumulation is reported. The method is applied to the dynamic combinatorial HT. A focus of attention mechanism is also reported. Our connective HT with focus of attention reduces the computational complexity of the DCHT and increases the S/N ratio of the peak in its accumulator. It may be regarded as a principled method for curve tracing. A general method to improve the computational efficiency of the DCHT by probabilistic selection of interesting fixation points is also introduced. Results using simulated and real data are reported.
