Generalizing the Hough transform to detect arbitrary shapes
-The Hough transform is a method for "~.~tecting curves by exploiting the duality between points on a curve and parameters of that curve. The initial work showed how to detect both analytic curves (1'2) and non-analytic curves, (3) but these methods were restricted to binary edge images. This work was generalized to the detection of some analytic curves in grey level images, specifically lines,...

متن کاملInvariant Characterization of the Hough Transform for Pose Estimation of Arbitrary Shapes
We develop a new formulation for including invariance in a general form of the Hough transform. We first develop a formal definition of the Hough transform mapping for arbitrary shapes and general transformations. We then include an invariant characterization of shapes and we develop and apply our technique to extract shapes under similarity and affine transformations. Our characterization does...
متن کاملA Fast Randomized Generalized Hough Transform for Arbitrary Shape Detection
The well-known arbitrary shape detection technology, generalized Hough transform (GHT) has the drawbacks of heavy computations (one-to-many or 1-to-n mapping) and storage requirements (voting space and entry number). Some n-to-1 mapping approaches have been proposed for improving the performance of GHT, such as the FGHT (fast generalized Hough transform), ADPHT (Adaptive dual-point Hough transf...
