On the optimal detection of curves in noisy pictures

Communications of the ACM, 1971
Abstract : A technique for recognizing systems of lines is presented, in which the heuristic of the problem is not embedded in the recognition algorithm but is expressed in a figure of merit. A multistage decision process is then able to recognize in the input picture the optimal system of lines according to the given figure of merit. Due to the global

Properties of transforms for the detection of curves in noisy pictures

Computer Graphics and Image Processing, 1978
Performance characteristics of Hough-like transforms for curve detection are presented. These results are based on previous work. Included are formulations of the transform method, homogeneity and packing in parameter space, sensitivity, estimation, and determination of required low-level measurement accuracies subject to cost constraints, and changes ...

Reconstruction of Noisy Bezier Curves Using Artificial Neural Networks

2014
The current work examines the reconstruction of Bezier curves with noisy data using artificial neural networks. Feed forward network with back propagation learning is used to fit the noisy data of the Bezier curves. Different parameters like learning rate, number of hidden layer neurons and number of epochs are studied and the results are compared for ...

Curve and surface reconstruction from noisy samples

2014
Reconstructing an unknown curve or surface from sample points is an important task in geometric modeling applications. Sample points obtained from real applications are usually noisy. For example, when data sets are obtained by scanning images in the plane or images in three dimensions.
