PT Journal AU Ernest Valveny Enric Marti TI A model for image generation and symbol recognition through the deformation of lineal shapes SO Pattern Recognition Letters JI PRL PY 2003 BP 2857 EP 2867 VL 24 IS 15 DI 10.1016/S0167-8655(03)00144-2 AB We describe a general framework for the recognition of distorted images of lineal shapes, which relies on three items: a model to represent lineal shapes and their deformations, a model for the generation of distorted binary images and the combination of both models in a common probabilistic framework, where the generation of deformations is related to an internal energy, and the generation of binary images to an external energy. Then, recognition consists in the minimization of a global energy function, performed by using the EM algorithm. This general framework has been applied to the recognition of hand-drawn lineal symbols in graphic documents. PI New York, NY, USA ER
