Morphological degradation models and their use in document image restoration
Document images undergo various degradation processes. Numerous models of these degradation processes have been proposed in the literature. In this paper we propose a modelbased restoration algorithm. The restoration algorithm first estimates the parameters of a degradation model and then uses the estimated parameters to construct a lookup table for restoring the degraded image. The estimated d...
متن کاملOptimal Structuring Elements for the Morphological Pattern Restoration of Binary Images
AbstructIn this paper, we derive the optimal structuring elements of morphological filters in image restoration. The expected pattern transformation of random sets is presented. An estimation theory framework for random sets is subsequently proposed. This framework is based on the least mean difference (LMD) estimator. The least mean difference (LMD) estimator is defined to minimize the cardina...

متن کاملA Downhill Simplex Algorithm for Estimating Morphological Degradation Model Parameters Tapas Kanungo and Qigong Zheng A Downhill Simplex Algorithm for Estimating Morphological Degradation Model Parameters
Noise models are crucial for designing image restoration algorithms, generating synthetic training data, and predicting algorithm performance. However, to accomplish any of these tasks, an estimate of the degradation model parameters is essential. In this paper we describe a parameter estimation algorithm for a morphological, binary image degradation model. The inputs to the estimation algorith...
