Modified Hausdorff Fractal Dimension (MHFD)
Reza Farrahi Moghaddam, Mohamed Cheriet
The Hausdorff fractal dimension has been a fast-to-calculate method to estimate complexity of fractal shapes. In this work, a modified version of this fractal dimension is presente…
Spiralet Sparse Representation
Reza Farrahi Moghaddam, Mohamed Cheriet
This is the first report on Working Paper WP-RFM-14-01. The potential and capability of sparse representations is well-known. However, their (multivariate variable) vectorial form,…
A maximal-information color to gray conversion method for document images: Toward an optimal grayscale representation for document image binarization
Reza Farrahi Moghaddam, Shaohua Chen, Rachid Hedjam +1
A novel method to convert color/multi-spectral images to gray-level images is introduced to increase the performance of document binarization methods. The method uses the distribut…
Unsupervised ensemble of experts (EoE) framework for automatic binarization of document images
Reza Farrahi Moghaddam, Fereydoun Farrahi Moghaddam, Mohamed Cheriet
In recent years, a large number of binarization methods have been developed, with varying performance generalization and strength against different benchmarks. In this work, to lev…
A prototype system for handwritten sub-word recognition: Toward Arabic-manuscript transliteration
Reza Farrahi Moghaddam, Mohamed Cheriet, Thomas Milo +1
A prototype system for the transliteration of diacritics-less Arabic manuscripts at the sub-word or part of Arabic word (PAW) level is developed. The system is able to read sub-wor…
Beyond pixels and regions: A non local patch means (NLPM) method for content-level restoration, enhancement, and reconstruction of degraded document images
Reza Farrahi Moghaddam, Mohamed Cheriet
A patch-based non-local restoration and reconstruction method for preprocessing degraded document images is introduced. The method collects relative data from the whole input image…
