Pattern classification and clustering: a review of partially supervised learning approaches
Schwenker F., Trentin E. Pattern Recognition Letters 374-14, 2014. Type: Article
Building efficient classifiers for supervised machine learning is a must for many applications, ranging from automatic recommendation to network intrusion detection. Similarly, clusters developed in an unsupervised learning framework a...

Image thresholding based on semivariance
Beauchemin M. Pattern Recognition Letters 34(5): 456-462, 2013. Type: Article
Thresholding is a method of separating an image into background and foreground objects. Beauchemin presents a semivariance-based thresholding method to binarize black-and-white images. The author uses variograms, typically used in stat...

A combined approach for the binarization of handwritten document images
Ntirogiannis K., Gatos B., Pratikakis I. Pattern Recognition Letters 353-15, 2014. Type: Article
The authors of this paper combine global and local methods for detecting faint characters, bleed-through, and large background ink stains, and propose an adaptive document image binarization method applied at the connected component le...

A new approach to estimate lacunarity of texture images
Backes A. Pattern Recognition Letters 34(13): 1455-1461, 2013. Type: Article
Two new methods for discriminating textures in images, based on the estimation of texture image lacunarity, are proposed in this paper. The concept of lacunarity was introduced by Mandelbrot and “describes the texture pattern...

Vague C-means clustering algorithm
Xu C., Zhang P., Li B., Wu D., Fan H. Pattern Recognition Letters 34(5): 505-510, 2013. Type: Article
Clustering data into fuzzy or vague categories is an essential task for data mining and information retrieval applications. In this paper, the authors propose adapting the classical fuzzy C-means (FCM) algorithm to vague sets, an exten...

A study on the consistency and significance of local features in off-line signature verification
Kovari B., Charaf H. Pattern Recognition Letters 34(3): 247-255, 2013. Type: Article
Online and off-line, automatic signature verification has been an active research topic for decades. Given carefully designed features and curated data, we usually see satisfactory performance, with reductions in equal error rate (EER)...
