Projection–Based Text Line Segmentation with a Variable Threshold

A Simple Text-line segmentation Method

Text line segmentation is an important step because inaccurately segmented text lines will cause errors in the recognition stage.. The nature of handwriting makes the process of text line segmentation very challenging. Text characteristics can vary in font, size, orientation, alignment, color, contrast, and background information. These variations turn the process of word detection complex and ...

Handwritten Text Line Segmentation by Clustering with Distance Metric Learning

Separating text lines in handwritten documents remains a challenge because the text lines are often ununiformly skewed and curved. In this paper, we propose a novel text line segmentation algorithm based on Minimal Spanning Tree (MST) clustering with distance metric learning. Given a distance metric, the connected components of document image are grouped into a tree structure. Text lines are ex...

A TaLISMAN: Automatic Text and LIne Segmentation of historical MANuscripts

Historical and artistic handwritten books are valuable cultural heritage (CH) items, as they provide information about tangible and intangible cultural aspects from the past. Massive digitization projects have made these kind of data available to a world-wide population, and pose real challenges for automatic processing. In this scenario, document layout analysis plays a significant role, being...
