The developed method is a statistical approach, where all possible patterns included in a pixel mask are processed in order to extract indexes that characterize the image. Then these indexes are used to classify a query drop cap by searchi

Comparing Graph Similarity Measures for Graphical Recognition,nts are used including line drawings (symbols), ancient documents (ornamental letters), shapes and trademark-logos. The experimental results show that the performance of each graph distance measure depends on the kind of data and the graph representation technique.

Robust and Precise Circular Arc Detection,le of assessing the quality of its detection. It is based on Random Sample Consensus minimization, and uses techniques that are inspired from object tracking in image sequences. It is based on simple initial guesses, either based on connected line segments, or on elementary mainstream arc detection

The median-shift is an iterative process which shifts each data point to the “median” point of its neighborhood defined thanks to a distance measure and a maximum radius, the only parameter of the method. The process is viewed as a graph transformation which converges to a set of clusters

Detection of Circular Arcs in a Digital Image Using Chord and Sagitta Properties,an circle can be used to detect a digital circle or a circular arc. Based on this property, digital circular arcs are first extracted and then using the ., their centers and radii are computed. Several arcs are merged together to form a complete digital circle or a larger arc. Finally, a technique b

GOAL: Towards Understanding of Graphic Objects from Architectural to Line Drawings,ic information in a document image may be present in several forms, such as engineering drawings, architectural plans, musical scores, tables, charts, extended objects, hand-drawn sketches, etc. There exist quite a few approaches for segmentation of graphics from text, and also a separate set of tec
