Multiscale Handwriting Characterization for Writers' Classification
نویسندگان
چکیده
In this paper, we propose a method for handwritten text characterization based on a multiscale and multiresolution drawing analysis. The approach lies on the definition of four complementary handwritten text visual dimensions: the macro and micro orientation (obtained with a frequencies multiscale image analysis), the text linearity (defined by the merge of connected components), the curvature (measured as a multiresolution high profile deformation) and the complexity (expressed as multiscale drawing distribution entropy). Each feature is studied in an evolution graph that can be expressed as a unique handwritten curve signature. It leads to a description in separable writers families having individual visual characteristics. The results are very promising.

On-line cursive handwriting characterization using TF-IDF scores of graphemes
In this paper, we present an approach for characterizing the on-line cursive handwriting of different writers, which may consist in identifying the writer or his handwriting style. This method is inspired from information retrieval methods and is designed to be embedded in an adaptive word recognizer. We perform experiments assessing the effectiveness of the proposed method for writer identific...
متن کاملRelationship between Handwriting Legibility and Speed and Perceptual-Motor Skills in Persian language Students
The purpose of this inquiry was to examine the interrelations among handwriting legibility and speed, and underlying perceptual-motor skills in Persian language students. Seventy students (26 male, 44 female; 10.21 ± 1.02 yr; 30 poor and 40 good control hand writers) were assessed during a copying task. The children completed the visual-motor control (VMC), upper-limb speed and dexterity (ULSD)...
