Shock Filters for Character Image Enhancement and Peeling
In this paper, we propose a generalized shock model for the enhancement and restoration of degraded gray-level character images. This model is a quasi-linear hyperbolic partial di...

Coherence-Enhancing Shock Filters
Shock filters are based in the idea to apply locally either a dilation or an erosion process, depending on whether the pixel belongs to the influence zone of a maximum or a minim...

Text Enhancement with Asymmetric Filter for Video OCR
Stripes are common sub-structures of text characters, and the scale of these stripes varies little within a word. This scale consistency thus provides us with a useful feature for...

A Robust Split-and-Merge Text Segmentation Approach for Images
In this paper we describe a robust approach to segment text from color images. The proposed approach mainly includes four steps. Firstly, a preprocessing step is utilized to enhan...
