Stroke Extraction from Gray-Scale Character Image
نویسندگان
چکیده
In this paper, a topographic feature classification method based on 4directional scanning, and a stroke extraction method from skeletal pixels are proposed. Combination of the proposed methods is relatively fast and the resulting strokes are more acceptable.

Stroke-model-based character extraction from gray-level document images
Global gray-level thresholding techniques such as Otsu's method, and local gray-level thresholding techniques such as edge-based segmentation or the adaptive thresholding method are powerful in extracting character objects from simple or slowly varying backgrounds. However, they are found to be insufficient when the backgrounds include sharply varying contours or fonts in different sizes. A str...
متن کاملCharacter Extraction from Gray Images Based on Mathematical Morphology
A morphology-based thresholding technique for character extraction from outdoor images is developed. Such extraction is traditionally difficult because of the influence of illumination changes, such as lightness, shadow, and reflection. Changes in character font, apparent size, and inclination also make extraction more difficult. Though there are some character reading systems for format and si...

Common tasks in document analysis, such as binarization, line extraction etc., are still considered difficult for highly degraded text documents. Having reliable fundamental information regarding the characters of the document, such as the distribution of character dimensions and stroke width, can significantly improve the performance of these tasks. We introduce a novel perspective of the imag...

Off-line character recognition – Off-line character recognition takes a raster image from a scanner (scanned images of the paper documents), digital camera or other digital input sources. The image is binarised based on for instance, color pattern (color or gray scale) so that the image pixels are either 1 or 0. On-line character recognition – In on-line, the current information is presented to...

Text extraction from image is one of the complicated areas in digital image processing. Text characters entrenched in image represents a rich source of information for text retrieval application. It is a complex process to detect and recognize the text from comic image due to their various size, gray scale values, complex backgrounds and different styles of font. Text extraction process from co...
