Robust extraction of characters from color scene image using mathematical morphology
نویسندگان
چکیده
Current character extraction systems for scene images are not robust for most real-world applications. In contrast, the system present here achieves robust performance by using morphological segmentation. This paper describes a new morphological segmentation algorithm { Di erential Top-hats (DTT). In addition, a complete system for extraction of characters from color scene images is presented. The system was veri ed through experiments on sequences of outdoor color images with varying external conditions. A high average extraction rate of 95% is obtained.

The Extraction of Characters from Scene Image Using Mathematical Morphology
In understanding an image, the extraction of charcters existing in the image is considered to be important. Scene images are differ from document images, which are composed of characters and complicated background (i.e.photo, picture, or painting etc.) instead of white one, this make it difficult to be dealt with. In this paper, we introduce a new method t o extract characters from scene images...
متن کاملSegmentation of Road Guidance Sign Symbols and Characters Based on Normalized RGB Chromaticity Diagram
In this paper, we describe a color segmentation based on the normalized RGB chromaticity diagram to extract the symbols and characters of road guidance signs. The proposed method separates blue color of the signs by utilizing the developed histogram on the normalized RGB chromaticity diagram for selecting the threshold automatically. The image morphology operator and the histogram projection te...
متن کاملAutomated Extraction of Text from Images using Morphology Based Approach
Existing text strings play an important role in understanding a scene image. Scene images differ from document images, which are composed of text characters of various size, shape, direction, and situation along with complicated backgrounds, such as map, picture or painting, etc. Hence, the extraction of texts on scene images is a difficult as well as challenging task. Mathematical morphology b...

We developed a robust color segmentation system adapted for invoices and forms with significant color complexity and dithered background. The system achieves several...
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...
