Image Binarization by Dynamic Convex Quadrilateral Region Segmentation Using GA
Autor: Soma Nakamura, Fumihiko Saitoh
Publikováno v: Electronics and Communications in Japan. 99:53-61
The method that binarizes an image by local thresholds in separated image areas is useful when the image has uneven brightness. A method was proposed to separate an image dynamically for local thresholding to generate a binary image by using a geneti

Upgradation of Ultralow-Gradation Images by Using Spatial Features
Autor: Tetsuya Kato, Fumihiko Saitoh
Publikováno v: Electronics and Communications in Japan. 98:53-62
SUMMARY This paper proposes a method that obtains high-tone images from ultra-low-tone image by using spatial features. Areas are smoothed when the adjacent tone value of the area of interest is continuous, but areas are saved as edges when the adjac

Perceptive curve detection by global edge tracing
Autor: Takamitsu Takagi, Fumihiko Saitoh
Publikováno v: Electronics and Communications in Japan. 96:1-14
Human beings have an ability to perceive continuous curves from a binary image that includes discontinuous curves and noise. To achieve this capability, global detection is required. In the past, we have proposed a perceptive curve detection method w
