Abstract
- There are various ways to binarize images automatically. Our study is how to binarize character images which were taken under bad lighting conditions with CCD camera. We propose a linear equation for threshold and the adaptive image segmentation. The dynamic thresholding by this method makes these shading images well binarized in quality.
