Outline Activities
The recognition of the line is a very important subject in image understanding by the computer. My research is the recognition method of the line on the basis of the distribution of gradient vectors. This method can recognize the line regardless of the contrast. In addition, we are constructing the computer aided diagnosis system by using this method for medical images.
