A novel algorithm for image space resolution enhancement

Based on the balance theory of static electric field and CCD image forming features, the internal principle of image forming is analyzed. A new algorithm for image space resolution enhancement is presented. With this algorithm, the interpolation function can be adjusted automatically with electrical potential difference of the adjoining pixels and its energy zone, by means of which, the image can be magnified self-adaptively. Particularly, this algorithm takes into consideration of the effects of each color vector on image´s interpolation. Therefore, marginal vagueness, keystone distortion and distinct artifacts brought by traditional methods are overcome, and color distortion brought by separate disposal of the color individually is also mitigated. Gray image and color image are tested separately, and the test results show that with not only the image quality is improved, but also clear margin and contour information is kept with this algorithm.
