Abstract
In order to restore the color of original monochrome image which obtained from Charge-Coupled Device (CCD) directly, we design a Bayer mode color filter array start with specific pixels to satisfy the imaging condition and then we use bilinear interpolation algorithm to restore the color of original monochrome image which formatted by Y800, however, the hues of adjacent pixels change abruptly by the bilinear interpolation, therefore, we use smooth hue transition interpolation to enhance the edge of original image and finally we identify the ultimate performance of these interpolation algorithms by magnified the interpolated image and use mean square error to compare these algorithms, the results show that the smooth hue transition interpolation is better than bilinear interpolation for color restoration of monochrome image.
Keywords:
