Abstract:
A method to be used with a digital imaging system to facilitate magnification of a region of interest on an initial digital image wherein the region of interest includes a plurality of pixels of interest, adjacent portions of adjacent pixels of interest forming interpixel intervals of interest, each pixel of interest characterized by a pixel intensity, the system including convolution filter and interpolation hardware, the method comprising the steps of:(A) for each interpixel interval of interest, identifying adjacent pixels;(B) for each adjacent pixel:(i) selecting a convolution window and, for each window:(a) determining a convolution filter coefficient for each window pixel;(b) convoluting the intensities of the pixels in the window as a function of the coefficients to generate an intermediate value; and(ii) interpolating the intermediate values to generate at least two interpolated pixel intensities, the interpolated pixel intensities together forming an interpolated image.
