IMINTERP

Purpose:

Interpolates an image.

IMINTERP(image, factor, method)

image

An array. The input image.

factor

Optional. An integer, the interpolation factor. Defaults to 2.

method

Optional. An integer, the interpolation method:

0:	linear (default)
1:	cubic spline

An array.

W1: readimage(gethome + "data\mandrill.bmp")

W2: iminterp(W1, 4, 0)

W3: iminterp(W1, 4, 1)

W2 produces a linearly interpolated image and W3 contains a cubic spline interpolated image. The both images are interpolated by a factor of 4.

If the image is an RGBIMAGE (i.e. a 24 bit image), IMINTERP automatically interpolates each R, G, B (red, green, blue) component.
