+ * This function resizes the given input image.

+ * a) ICV_RESIZE_UNDERSAMPLE : This method undersamples the said image
+ * eg. icv_resize(bif, ICV_RESIZE_UNDERSAMPLE, 0, 0, 2);
+ * undersamples the image with a factor of 2.
+ *
+ * b) ICV_RESIZE_SHRINK : This Shrinks the image, keeping the light
+ * energy per square area as constant.
+ * eg. icv_resize(bif, ICV_RESIZE_SHRINK,0,0,2); shrinks the image
+ * with a factor of 2.
+ *
+ * c) ICV_RESIZE_NITERP : This interpolates using nearest neighbour
+ * method.
+ * eg. icv_resize(bif, ICV_RESIZE_NITERP,1024,1024,0);
+ * Interpolates the output image to have the size of 1024X1024.
