Butterworth Bandpass Filter
This simple function was written for my Digital Image Processing course
at Eastern Mediterranean University taught by
Assoc. Prof. Dr. Hasan Demirel
for the 2010-2011 Spring Semester

I = The input grey scale image
d0 = Lower cut off frequency
d1 = Higher cut off frequency
The function makes use of the simple principle that a bandpass filter
can be obtained by multiplying a lowpass filter with a highpass filter
where the lowpass filter has a higher cut off frquency than the high pass filter.
ima = imread('grass.jpg');
ima = rgb2gray(ima);
filtered_image = gaussianbpf(ima,30,120);
