Gaussian Bandpass Filter for Image Processing
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.
Usage GAUSSIANBPF(I,DO,D1)
Example
ima = imread('grass.jpg');
ima = rgb2gray(ima);
filtered_image = gaussianbpf(ima,30,120);
