Hey,
You may refer the following MATLAB answer thread to learn about applying chebyshev type I low pass filter to filter an image.
To apply a Chebyshev Type I low-pass filter to an image in MATLAB, define the filter specifications and use the "cheby1" function to design the filter. Then, read the image, convert it to double precision, and apply the filter to reduce high-frequency components.
If this does not reoslve your query, and you need to apply some other filter, please elaborate on your 'own' filter.
