High-Pass Filtering (Sharpening) A high-pass filter can be used to make an image appear sharper. These filters emphasize fine details in the image – exactly the opposite of the low-pass filter. High-pass filtering works in exactly the same way as low-pass filtering; it just uses a different convolution kernel. Gaussian low pass and Gaussian high pass filter minimize the problem that occur in ideal low pass and high pass filter. This problem is known as ringing effect. This is due to reason because at some points transition between one color to the other cannot be defined precisely, due to which the ringing effect appears at that point.

And I think you don't want to use ‘ones’ and convolution. The low-pass filters usually employ moving window operator which affects one pixel of the image at a time, changing its value by some function of a local region (window) of pixels. The operator moves over the image to affect all the pixels in the image. Other common design methods for low-pass FIR-based filters include Kaiser window, least squares, and equiripple. Design methods for IIR-based filters include Butterworth, Chebyshev (Type-I and Type-II), and elliptic. For more information on filter design, including these methods, see Signal Processing Toolbox™ for use with MATLAB ®. May 04, 2012 · A "simple" low-pass filter will never have a sharp cut-off at a particular frequency, especially not if it has to be a "streaming" filter. If you do not have any time constraints then you can use the more complex filtering of fft, zeroing coefficients, fft back.

I'm having trouble figuring out how to pass a signal into a low pass filter using MATLAB. I am given a .wav file and am following instructions on how to remove high frequency noise compenents from taking the Discrete Fourier Transform(DFT) of the audio signal. The filter equation is designed for Low pass FIR filter of order '50'.The 'k' value is starting from 55 because the original input signal is starting from 55th location in MATLAB and ends uptill 1077th location.
