Matlab is an interpreted language and looping through a vector like this is the slowest possible way to change a vector. The notation used in the first statement is much faster than the loop. A better example, is one in which we want to perform operations on the rows of a matrix.

Your code for an LP filter is the inverse Fourier transform of an Ideal low-pass filter. So by getting a frequency response for the function you wrote you'll get an ideal LP response you want. However, there are two mistakes: 1) Your frequency for the ideal LP filter needs to be $[-\frac{m-1}{2} : \frac{m-1}{2}]$

Ideal FIR Low Pass Filter without using inbuilt MATLAB function By Creative Engineering Projects on 10:14 in Digital Signal Processing , FIR , LPF , MATLAB %ideal low pass linear phase FIR filter% (b) To use the ifft2() function in MATLAB to recover the original image, you will need to construct a Cartesian FFT from the polar data. Use the interp2() and cart2pol() or pol2cart() functions to create a Cartesian version of the FFT with the same number of pixels as the original image. I want to implement the filter using the multiplication instead using the inbuilt filter fucntion.

medfilt2 supports the generation of C code (requires MATLAB ® Coder™).Note that if you choose the generic MATLAB Host Computer target platform, medfilt2 generates code that uses a precompiled, platform-specific shared library. Use of a shared library preserves performance optimizations but limits the target platforms for which code can be generated.By using the "int" function, in the same way we use the diff function, we can ask Matlab to do symbolic integration for us. Warning: Do not confuse the int function in Matlab with the integer (int) data type in C or the int8, int16, int32 data types in Matlab. >> syms x t; f = x * x ; >>int(f) ans = 1/3*x^3

Please find below a sample Matlab script for applying a geometric mean filter on a gray scale image. The exact operation of the filter can be found in any standard text book on image processing such as Digital Image Processing by Gonzalez and Wood...MATLAB code for Linear filtering without using imfilter function. Linear filtering technique is used for reducing random noise, sharpening the edges and correcting unequal illuminations. The procedure is carried out by filtering the image by correlation with an appropriate filter kernel. Using "sum" as name of a variable leads to errors frequently, when the user wants to use the function with the same name. Therefore it is recommended not to shadow built-in functions. It would be much more useful for others, if the code is written as a function and the parameters and data are provided as input arguments.
