Matlab Conv2 Mean Filter, MATLAB allows us to create custom filters using functions like fspecial () or use pre-defined filters such as Gaussian, Laplacian, or This MATLAB function returns the two-dimensional convolution of matrices A and B. A 2-D convolutional layer applies sliding convolutional filters to 2-D input. Types of filters conv2 outputs the entire 2-D convolution, which means that yconv2 will be bigger than mypic. Because correlation and convolution are related, observe that you can get the same result by filtering the entire image using 7x7 arithmetic mean filter. The function filter2 performs two-dimensional Reduce the image noise by implementing a mean filter window of size 9 (a 3x3 averaging window).
