For example, you can filter an image to emphasize certain features or remove other features. Image processing operations implemented with filtering include smoothing, sharpening, and edge enhancement. Matlab – Spatial Filtering Filtering is a technique for modifying or enhancing an image. As it name stated, spatial filtering use filter or also know as mask, kernel, template or window.

Filtering is a technique for modifying or enhancing an image. For example, you can filter an image to emphasize certain features or remove other features. Image processing operations implemented with filtering include smoothing, sharpening, and edge enhancement. Spatial filtering is a technique that uses a pixel and its neighbors to select a new value for the pixel. The simplest type of spatial filtering is called linear filtering. You can define the filters for spatial filtering manually or you can call a function that will create the filter matrices. The function, called fspecial, requires an argument that specifies the kind of filter you would like.

function out = spatial_filter(img,h) [m,n] = size(h); [x,y] = size(img); a = (m-1)/2; b = (n-1)/2; g = zeros(x+a+1, y+b+1); %zero pad for i=1:x for j=1:y g(i+a,j+b) = img(i,j); end end 2013-06-25 In spatial filtering, it is desirable to have the size of the output and input images equal, because that allows further algebraic operations such as discussed at the beginning of this chapter.If a W × W window (W being an odd integer) is used for a convolution filter, the border region includes the first and last W/2 (truncated to an integer) rows and columns of the input image (Fig. 6-6).
