H = FSPECIAL(TYPE) creates a two-dimensional filter H of the specified type. Possible values for TYPE are: 'average' averaging filter 'disk' circular averaging filter 'gaussian' Gaussian lowpass filter 'laplacian' filter approximating the 2-D Laplacian operator 'log' Laplacian of Gaussian filter 'motion' motion filter 'prewitt' Prewitt horizontal edge-emphasizing filter 'sobel' Sobel horizontal edge-emphasizing filter 'unsharp' unsharp contrast enhancement filter Depending on TYPE, FSPECIAL may take additional parameters which you can supply. These parameters all have default values. H = FSPECIAL('average',HSIZE) returns an averaging filter H of size HSIZE. HSIZE can be a vector specifying the number of rows and columns in H or a scalar, in which case H is a square matrix. The default HSIZE is [3 3]. H = FSPECIAL('disk',RADIUS) returns a circular averaging filter (pillbox) within the square matrix of side 2*RADIUS+1. The default RADIUS is 5. H = FSPECIAL('gaussian',HSIZE,SIGMA) returns a rotationally symmetric Gaussian lowpass filter of size HSIZE with standard deviation SIGMA (positive). HSIZE can be a vector specifying the number of rows and columns in H or a scalar, in which case H is a square matrix. The default HSIZE is [3 3], the default SIGMA is 0.5. H = FSPECIAL('laplacian',ALPHA) returns a 3-by-3 filter approximating the shape of the two-dimensional Laplacian operator. The parameter ALPHA controls the shape of the Laplacian and must be in the range 0.0 to 1.0. The default ALPHA is 0.2. H = FSPECIAL('log',HSIZE,SIGMA) returns a rotationally symmetric Laplacian of Gaussian filter of size HSIZE with standard deviation SIGMA (positive). HSIZE can be a vector specifying the number of rows and columns in H or a scalar, in which case H is a square matrix. The default HSIZE is [5 5], the default SIGMA is 0.5. H = FSPECIAL('motion',LEN,THETA) returns a filter to approximate, once convolved with an image, the linear motion of a camera by LEN pixels, with an angle of THETA degrees in a counter-clockwise direction. The filter becomes a vector for horizontal and vertical motions. The default LEN is 9, the default THETA is 0, which corresponds to a horizontal motion of 9 pixels. H = FSPECIAL('prewitt') returns 3-by-3 filter that emphasizes horizontal edges by approximating a vertical gradient. If you need to emphasize vertical edges, transpose the filter H: H'. [1 1 1;0 0 0;-1 -1 -1]. H = FSPECIAL('sobel') returns 3-by-3 filter that emphasizes horizontal edges utilizing the smoothing effect by approximating a vertical gradient. If you need to emphasize vertical edges, transpose the filter H: H'. [1 2 1;0 0 0;-1 -2 -1]. H = FSPECIAL('unsharp',ALPHA) returns a 3-by-3 unsharp contrast enhancement filter. FSPECIAL creates the unsharp filter from the negative of the Laplacian filter with parameter ALPHA. ALPHA controls the shape of the Laplacian and must be in the range 0.0 to 1.0. The default ALPHA is 0.2. Class Support ------------- H is of class double. Example ------- I = imread('saturn.tif'); subplot(2,2,1);imshow(I);title('Original Image'); H = fspecial('motion',50,45); MotionBlur = imfilter(I,H); subplot(2,2,2);imshow(MotionBlur);title('Motion Blurred Image'); H = fspecial('disk',10); blurred = imfilter(I,H); subplot(2,2,3);imshow(blurred);title('Blurred Image'); H = fspecial('unsharp'); sharpened = imfilter(I,H); subplot(2,2,4);imshow(sharpened);title('Sharpened Image');
