IMFILTER Multidimensional image filtering.
B = IMFILTER(A,H) filters the multidimensional array A with the
multidimensional filter H. A can be a nonsparse numeric array of any
class and dimension. The result, B, has the same size and class as
A.
Each element of the output, B, is computed using double-precision
floating point. If A is an integer array, then output elements that
exceed the range of the integer type are truncated, and fractional
values are rounded.
B = IMFILTER(A,H,OPTION1,OPTION2,...) performs multidimensional
filtering according to the specified options. Option arguments can
have the following values:
- Boundary options
X Input array values outside the bounds of the array
are implicitly assumed to have the value X. When no
boundary option is specified, IMFILTER uses X = 0.
'symmetric' Input array values outside the bounds of the array
are computed by mirror-reflecting the array across
the array border.
'replicate' Input array values outside the bounds of the array
are assumed to equal the nearest array border
value.
'circular' Input array values outside the bounds of the array
are computed by implicitly assuming the input array
is periodic.
- Output size options
(Output size options for IMFILTER are analogous to the SHAPE option
in the functions CONV2 and FILTER2.)
'same' The output array is the same size as the input
array. This is the default behavior when no output
size options are specified.
'full' The output array is the full filtered result, and so
is larger than the input array.
- Correlation and convolution
'corr' IMFILTER performs multidimensional filtering using
correlation, which is the same way that FILTER2
performs filtering. When no correlation or
convolution option is specified, IMFILTER uses
correlation.
'conv' IMFILTER performs multidimensional filtering using
convolution.
Example
-------------
rgb = imread('flowers.tif');
h = fspecial('motion',50,45);
rgb2 = imfilter(rgb,h);
imshow(rgb), title('Original')
figure, imshow(rgb2), title('Filtered')
rgb3 = imfilter(rgb,h,'replicate');
figure, imshow(rgb3), title('Filtered with boundary replication')
