Webh = fspecial(type) h = fspecial(type, parameters) where 'type' specifies the filter type, and parameters further define the specified filter. The spatial filters supported by fspecial are summarized in Table 1, including applicable parameters for each filter. h = fspecial('average', hsize) returns an averaging filter h of size hsize.

http://www.iotword.com/6562.html Webh = fspecial('disk', radius) returns a circular averaging filter (pillbox) within the square matrix of size 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). black white swirl lollipops

Webh = fspecial(type) creates a two-dimensional filter h of the specified type. Some of the filter types have optional additional parameters, shown in the following syntaxes. fspecial returns h as a correlation kernel, which is the appropriate form to use with imfilter. WebJun 19, 2013 · @ali_m I don't quite understand this line h[ h < np.finfo(h.dtype).eps*h.max() ] = 0 I took a look at the docs and it seems to prevent machine limit errors(?). Is the d.type argument necessary? And why do you use .eps and multiply it with h.max.
