ToSet

ToSet[img] returns a set description of binary image img (i.e., the position of all pixels with a value equal to one).

ToSet[img, {r₀, c₀}] returns the positions of all ones in image img with an origin at the position given by {r₀, c₀}.

ToSet[img, {r₀, c₀}, v] returns the position of all pixels equal to v in image img with an origin at the position given by {r₀, c₀}.

The default origin is at position {1, 1} in img.

The argument img may be a list or ImageData expression.

Examples

This loads the package.

In[1]:=

Here is a binary image.

In[2]:=

This returns the default set description of image A.

In[3]:=

Out[3]=

Here we assume that the coordinate center is at position {2, 3} in the array.

In[4]:=

Out[4]=

This will give the complement set.

In[5]:=

Out[5]=
