ImageMorph Module

The ImageMorph module provides morphology operations on images.

• class PIL.ImageMorph.LutBuilder(patterns=None, op_name=None)[源代码]
• 基类：object

A class for building a MorphLut from a descriptive language

The input patterns is a list of a strings sequences like these:

4:(...
   .1.
   111)->1

(whitespaces including linebreaks are ignored). The option 4describes a series of symmetry operations (in this case a4-rotation), the pattern is described by:

• . or X - Ignore
• 1 - Pixel is on
• 0 - Pixel is off
  The result of the operation is described after “->” string.

The default is to return the current pixel value, which isreturned if no other match is found.

Operations:

• 4 - 4 way rotation
• N - Negate
• 1 - Dummy op for no other operation (an op must always be given)
• M - Mirroring
  Example:

lb = LutBuilder(patterns = ["4:(... .1. 111)->1"])
lut = lb.build_lut()

• addpatterns(_patterns)[源代码]
• build_default_lut()[源代码]
• build_lut()[源代码]
• Compile all patterns into a morphology lut.

TBD :Build based on (file) morphlut:modify_lut

• get_lut()[源代码]

• class PIL.ImageMorph.MorphOp(lut=None, op_name=None, patterns=None)[源代码]
• 基类：object

A class for binary morphological operators

• apply(image)[源代码]
• Run a single morphological operation on an image

Returns a tuple of the number of changed pixels and themorphed image

• geton_pixels(_image)[源代码]
• Get a list of all turned on pixels in a binary image

Returns a list of tuples of (x,y) coordinatesof all matching pixels.

• loadlut(_filename)[源代码]

• Load an operator from an mrl file

• match(image)[源代码]

• Get a list of coordinates matching the morphological operation onan image.

Returns a list of tuples of (x,y) coordinatesof all matching pixels.

• savelut(_filename)[源代码]

• Save an operator to an mrl file

• setlut(_lut)[源代码]

• Set the lut from an external source
