"""" ========================================================= Gaussian Processes regression: basic introductory example ========================================================= A simple one-dimensional regression example computed in two different ways: 1. A noise-free case 2. A noisy case with known noise-level per datapoint In both cases, the kernel's parameters are estimated using the maximum likelihood principle. The figures illustrate the interpolating property of the Gaussian Process model as well as its probabilistic nature in the form of a pointwise 95% confidence interval. Note that the parameter ``alpha`` is applied as a Tikhonov regularization of the assumed covariance between the training points.

"# -*- coding: utf-8 -*- """ Sphinx directive to support embedded IPython code. This directive allows pasting of entire interactive IPython sessions, prompts and all, and their code will actually get re-executed at doc build time, with all prompts renumbered sequentially. It also allows you to input code as a pure python input by giving the argument python to the directive. The output looks like an interactive ipython section. To enable this directive, simply list it in your Sphinx ``conf.py`` file (making sure the directory where you placed it is visible to sphinx, as is needed for all Sphinx directives). For example, to enable syntax highlighting and the IPython directive:: extensions = ['IPython.sphinxext.ipython_console_highlighting', 'IPython.sphinxext.ipython_directive'] The IPython directive outputs code-blocks with the language 'ipython'. So if you do not have the syntax highlighting extension enabled as well, then all rendered code-blocks will be uncolored. By default this directive assumes that your prompts are unchanged IPython ones, but this can be customized. The configurable options that can be placed in conf.py are: ipython_savefig_dir: The directory in which to save the figures. This is relative to the Sphinx source directory. The default is `html_static_path`. ipython_rgxin: The compiled regular expression to denote the start of IPython input lines. The default is re.compile('In \[(\d+)\]:\s?(.*)\s*'). You shouldn't need to change this. ipython_rgxout: The compiled regular expression to denote the start of IPython output lines. The default is re.compile('Out\[(\d+)\]:\s?(.*)\s*'). You shouldn't need to change this. ipython_promptin: The string to represent the IPython input prompt in the generated ReST. The default is 'In [%d]:'. This expects that the line numbers are used in the prompt. ipython_promptout: The string to represent the IPython prompt in the generated ReST. The default is 'Out [%d]:'. This expects that the line numbers are used in the prompt. ipython_mplbackend: The string which specifies if the embedded Sphinx shell should import Matplotlib and set the backend. The value specifies a backend that is passed to `matplotlib.use()` before any lines in `ipython_execlines` are executed. If not specified in conf.py, then the default value of 'agg' is used. To use the IPython directive without matplotlib as a dependency, set the value to `None`. It may end up that matplotlib is still imported if the user specifies so in `ipython_execlines` or makes use of the @savefig pseudo decorator. ipython_execlines: A list of strings to be exec'd in the embedded Sphinx shell. Typical usage is to make certain packages always available. Set this to an empty list if you wish to have no imports always available. If specified in conf.py as `None`, then it has the effect of making no imports available. If omitted from conf.py altogether, then the default value of ['import numpy as np', 'import matplotlib.pyplot as plt'] is used. ipython_holdcount When the @suppress pseudo-decorator is used, the execution count can be incremented or not. The default behavior is to hold the execution count, corresponding to a value of `True`. Set this to `False` to increment the execution count after each suppressed command. As an example, to use the IPython directive when `matplotlib` is not available, one sets the backend to `None`:: ipython_mplbackend = None An example usage of the directive is: .. code-block:: rst .. ipython:: In [1]: x = 1 In [2]: y = x**2 In [3]: print(y) See http://matplotlib.org/sampledoc/ipython_directive.html for additional documentation.

"""" ======================= Morphological Filtering ======================= Morphological image processing is a collection of non-linear operations related to the shape or morphology of features in an image, such as boundaries, skeletons, etc. In any given technique, we probe an image with a small shape or template called a structuring element, which defines the region of interest or neighborhood around a pixel. In this document we outline the following basic morphological operations: 1. Erosion 2. Dilation 3. Opening 4. Closing 5. White Tophat 6. Black Tophat 7. Skeletonize 8.

To illustrate this more clearly, let's add a small crack to the white border: """ phantom = img_as_ubyte(io.imread(data_dir+'/phantom.png', as_grey=True)) phantom[10:30, 200:210] = 0 closed = closing(phantom, selem) plot_comparison(phantom, closed, 'closing') """ .. image:: PLOT2RST.current_figure Since ``closing`` an image starts with an dilation operation, dark regions that are *smaller* than the structuring element are removed. The dilation operation that follows ensures that dark regions that are *larger* than the structuring element retain their original size. Notice how the white ellipses at the bottom get connected because of dilation, but other dark region retain their original sizes. Also notice how the crack we added is mostly removed. White tophat ============ The ``white_tophat`` of an image is defined as the *image minus its morphological opening*. This operation returns the bright spots of the image that are smaller than the structuring element. To make things interesting, we'll add bright and dark spots to the image: """ phantom = img_as_ubyte(io.imread(data_dir+'/phantom.png', as_grey=True)) phantom[340:350, 200:210] = 255 phantom[100:110, 200:210] = 0 w_tophat = white_tophat(phantom, selem) plot_comparison(phantom, w_tophat, 'white tophat') """ .. image:: PLOT2RST.current_figure As you can see, the 10-pixel wide white square is highlighted since it is smaller than the structuring element. Also, the thin, white edges around most of the ellipse are retained because they're smaller than the structuring element, but the thicker region at the top disappears. Black tophat ============ The ``black_tophat`` of an image is defined as its morphological **closing minus the original image**. This operation returns the *dark spots of the image that are smaller than the structuring element*. """ b_tophat = black_tophat(phantom, selem) plot_comparison(phantom, b_tophat, 'black tophat') """ .. image:: PLOT2RST.current_figure As you can see, the 10-pixel wide black square is highlighted since it is smaller than the structuring element. Duality ------- As you should have noticed, many of these operations are simply the reverse of another operation. This duality can be summarized as follows: 1. Erosion <-> Dilation 2. Opening <-> Closing 3. White tophat <-> Black tophat Skeletonize =========== Thinning is used to reduce each connected component in a binary image to a *single-pixel wide skeleton*. It is important to note that this is performed on binary images only. """ from skimage import img_as_bool horse = ~img_as_bool(io.imread(data_dir+'/horse.png', as_grey=True)) sk = skeletonize(horse) plot_comparison(horse, sk, 'skeletonize') """ .. image:: PLOT2RST.current_figure As the name suggests, this technique is used to thin the image to 1-pixel wide skeleton by applying thinning successively. Convex hull =========== The ``convex_hull_image`` is the *set of pixels included in the smallest convex polygon that surround all white pixels in the input image*. Again note that this is also performed on binary images. """ hull1 = convex_hull_image(horse) plot_comparison(horse, hull1, 'convex hull') """ .. image:: PLOT2RST.current_figure As the figure illustrates, ``convex_hull_image`` gives the smallest polygon which covers the white or True completely in the image. If we add a small grain to the image, we can see how the convex hull adapts to enclose that grain: """ import numpy as np horse2 = np.copy(horse) horse2[45:50, 75:80] = 1 hull2 = convex_hull_image(horse2) plot_comparison(horse2, hull2, 'convex hull') """ .. image:: PLOT2RST.current_figure Additional Resources ==================== 1. `MathWorks tutorial on morphological processing <http://www.mathworks.com/help/images/morphology-fundamentals-dilation-and-erosion.html>`_ 2. `Auckland university's tutorial on Morphological Image Processing <http://www.cs.auckland.ac.nz/courses/compsci773s1c/lectures/ImageProcessing-html/topic4.htm>`_ 3. http://en.wikipedia.org/wiki/Mathematical_morphology """ plt.show() "
