PostgreSQL Session API
======================
The Session classes wrap the Queries :py:class:`Session <queries.Session>` and
:py:class:`TornadoSession <queries.tornado_session.TornadoSession>` classes
providing environment variable based configuration.
Environment variables should be set using the ``PGSQL[_DBNAME]`` format
where the value is a PostgreSQL URI.
For PostgreSQL URI format, see:
http://www.postgresql.org/docs/9.3/static/libpq-connect.html#LIBPQ-CONNSTRING
As example, given the environment variable:
.. code:: python
PGSQL_FOO = 'postgresql://bar:baz@foohost:6000/foo'
and code for creating a :py:class:`Session` instance for the database name
``foo``:
.. code:: python
session = sprockets.postgresql.Session('foo')
A :py:class:`queries.Session` object will be created that connects to Postgres
running on ``foohost``, port ``6000`` using the username ``bar`` and the
password ``baz``, connecting to the ``foo`` database.

"""Calculate the grey-level co-occurrence matrix.
A grey level co-occurence matrix is a histogram of co-occuring
greyscale values at a given offset over an image.
Parameters
----------
image : array_like of uint8
Integer typed input image. The image will be cast to uint8, so
the maximum value must be less than 256.
distances : array_like
List of pixel pair distance offsets.
angles : array_like
List of pixel pair angles in radians.
levels : int, optional
The input image should contain integers in [0, levels-1],
where levels indicate the number of grey-levels counted
(typically 256 for an 8-bit image). The maximum value is
256.
symmetric : bool, optional
If True, the output matrix `P[:, :, d, theta]` is symmetric. This
is accomplished by ignoring the order of value pairs, so both
(i, j) and (j, i) are accumulated when (i, j) is encountered
for a given offset. The default is False.
normed : bool, optional
If True, normalize each matrix `P[:, :, d, theta]` by dividing
by the total number of accumulated co-occurrences for the given
offset. The elements of the resulting matrix sum to 1. The
default is False.
Returns
-------
P : 4-D ndarray
The grey-level co-occurrence histogram. The value
`P[i,j,d,theta]` is the number of times that grey-level `j`
occurs at a distance `d` and at an angle `theta` from
grey-level `i`. If `normed` is `False`, the output is of
type uint32, otherwise it is float64.

Method to determine the pattern.
* 'default': original local binary pattern which is gray scale but not
rotation invariant.
* 'ror': extension of default implementation which is gray scale and
rotation invariant.
* 'uniform': improved rotation invariance with uniform patterns and
finer quantization of the angular space which is gray scale and
rotation invariant.
* 'nri_uniform': non rotation-invariant uniform patterns variant
which is only gray scale invariant [2].
* 'var': rotation invariant variance measures of the contrast of local
image texture which is rotation but not gray scale invariant.
Returns
-------
output : (N, M) array
LBP image.

config.
Either you can fill the config from a config file::
app.config.from_pyfile('yourconfig.cfg')
Or alternatively you can define the configuration options in the
module that calls :meth:`from_object` or provide an import path to
a module that should be loaded. It is also possible to tell it to
use the same module and with that provide the configuration values
just before the call::
DEBUG = True
SECRET_KEY = 'development key'
app.config.from_object(__name__)
In both cases (loading from any Python file or loading from modules),
only uppercase keys are added to the config. This makes it possible to use
lowercase values in the config file for temporary values that are not added
to the config or to define the config keys in the same file that implements
the application.
Probably the most interesting way to load configurations is from an
environment variable pointing to a file::
app.config.from_envvar('YOURAPPLICATION_SETTINGS')
In this case before launching the application you have to set this
environment variable to the file you want to use. On Linux and OS X
use the export statement::
export YOURAPPLICATION_SETTINGS='/path/to/config/file'
On windows use `set` instead.

Objects are usually either modules or classes. :meth:`from_object`
loads only the uppercase attributes of the module/class. A ``dict``
object will not work with :meth:`from_object` because the keys of a
``dict`` are not attributes of the ``dict`` class.
Example of module-based configuration::

rather configuration defaults. The actual config should be loaded

"""
Display current network and ip address for newer Huwei modems.
It is tested for Huawei E3276 (usb-id 12d1:1506) aka Telekom Speed
Stick LTE III but may work on other devices, too.
DEPENDENCIES:
- netifaces
- pyserial
Configuration parameters:
- baudrate : There should be no need to configure this, but
feel free to experiment.
Default is 115200.
- cache_timeout : How often we refresh this module in seconds.
Default is 5.
- consider_3G_degraded : If set to True, only 4G-networks will be
considered 'good'; 3G connections are shown
as 'degraded', which is yellow by default. Mostly
useful if you want to keep track of where there
is a 4G connection.
Default is False.
- format_down : What to display when the modem is not plugged in
Default is: 'WWAN: down'
- format_error : What to display when modem can't be accessed.
Default is 'WWAN: {error}'
- format_no_service : What to display when the modem does not have a
network connection. This allows to omit the then
meaningless network generation. Therefore the
default is 'WWAN: ({status}) {ip}'
- format_up : What to display upon regular connection
Default is 'WWAN: ({status}/{netgen}) {ip}'
- interface : The default interface to obtain the IP address
from. For wvdial this is most likely ppp0.
For netctl it can be different.
Default is: ppp0
- modem : The device to send commands to. Default is
- modem_timeout : The timespan betwenn querying the modem and
collecting the response.
Default is 0.4 (which should be sufficient)
