Description

A simple module to calculate gradients of an image.

It should have one input and one output both named "image" which are of type MATRIX.

See opencv docs on how to implement it:
http://docs.opencv.org/doc/tutorials/imgproc/imgtrans/sobel_derivatives/sobel_derivatives.html

Check the GaussianModule for how to interact with data and parameters.

Each module needs a cpp for implementation and hpp for the header. To compile it, add it to the CMakeLists.txt.
Compile instrutctions are in the README.

If you need anything else, ask!

GradientModule.cpp

Enlightenment on dSigma used in GuassianBlur function and other regarding integration module in the code in YAML further. Will put forward questions in today's meeting

[cebe]

a draft implementation is available here: https://github.com/TU-Berlin-CVRS/uipf/blame/master/code/modules/improc/GradientModule.cpp needs a .hpp file and meta data + review of the implementation.

[akarsh]

Completed the gradient module.
