h2. How you will be evaluated if you are an accepted student

* Student projects to be paid only if:

** *Midterm:*

*** You must generate a pull request

**** That builds

**** Has at least stubbed out functionality

**** With appropriate Doxygen documentation

**** Has at least stubbed out unit test

**** Has a stubbed out example of use that builds

** *End of summer:*

*** A full pull request

**** Full Doxygen documentation

**** A good unit test

**** Example of use code

*** Create a (short!) Movie (preferably on Youtube, but any movie) that demonstrates your code

**** We use this to create an overall summary. Past years:

***** "The 2014 Movie":https://www.youtube.com/watch?v=7WUZA_KIIRA&feature=youtu.be

***** "The 2013 Movie":https://www.youtube.com/watch?v=_TTtN4frMEA

h2. For students interested in applying

# You *must* already know how to program well in C++

** Some projects may require Python or Matlab skills

# Discuss projects below or other ideas with us https://groups.google.com/forum/?fromgroups#!forum/opencv-gsoc-2015

# Go to the "GSoC site":http://www.google-melange.com/gsoc/homepage/google/gsoc2015 and sign up

# Post the project from below or your own agreed on project on the GSoC site to the Open Source Computer Vision organization

h2. For computer vision professionals interested in mentoring

# Go to the "GSoC site":http://www.google-melange.com/gsoc/homepage/google/gsoc2015 and sign up.

# Request to be a mentor for OpenCV there.

# We accept or reject you

# Students submit projects and you 

** find a project you want to mentor (several students might try for the same project)

** contact us about it through [email protected] so we can be sure there is not someone already handling that project

** contact the students to assess which one if any are capable of coding that up in a summer.

# We get a slot allocation from Google, the administrators then _"spend"_ the slots in order of priority

# Students must finally actually accept to do that project (some sign up for multiple organizations and then choose)

*If* you are accepted as a mentor *and* you find a suitable student *and* we give you a slot *and* the student signs up for it, +*then*+ you are a mentor. 

** It sounds harder than it is.

h1. 2015 Project Ideas:

*Students may propose their own projects (give us a clear summary and why you can do this project). However, below are some of our priorities for this year* Contact us and/or discuss ideas at https://groups.google.com/forum/?fromgroups#!forum/opencv-gsoc-2015

_These are not in order of priority_

*1 Google Cardboard*

* Do visual odometry, SLAM etc for Google Cardboard

*2 Projection mapping (Projected Augmented Reality)*

* Calibrate a camera to a projector

* Put out structured light to learn the 3D map of what's in front of the camera

* Project the camera image, suitably rotated and shifted onto the scene

* Unity or some other program to start transforming the scene for projection mapping

** See http://www.creativebloq.com/video/projection-mapping-912849 to get ideas of what you can do with this

*3 Update OpenCV file storage so that it's readable by Python in OpenCV (move to YAML 1.2 Edition 3)*

* Mentor Prasanna

* OpenCV C++ writes out its own YAML tags which makes it incompatible with it's own Python and with external python readers

* Speedup fs reading/writing, add JSON support, add base64 (+RLE) support for large amounts of numerical data

* References

** YAML http://www.yaml.org

** Problem statement: http://stackoverflow.com/questions/11141336/filestorage-for-opencv-python-api

*4 Stereo correspondence improvements*

* More accurate and faster stereo correspondence (StereoBM/StereoSGBM) by using LBP/BRIEF/DAISY etc. per-pixel descriptors instead of sum-of-absolute-differences.

*5 Self-contained video codec(s)*

* There is draft version of self-contained motion jpeg encoder to be integrated to OpenCV.

* We will also need decoder, 12-bit jpeg support, multi-threaded encoder and decoder.

* There are some other codecs, like libvpx, which we can support and link right into highgui, without dependency from ffmpeg/libav.

*6 Deep learning*

* It would be cool if OpenCV could load and run deep networks trained with popular DNN packages like Caffe, Theano or Torch.

* GPU/OpenCL optimization and/or other optimizations (that can partly be contributed back to the upstream projects) are also encouraged.

*7 Better interactive camera calibration*

* Modern algorithms would allow us to recompute camera parameters after almost each frame, compute reprojection error, compute confidence intervals for the parameters.

* the partially occluded calibration patterns could be handled somehow to, especially if we want to estimate intrinsic parameters only.

* the application may show us the areas where the corner borders have been shown so that user can see how good are the data

*8 Create a much better calibration target, we will call it "Charuco*

* We know how to combine Aruco targets with checker boards to create a "super calibration" object

* It also can express ~1 billion distinct codes

* Implement  this for OpenCV

** "Aruco target finding description":http://www.uco.es/investiga/grupos/ava/node/26

** Great overview

*** "Automatic generation and detection of highly reliable fiducial markers under occlusion":http://www.uco.es/investiga/grupos/ava/sites/default/files/GarridoJurado2014.pdf

** A similar system to Arcuo: "AprilTag: A robust an dflexible visual fiducial system":http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=5979561&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D5979561

*9 Color Calibration and white balance* 

* With McBeth chart and with gray world algorithm (improve exisiting color constancy algorithms)

* Possibly collect deep learning way of doing this (needs large training set)

*10 Realtime image preprocessing algorithms (real time on mobile)*

* We and many other OpenCV users would definitely enjoy very fast denoising, color improvements, white balance etc. algorithms.

*11 Tracking improvements*

* TLD algorithm is implemented in OpenCV, but it needs improvements and optimizations.

* ASM/AAM can also be implemented, as well as the particle filter.

*12 PBM (part-based models) improvements*

* There is latentsvm package in opencv_contrib that needs to be improved (quality-wise and speed-wise).

* Adding training, even if it involves execution of external svmperf or other tool, is definitely appreciated too.

*13 Improving ICF/ACF + <some>Boost training and detection*

* In opencv_contrib there is initial version of the training application and detector based on integral channel features and boosting. Further improvements of this part would be really useful.

*14 numl+OpenCV, lua+OpenCV*

* there is emerging numl language, suitable for implementation of complex computationally-intensive algorithms. OpenCV bindings for this language would be really useful.

* the other language that is now used more often for ML and CV (thanks to Torch) is Lua; there are old bindings for a tiny part of OpenCV; could be useful to extend our autogenerated bindings to Lua.

*15 human interaction*

* gesture recognition

* human skeleton based on 2d or 3d 

*16 SfM*

* update libmv to OpenMVG and get the 3d viz from OpenCV

* Make the Structure from Motion Module coherent

*17 Quad Rotor Contrib*

* Apply much of the above into a quad rotor drone automatic tracking, mapping navigation etc module
