*** 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 2015 Movie":https://www.youtube.com/watch?v=OUbUFn71S4s

***** "The 2014 Movie":https://www.youtube.com/watch?v=3f76HCHJJRA

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

h2. For students interested in applying

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

** Some projects may require Python or Matlab skills

# Ask to join the "OpenCV GSoC Forum List":https://groups.google.com/forum/#!forum/opencv-gsoc-2016

** Discuss projects below or other ideas with us there (Feb 29 - March 13)

# On March 14th - 25th, Go to the "GSoC site":https://developers.google.com/open-source/gsoc/ and sign up to be a student with OpenCV

# Post the project from below or your own agreed on project on the GSoC to [email protected]

** Include Name, google email, age

** Include how you think you are qualified to accomplish this project (skills, courses, relevant background)

** Include Country of origin, school you are enrolled in, Professor you work with (if any)

** Include a projected timeline and milestones for the project

# Once (and if!) OpenCV gets accepted as GSoC 2016 org (Feb 29th), and we are told how many slots we will get *and* you've signed up for a project with us (March 14-25th)

** We will weight the students and projects against mentors and their interests and choose which students/project to pursue.

** Accepted students will be posted on the GSoC site on April 22nd (and we will notify the accepted students ourselves).

h2. For computer vision professionals interested in mentoring

# Go to the "GSoC site":https://developers.google.com/open-source/gsoc/ 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. 2016 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

*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 lua+OpenCV*

* 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 

*17 Quad Rotor Contrib*

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

New 2016 ideas:

*Architecture

* Exceptions in OpenCV need to be easily disabled ? (need to check if that's the case or not)

* Minimal OpenCV: give the functions you want, it gives you a minimal version of the library. 

* reduce the size of OpenCV on Anddroid

* create a more C++ type (to be able to deal with constness and separate the pointer from the type)

* create an image type (that would also have color information, maybe calibration too) and implement a proper resize algorithm for that type

*Tracking

* David Tan’s tracking

2d: https://www.youtube.com/watch?v=W689ffCMDF4

3d: https://www.youtube.com/watch?v=TqyFEZzhPbE

*misc

* convexHull is implemented with Sklansky's second, 1982 algorithm, which is incorrect in some case, and suboptimal complexity-wise. cf. http://cgm.cs.mcgill.ca/~athens/cs601/.

cv::contourArea(cv::convexHull(contour)) for a convex contour is different from cv::contourArea(contour), somtimes by nearly 30%.
