h2. For students or mentors 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

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

*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
