OpenCV/Minutes 2008-07-21¶

Agenda¶

Current Goals in Priority Order

1. 3D Vision
   1. Stereo Rectification (Vadim)
   2. Stereo Correspondence
      1. Fast Version using correlation windows (Vadim)
      2. Kolmogorov Graph Cut Energy Minimization Method (Victor and Sergey)
   3. Regression tests for chessboard finder, calibration, stereo calibration and rectification
2. Feature Toolbox (Alex)
3. Improve Python interface (Vadim)
4. Google OpenCV Wrappers (Vadim, Daniel Filip)

Minutes¶

Vadim

• Google OpenCV Wrappers (done)
• Jean-Yves style rectification (this week)
• Correlation stereo correspondence (next week)

Victor and Sergey

• Kolmogorov first pass and first optimization (done)
• Reorganize code for OpenCV compatibility and add in correspondence constraints (2 weeks)

Alex

• Has 3 versions of SIFT and 1 SURF, writing a keypoint stability analysis/regression test tool (this week)

Gary

• Get kids party rectified stereo data to Alex (this week)
• Get feature citations to Alex (this week)
• Get Jack's MSER and Code to Alex ( this week)

Kurt

• Get stereo correspondence code to Vadim (this week)

Action Items ¶

• Get whole stereo toolchain going with regression tests
• DoG, MSER, Harris, SURF, Star Keypoint detectors
• SIFT, SURF, DAISY, Lepetit, PHOG, PHOW features

OpenCV/Minutes 2008-07-28¶

Agenda¶

Update of calibration and stereo, start of feature toolbox

Minutes¶

Vadim

• Checked in Stereo calibration and rectification code to OpenCV! Sent me calibration code example.

Victor/Sergey

• Timing analysis of Kolmogorov's method.

Alex

• Analysed SIFT vs SURF on dataset
• Sent proposed keypoint detector/descriptor function

Kurt

• Sent correspondence code example.

Action Items ¶

• Vadim to
  • fix any issues that come up in stereo calibration and rectification code,
  • look over book doc of these functions and
  • start working on stereo correspondence.

• Victor/Sergey:
  • Literature and code search of energy minimization.
  • Decide on reimplement graph minimization or BP or to drop

• Gary:
  • Get Alex data examples of party plates, left and right views.
  • Start desired features list.
  • WG detector code to Russia.
  • Discuss changing contract with WG and Argus to focus on features and recognition along with fast stereo.
  • Set out better long term plans.

• Kurt:
  • Look at stereo calibration and rectification results.

• Alex:
  • Surf and SIFT into OpenCV as start of key detectors and key descriptors toolbox
  • Run on WG detector.
  • Convert PHOG/PHOW for use on Opencv
