Detailed Description

This version drop support for legacy OpenCV version 1 (C style) API over the OpenCV version 2 (C++ style) API. Despite the change was more than 7 years ago, some application keep using the C style API as compatibility was kept up to OpenCV 3.x.

The main advantage of OpenCV 4 is a modern Computer Vision Framework advertising

Few packages will need to be ported to work with OpenCV 4.2.x

Scope

  • Proposal owners:

Update OpenCV to version 4.2.x and rebuilt few applications that depends on it.

  • Other developers: N/A (not a System Wide Change)
  • Policies and guidelines: N/A (not a System Wide Change)
  • Trademark approval: N/A (not needed for this Change)

Contingency Plan

If few applications are missing support for OpenCV 4.x they will be built with OpenCV support disabled if such support is optional. Application where upstream is already in-active are unlikely to be worked on in the scope of this proposal.
