[mrpt-img]

Detailed Description

Basic computer vision data structures and tools: bitmap images, canvas, color maps, and pinhole camera models.

Library `mrpt-img`

[New in MRPT 2.0.0]

This C++ library is part of MRPT and can be installed in Debian-based systems with:

    sudo apt install libmrpt-img-dev

See: Using MRPT from your CMake project

Find below some examples of use.

Image handling

The class mrpt::img::CImage represents a wrapper around OpenCV images, plus extra functionality such as on-the-fly loading of images stored in disk upon first usage. The cv::Mat object is always available so OpenCV's functions can be still used to operate on MRPT images.
