ECVL - European Computer Vision Library

Documentation

The ECVL documentation is available here.

Requirements

• CMake 3.13 or later
• C++ Compiler with C++17 support (e.g. GCC 7 or later, Clang 5.0 or later, Visual Studio 2017 or later)
• OpenCV 3.0 or later (modules required: core, imgproc, imgcodecs, photo, [calib3d since OpenCV 4.0 only. Note that calib3d depends on features2d and flann])

Optional

• EDDL, European Distributed Deep Learning Library (ECVL_BUILD_EDDL flag)

• wxWidgets, required if ECVL_BUILD_GUI flag is enabled (wxWidgets build steps available here)

  • OpenGL 3.3 or later, required by the 3D viewer enabled by ECVL_BUILD_GUI flag

• OpenSlide, required with ECVL_WITH_OPENSLIDE flag

Installation

Clone and install ECVL with:

git clone https://github.com/deephealthproject/ecvl.git
mkdir build && cd build
cmake ..
cmake --build . --config Release --parallel 4
cmake --build . --config Release --target install

CMake flags and options:

• -DECVL_TESTS (default ON): Compiles tests
• -DECVL_BUILD_EDDL (default ON): Compiles EDDL integration module (it automatically enables ECVL_DATASET option)
• -DECVL_BUILD_DEPS (default ON): Whether to build 3rdparty dependencies or looks for them on the system
• -DECVL_BUILD_EXAMPLES (default OFF): Compiles examples and downloads examples data
• -DECVL_BUILD_GUI (default OFF): Compiles GUI module
• -DECVL_DATASET (default OFF): Compiles dataset module
• -DECVL_WITH_OPENGL (default OFF): Enables 3D GUI functionalities
• -DECVL_WITH_DICOM (default OFF): Enables DICOM format support
• -DECVL_WITH_OPENSLIDE (default OFF): Enables OpenSlide whole-slide image support

ECVL installation example

ECVL installation with all options enabled and required libraries installed in "non-standard" system directories:

git clone https://github.com/deephealthproject/ecvl.git
mkdir build && cd build
cmake \
  -DECVL_BUILD_EXAMPLES=ON \
  -DECVL_BUILD_EDDL=ON \
  -DECVL_DATASET=ON \
  -DECVL_BUILD_GUI=ON \
  -DECVL_WITH_OPENGL=ON \
  -DECVL_WITH_DICOM=ON \
  -DECVL_WITH_OPENSLIDE=ON \
  -DCMAKE_INSTALL_PREFIX=install \
  -DOpenCV_DIR=/home/<user>/opencv/build \
  -Deddl_DIR=/home/<user>/eddl/build/install/lib/cmake/eddl \
  -DOPENSLIDE_INCLUDE_DIRECTORIES=/home/<user>/openslide_src/include/openslide \
  -DOPENSLIDE_LIBRARIES=/home/<user>/openslide_src/lib/libopenslide.so \
  -DwxWidgets_CONFIG_EXECUTABLE=/home/<user>/wxWidgets/build/install/bin/wx-config ..
cmake --build . --config Release --parallel 4
cmake --build . --config Release --target install

ImageWatch plugin for Microsoft Visual Studio

An extension of ImageWatch is available to visually inspect ecvl::Image when debugging. In order to use it be sure to install the ImageWatch plugin for Visual Studio and copy and past the file tools/ECVL.natvis from the GitHub repo into C:\Users\<!!username!!>\Documents\Visual Studio 2017\Visualizers
