Repository for OpenCV's extra modules
This repository is intended for the development of so-called "extra" modules,
contributed functionality. New modules quite often do not have stable API,
and they are not well-tested. Thus, they shouldn't be released as a part of the
official OpenCV distribution, since the library maintains binary compatibility,
and tries to provide decent performance and stability.
So, all the new modules should be developed separately, and published in theopencv_contrib repository at first. Later, when the module matures and gains
popularity, it is moved to the central OpenCV repository, and the development team
provides production-quality support for this module.
How to build OpenCV with extra modules
You can build OpenCV, so it will include the modules from this repository. Contrib modules are under constant development and it is recommended to use them alongside the master branch or latest releases of OpenCV.
Here is the CMake command for you:
text
$ cd <opencv_build_directory>
$ cmake -DOPENCV_EXTRA_MODULES_PATH=<opencv_contrib>/modules <opencv_source_directory>
$ make -j5As the result, OpenCV will be built in the <opencv_build_directory> with all
modules from opencv_contrib repository. If you don't want all of the modules,
use CMake's BUILD_opencv_* options. Like in this example:
text
$ cmake -DOPENCV_EXTRA_MODULES_PATH=<opencv_contrib>/modules -DBUILD_opencv_legacy=OFF <opencv_source_directory>If you also want to build the samples from the "samples" folder of each module, also include the "-DBUILD_EXAMPLES=ON" option.
If you prefer using the GUI version of CMake (cmake-gui), then, you can add opencv_contrib modules within opencv core by doing the following:
Start cmake-gui.
Select the opencv source code folder and the folder where binaries will be built (the 2 upper forms of the interface).
Press the
configurebutton. You will see all the opencv build parameters in the central interface.Browse the parameters and look for the form called
OPENCV_EXTRA_MODULES_PATH(use the search form to focus rapidly on it).Complete this
OPENCV_EXTRA_MODULES_PATHby the proper pathname to the<opencv_contrib>/modulesvalue using its browse button.Press the
configurebutton followed by thegeneratebutton (the first time, you will be asked which makefile style to use).Build the
opencvcore with the method you chose (make and make install if you chose Unix makefile at step 6).To run, linker flags to contrib modules will need to be added to use them in your code/IDE. For example to use the aruco module, "-lopencv_aruco" flag will be added.
Update the repository documentation
In order to keep a clean overview containing all contributed modules, the following files need to be created/adapted:
Update the README.md file under the modules folder. Here, you add your model with a single-line description.
Add a README.md inside your own module folder. This README explains which functionality (separate functions) is available, links to the corresponding samples, and explains in somewhat more detail what the module is expected to do. If any extra requirements are needed to build the module without problems, add them here also.

High-level design overview {#gapi_hld}
[TOC]
G-API High-level design overview
G-API is a heterogeneous framework and provides an unified API to
program image processing pipelines with a number of supported
backends.
The key design idea is to keep pipeline code itself platform-neutral
while specifying which kernels to use and which devices to utilize
using extra parameters at graph compile (configuration) time. This
requirement has led to the following architecture:
There are three layers in this architecture:
- API Layer -- this is the top layer, which implements G-API
public interface, its building blocks and semantics.
When user constructs a pipeline with G-API, he interacts with this
layer directly, and the entities the user operates on (like cv::GMat
or cv::GComputation) are provided by this layer. - Graph Compiler Layer -- this is the intermediate layer which
unrolls user computation into a graph and then applies a number of
transformations to it (e.g. optimizations). This layer is built atop
of [ADE Framework](@ref gapi_detail_ade). - Backends Layer -- this is the lowest level layer, which lists a
number of Backends. In contrast with the above two layers,
backends are highly coupled with low-level platform details, with
every backend standing for every platform. A backend operates on a
processed graph (coming from the graph compiler) and executes this
graph optimally for a specific platform or device.
API layer {#gapi_api_layer}
API layer is what user interacts with when defining and using a
pipeline (a Computation in G-API terms). API layer defines a set of
G-API dynamic objects which can be used as inputs, outputs, and
intermediate data objects within a graph:
- cv::GMat
- cv::GScalar
- cv::GArray (template class)
API layer specifies a list of Operations which are defined on these
data objects -- so called kernels. See G-API [core](@ref gapi_core)
and [imgproc](@ref gapi_imgproc) namespaces for details on which
operations G-API provides by default.
G-API is not limited to these operations only -- users can define
their own kernels easily using a special macro G_TYPED_KERNEL().
API layer is also responsible for marshalling and storing operation
parameters on pipeline creation. In addition to the aforementioned
G-API dynamic objects, operations may also accept arbitrary
parameters (more on this [here](@ref gapi_detail_params)), so API
layer captures its values and stores internally upon the moment of
execution.
Finally, cv::GComputation and cv::GCompiled are the remaining
important components of API layer. The former wraps a series of G-API
expressions into an object (graph), and the latter is a product of
graph compilation (see [this chapter](@ref gapi_detail_compiler) for
details).
Graph compiler layer {#gapi_compiler}
Every G-API computation is compiled before it executes. Compilation
process is triggered in two ways:
- implicitly, when cv::GComputation::apply() is used. In this case,
graph compilation is then immediately followed by execution. - explicitly, when cv::GComputation::compile() is used. In this case,
a cv::GCompiled object is returned which then can be invoked as a
C++ functor.
The first way is recommended for cases when input data format is not
known in advance -- e.g. when it comes from an arbitrary input file.
The second way is recommended for deployment (production) scenarios
where input data characteristics are usually predefined.
Graph compilation process is built atop of ADE Framework. Initially, a
bipartite graph is generated from expressions captured by API layer.
This graph contains nodes of two types: Data and Operations. Graph
always starts and ends with a Data node(s), with Operations nodes
in-between. Every Operation node has inputs and outputs, both are Data
nodes.
After the initial graph is generated, it is actually processed by a
number of graph transformations, called passes. ADE Framework acts
as a compiler pass management engine, and passes are written
specifically for G-API.
There are different passes which check graph validity, refine details
on operations and data, organize nodes into clusters ("Islands") based
on affinity or user-specified regioning[TBD], and more. Backends also
are able to inject backend-specific passes into the compilation
process, see more on this in the [dedicated chapter](@ref gapi_detail_meta).
Result of graph compilation is a compiled object, represented by class
cv::GCompiled. A new cv::GCompiled object is always created regardless
if there was an explicit or implicit compilation request (see
above). Actual graph execution happens within cv::GCompiled and is
determined by backends which participated in the graph compilation.
@sa cv::GComputation::apply(), cv::GComputation::compile(), cv::GCompiled
Backends layer {#gapi_backends}
The above diagram lists two backends, OpenCV and Fluid. OpenCV
is so-called "reference backend", which implements G-API operations
using plain old OpenCV functions. This backend is useful for
prototyping on a familiar development system. Fluid is a plugin for
cache-efficient execution on CPU -- it implements a different
execution policy and operates with its own, special kernels. Fluid
backend allows to achieve less memory footprint and better memory
locality when running on CPU.
There may be more backends available, e.g. Halide, OpenCL, etc. --
G-API provides an uniform internal API to develop backends so any
enthusiast or a company are free to scale G-API on a new platform or
accelerator. In terms of OpenCV infrastructure, every new backend is a
new distinct OpenCV module, which extends G-API when build as a part
of OpenCV.
Graph execution {#gapi_compiled}
The way graph executed is defined by backends selected for
compilation. In fact, every backend builds its own execution script as
the final stage of graph compilation process, when an executable
(compiled) object is being generated. For example, in OpenCV backend,
this script is just a topologically-sorted sequence of OpenCV
functions to call; for Fluid backend, it is a similar thing -- a
topologically sorted list of Agents processing lines of input on
every iteration.
Graph execution is triggered in two ways:
- via cv::GComputation::apply(), with graph compiled in-place exactly
for the given input data; - via cv::GCompiled::operator()(), when the graph has been precompiled.
Both methods are polimorphic and take a variadic number of arguments,
with validity checks performed in runtime. If a number, shapes, and
formats of passed data objects differ from expected, a runtime
exception is thrown. G-API also provides typed wrappers to move
these checks to the compile time -- see cv::GComputationT<>.
G-API graph execution is declared stateless -- it means that a
compiled functor (cv::GCompiled) acts like a pure C++ function and
provides the same result for the same set of input arguments.
Both execution methods take \f$N+M\f$ parameters, where \f$N\f$ is a
number of inputs, and \f$M\f$ is a number of outputs on which a
cv::GComputation is defined. Note that while G-API types (cv::GMat,
etc) are used in definition, the execution methods accept OpenCV's
traditional data types (like cv::Mat) which hold actual data -- see
table in [parameter marshalling](@ref gapi_detail_params).
