## How to install:
Download the [archive][1].<br>
Unzip it to a convenient directory, thus get the following directory structure<br>
```
<PROJECT_ROOT> - Directory, for example, "C:\Delphi\OpenCV\"
	<bin>
	<redist>
	<resource>
	<samples>
	<source>
```
Add the search path for the modules of the project in Delphi IDE (Tools-Options-Delphi Options-Library-Library path)
```
<PROJECT_ROOT>\source
<PROJECT_ROOT>\source\classes
<PROJECT_ROOT>\source\component
<PROJECT_ROOT>\source\ffmpeg
<PROJECT_ROOT>\source\opengl
<PROJECT_ROOT>\source\sdl
<PROJECT_ROOT>\source\sdl2
<PROJECT_ROOT>\source\utils
<PROJECT_ROOT>\resource\facedetectxml
```
where ```<PROJECT_ROOT>``` directory, which was unzipped project.<br>

To install the components, open and install
```
<PROJECT_ROOT>\source\component\DelphiXX\dclCommonOpenCVXXX.dpk
<PROJECT_ROOT>\source\component\DelphiXX\dclFFMSourceXXX.dpk
<PROJECT_ROOT>\source\component\DelphiXX\dclFMXOpenCVXXX.dpk
<PROJECT_ROOT>\source\component\DelphiXX\dclVCLOpenCVXXX.dpk
```
