# Delphi-OpenCV
* OpenCV version - 2.4.13
* Development environment - Delphi 2010-10.3, FPC 3.0.4 Contributors:
Laentir Valetov (email: laex@bk.ru)
Mikhail Grigorev (email: sleuthhound@gmail.com)
## Requirements:
* Visual C++ Redistributable for Visual Studio 2015
Files: msvcp140.dll, msvcp140d.dll in "Delphi-OpenCV\redist\" or [here, but it is not exactly][2]
or from the repository (Delphi-OpenCV\redist\VC14):
```
(1) 32-bit in the "\x86"
(2) 64-bit in the "\x64"
```
* Shared library FFMPEG 4.2.1 for Windows can be downloaded from [here][5]
or from the repository (Delphi-OpenCV\redist\ffmpeg):
```
(3) FFmpeg 32-bit Shared "\x86"
(4) FFmpeg 64-bit Shared "\x64"
```
* Dynamic library OpenCV need to download [here][4]
Files: *2413.dll and *2413d.dll
After installing OpenCV:
```
(5) 32-bit in the C:\OpenCV\build\x86\vc14\bin\*.dll
(6) 64-bit in the C:\OpenCV\build\x64\vc14\bin\*.dll
```
* Some examples (FFMPEG) required [SDL 2.0 and SDL 1.2][3]
or from the repository (Delphi-OpenCV\redist\SDL\1.2 and \2.0):
```
(7) 32-bit - SDL.dll and SDL2.dll "\x86"
(8) 64-bit - SDL.dll and SDL2.dll "\x64"
```
# How to install:
## 1. Delphi environment setting
Download and unzip the [archive][1] or clone repository
```
git clone https://github.com/Laex/Delphi-OpenCV.git
```
Get the following directory structure
```
- Directory, for example, "C:\Delphi\OpenCV\"
- here are the executable files of the examples
- program for checking the environment
- empty directory for "Delphi-FFMPEG"
- packages for D10-D10.3
- redistributable packages
- media for working examples and Haar-cascades
- examples
- object pascal sources for OpenCV, SDL, OpenGL
- attempt for opencv 3
- blank for OpenCV 4
```
Run InitDelphiFFMPEG.cmd to initialize the Delphi-FFMPEG submodule. The directory should be populated with sources for Delphi-FFMPEG.
If it didn’t work, then
```
git clone https://github.com/Laex/Delphi-FFMPEG.git
```
Add the search path for the modules of the project in Delphi IDE
"Tools-Options-Delphi Options-Library-Library path" or "Tools-Options-Language-Delphi-Library"
```
\source
\source\opengl
\source\sdl
\source\sdl2
\packages
\resource
\resource\facedetectxml
\source3
\Delphi-FFMPEG\source
```
where `````` directory, which was unzipped (or cloned) repository.
## 2. Copy dynamic libraries files
OS Windows 64-bit
```
Target platform 64-bit: (2),(4),(6),(8) -> "C:\Windows\System32\"
Target platform 32-bit: (1),(3),(5),(7) -> "C:\Windows\SysWOW64\"
```
OS Windows 32-bit
```
Target platform 32-bit: (1),(3),(5),(7) -> "C:\Windows\System32\"
```
Alternatively, dynamic libraries can be placed next to an executable file.
## 3. Verify that the environment is configured correctly
Run from the repository
```
Delphi-OpenCV/CheckCVDep/CheckCVDep.exe
```
The program checks the availability of dynamic libraries
```
------- Verifying Microsoft DLL -------
OK
------- OpenCV DLL -------
OK
------- Delphi-OpenCV classes DLL -------
OK
------- FFMPEG DLL -------
OK
------- SDL DLL -------
OK
```
To successfully install components and run most of the examples, the availability of FFMPEG DLL, Microsoft DLL and OpenCV DLL is sufficient
## 4. Install the components
To install the components, open and install
```
\packages\Delphi XXX\rtpFFMPEG.dpk
\packages\Delphi XXX\rclVCLOpenCV.dpk
\packages\Delphi XXX\rclFMXOpenCV.dpk
\packages\Delphi XXX\dclVCLOpenCV.dpk
\packages\Delphi XXX\dclFMXOpenCV.dpk
```
## Examples
Open in Delphi IDE and compile:
Examples of the use of certain functions and procedures
```
\samples\LibDemo\LibDemo.groupproj
```
Examples of the use of video processing algorithms
```
\samples\MultiDemo\MultiDemo.groupproj
```
Examples of the use of video processing algorithms using VCL.Forms
```
\samples\VCLDemo\VCLDemo.groupproj
```
Examples of using FFMPEG library header files are in the
```
\Delphi-FFMPEG\examples
```
Examples of use of components
```
\samples\Components\ComponentsDemo.groupproj
```
