Parallelism

Video processing using Intel TBB (Threading Building Block).

The project:

---

This is a school project whose objective is perform some treatments on videos, such as:

• Blur a video
• Swap content of a video with another
• Edge detection
• And more...

However, such treatments can take a very long time to perform, especially if the video is big.

This is why we want to use the power of multithreading.

TBB:

---

TBB (Threading Building Block) is a library developped by Intel that allows to take advantage of the power of multi-core processor performance without being an expert in multithreading. It offers you a simple, clean, C++ oriented way to greatly improve the performances of your programs.

How to use:

---

First you need a compiler that supports C++11 (g++ 4.6 at least, or clang 3.1).

To compile the project:

• cmake .
• make

To use it:

./prpa video1 [video2] options outputVideo

• video1 is a mandatory argument, it must a .avi formated video
• If your process requires a second video (for instance you want to swap content), then video2 is this extra video
• outputVideo is the name of the video that will be created by the program

For the options, if your process only requires 1 video:

• --blur
• --sharpen
• --edge
• --light
• --dark

Else, if you have a second video

• -swap : will swap content between the first and the second video
• -blend : will blend the 2 videos

Of course, you can have several options queued.
