Java Anaglyph & Polarization 3d Library 🕶️ for Images and Movies

movie-fleur 🌻

Convert 3D movies with splited Frames to Anaglyph 3D movies to watch with 3d Red (Blue/Cyan/Green) Glasses

Convert from video file with given framePosition

If a 3D video is available the frames can be extracted from the Video by applying the frame Position. 3D video Files can be found here: YTS

BufferedImage frame = FleurVideo.extract(new File("3dVideo.mp4"), 6000);

List<BufferedImage> splited = Fleur3dUtil.split(frame);
BufferedImage frameCombined = FleurFilter.additive(
        FleurFilter.color(splited.get(0), ColorMask.RED),
        FleurFilter.color(splited.get(1), ColorMask.CYAN));

ImageHelper.saveImage(frameCombined, "frame_combined.png");

1. Extract frames from video file

FleurVideo.extract(new File("3dVideo.mp4"), 6000);

2. Split and stretch frames

left	right

List<BufferedImage> splited = Fleur3dUtil.split(frame);

3. Combine Frames to one image (No color filtering)

BufferedImage combined = FleurFilter.alphaCombine(frame1, frame2);

4. Apply color filter

left	right
RGB(x, 0, 0) / 0xFFFF0000	RGB(0, x, x) / 0xFF00FFFF

BufferedImage redFilterImg = FleurFilter.color(splited.get(0), FilterColor.RED);
BufferedImage greenBlueFilterImg = FleurFilter.color(splited.get(1), FilterColor.CYAN);

5. Combined with filter

Additive Color filtering => For every Pixel on final Image RGB(LeftImage.red, RightImage.green, RightImage.blue)

BufferedImage additiveCombinedFrame = FleurFilter.additive(
        FleurFilter.color(splited.get(0), FilterColor.RED),
        FleurFilter.color(splited.get(1), FilterColor.CYAN)
);

6. Compile to Video

// Extract images from Video (specific from frames 6000 - 6200)
List<BufferedImage> images
        = FleurVideo.extract(new File("3dVideo.mp4"), 6000, 6010);

List<BufferedImage> videoImages = new ArrayList<>();
for (BufferedImage image : images) {
    List<BufferedImage> splits = Fleur3dUtil.split(image);

    videoImages.add(FleurFilter.additive(
            FleurFilter.color(splits.get(0), ColorMask.RED),
            FleurFilter.color(splits.get(1), ColorMask.CYAN)
    ));
}

FleurVideo.create(videoImages, "3dVideoOut.mp4");

7. Compile to polarized 3d Video (left/right)

List<BufferedImage> images = FleurVideo.extract(new File("3dVideo.mp4"), 6000, 6100);

List<BufferedImage> leftArray = new ArrayList<>();
List<BufferedImage> rightArray = new ArrayList<>();

for (BufferedImage image : images) {
    List<BufferedImage> splits = Fleur3dUtil.split(image);
    leftArray.add(splits.get(0));
    rightArray.add(splits.get(1));
}

FleurVideo.create(leftArray, "left.mp4");
FleurVideo.create(rightArray, "right.mp4");

To use: play both videos at the same frames but on two diffrent beamers.... I dont have two beamers... well. I havent tested this acctually

Or use active shutter 3d glasses requires 60hz monitor and switching on each frame to the other video... Active_shutter_3D_system
