3D to 2D conversion for images

[raj.kumar]

I need to convert 3D images to 2D images for multiple formats: jpg, mp4, mpo etc from my PHP application.
(Basically, I need to crop one of the two images in the stereoscopic 3D file.)

Could anyone suggest any frameworks/libraries which can help me with this.

What do you mean by 3D? Do you mean a pair of stereographic images? Is all you want to do simply to crop one of the two stereo images and not the other? If so, IM can do a crop of an image and output it to many formats.

convert image -crop WxH+X+Y +repage output

What platform are you on? Do you have IM installed? If so, what version? Do you want to use the command line as above or one of the APIs

see

You can use simple PHP with the exec command to run an IM command line or you can rewrite the command line in one of the PHP API formats, e.g.

MagickWand for PHP
or
IMagick

Thanks for your reply. This is useful. I do have IM installed in a Linux environment.
So this will take care of converting 3D stereoscopic images to 2D.

Any idea how can I do this for 3D video to 2D video conversion ?
I think, IM works only for images. But how about any pointers to the commands
in tools like ffmpeg, flix, or others?

Thanks again,
Raj

I am still puzzled by your 3D format? What type of image is it? Is it just two images each such as tiff or png or jpg? What is it you are really trying to do?



You can install the ffmpeg delegate library and any others you want and then reinstall IM from source and then IM will use ffmpeg to deal with videos.

type

convert -list configure

and see what delegates IM knows about. If ffmpeg is installed it will include mpeg. Look at the line starting with DELEGATES. For example I have

DELEGATES bzlib fftw fontconfig freetype gs jpeg jng jp2 lcms2 lqr lzma mpeg openexr png rsvg tiff x11 xml zlib


You can also see what format IM can use with your configuration by typing:

convert -list format
