Recap
A system which allows users to convert 2D videos into an Anaglyph 3D equivalent.
Converted video can then be viewed on any normal TV or monitor, with 3D anaglyph glasses.

Low Level Design
Low Level Design
• Video needs to be broken up into frames
• cvQueryFrame( capture )
Low Level Design
• Convert BGR colour space to RGB colour space
• cvtColor(left, left, CV_BGR2RGB);
Low Level Design
• Dubois
– Least square approximation to produce a
matrix
– MatrixMultiply(Limage[3][1],Rimage[3][1])
Low Level Design
• Depth Map
– Using depth map we displace original image by some amount
– Displace(Image,DepthMap)
– D=30.0*((I-127.5)/(127.5));
– Where D is the amount to displace and I is the current pixel of
the depth map
Low Level Design
• Output
– Display video frames
– cvShowImage( “example", frame );
