Overview RECAP USER INTERFACE SPECIFICATION HIGH LEVEL DESIGN LOW LEVEL DESIGN DEMO REFERENCES QUESTIONS & ANSWERS

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.

User Interface Specification

Graphic User Interface (GUI) Users will interact by selecting options from menu’s

User Interface Specification Display Window

User Interface Specification Opening a file

User Interface Specification Converting the file

User Interface Specification Play back of 3D output

User Interface Specification Saving the 3D output

High level design Output

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 );
