OverviewIntroductionDesign Decisions and System ChangesImplementationTools UsedProject PlanDemo

IntroductionInteractive Conducting SystemTracks hands using webcamReal-time alterations depending on hand gestures

Change volumeChange tempo

Design Decisions and System changesUse Haar classifiers to detect the faceDynamically check for skin colourTrack left hand only when needed

ImplementationDetect face and block it out

ImplementationConvert frame into HSV colour space

Implementationset hand as region of interest

ImplementationHSV image split up into separate components

ImplementationCreate histogram of skin colour

ImplementationTrack the right hand (CAMshift)

ImplementationPlay music

ImplementationChoose ensemble or entire orchestra

ImplementationTrack left hand

Tools UsedUbuntu 12.04Qt Creator with Qt 4.7OpenCV 2.4Rtcmix 4.0.1

DemoDemo Overview

Track right handChange the tempo of musicTrack left handDecrease volume of symphonyIncrease volume of one ensemble
