Provides scripts for testing the two algorithms as well as testing real time input.
% American Sign Language Detection
% Group 13
% This function performs SVM classification
function Ind = ASLsvm(cAlpha,nTrainingSamples,InImWeight,omega)
Training = omega';%Training based on features extracted
Ind = 1;
for ii = 2:size(cAlpha,2)
Group = [ii*ones(1,nTrainingSamples) Ind*ones(1,nTrainingSamples)];
%Perform classification between chosen and next group of trainng
Train = [Training((ii-1)*nTrainingSamples+1:(ii-1)*nTrainingSamples+nTrainingSamples,:); ...
SVMStruct = svmtrain(Train, Group);
Ind = svmclassify(SVMStruct, InImWeight);%Chosen group retained for next comparison
