Robust Abnormal Event Recognition via Motion and Shape Analysis at ATM Installations

Algorithm 2

Feature generation from MHI using Hu moments.

Input: mhiImage

Output: hu

Moments = getMoments(mhiImage);

central_moments = getCentralMoment(moments);

norm_moments = getNormalizedCentralMoment(central_moments);

for   to 7 do

    hu[] = getHuMoments(norm_moments, );
