Analysis of human motion using snakes and neural networks

A novel technique is described for analysing human movement in outdoor scenes. Following initial detection of the humans using active contour models, the contours are then re-represented as normalised axis crossover vectors. These vectors are then fed into a neural network which determines the typicality of a given human shape, allowing for a given human’s motion deformation to be analysed. Experiments are described which investigate the success of the technique being presented.
