The research measured the plantar pressure of forty high-school students at the conditions of wearing jogging shoes and barefoot at speeds of 1.

Based on a through analysis of planar barefoot impressions,a footprint recognition model based on Bayesian decision was established.

An automatic quantitative analysis on the shape of barefoot impressions is performed by setting up an aligned coordinate system for each footprint and locating uniform landmarks for it,and precise shape measurements are provided for barefoot impressions using computational geometry method.

Morphology comparison of barefoot trace is quite useful in investigation.

To meet the needs of identification through stereo bare footprint,this paper proposed a method for comparability determination of 3D surface based on LIM(Lorentz Information Measure).

The plane bare footprints are the tracks information formed by the sole of foot through the force transmission acting on some rigid carrier in the case of body’s standing or walking.
