Abstract:
1. A method for detecting, classifying and tracking a pedestrian present in front of a vehicle by using images captured by a near infrared (IR) camera disposed on the vehicle, the method comprising processor implemented steps of: a) detecting a road to focus attention for filtering region of interest (ROI) objects in the image by estimating a ground region characterized by identifying smooth regions connected to a bottom most part of the image; b) eliminating non-ground objects based on their distance to the ground; c) filtering non-ROI objects based on a shape of the objects by computing a signal to noise ratio (SNR) which is a measure of regularity of a component based on its periodicity of its contour for each of such non-ROI objects; d) eliminating non-vertical objects by computing inertial moment relative to x and y axis with respect to a centre of mass of the non-vertical objects; e) classifying the pedestrians in the image based on their shapes; and f) tracking a movement of the classified pedestrian using a mean shift algorithm.
