Abstract
Official abstract text for this publication.
A cost effective method for detecting, classifying and tracking the pedestrian present in front of the vehicle by using images captured by near infrared (IR) camera disposed on the vehicle, the said method comprises the processor implemented steps of: detecting the road to focus of attention for filtering the region of interest (ROI) objects in the said image by estimating the ground region characterized by identifying smooth regions connected to bottom most part of the image; eliminating the non-ground objects based on their distance to ground; filtering the non-ROI objects based on the shape of such objects by computing the signal to noise ratio (SNR) which is a measure of regularity of the component based on its periodicity of its contour for each of such non-ROI objects; eliminating the non-vertical objects by computing inertial moment relative to x and y axis with respect to the centre of mass of such non-vertical objects; classifying the pedestrians in the analyzed frame of the image based their shape; and tracking the movement of the classified pedestrian using mean shift algorithm.
First claim
Opening claim text (preview).
We claim: 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-groun…
