Patent ID: 8218877

Claim:
A new method of tracking a vehicle using image processing, comprising: establishing background information of a color image; retrieving first instant detecting image information; calculating said background information of said color image and color intensity information of said first instant detecting image information, wherein said color intensity information is a maximum value of a statistical quantity including a gray intensity and a branched color intensity by a Sum of Absolute Difference method; adjusting said first instant detecting image information, wherein when an automatic white balance function is activated, luminance is adjusted by said color intensity information; calculating a dynamic adjustment value of color intensity of said background information including said gray intensity and said branched color intensity, wherein said dynamic adjustment value of color intensity comprises a corresponding difference value in a maximum value of a difference value statistical amount; calculating moving object information including real objects and noise, wherein first moving object information is obtained by calculation of a dynamic critical value; comparing and extracting said moving object information by using a horizontal and vertical projection amount and edge feature to obtain real information of said moving object; calculating a grey characteristic of said moving object information and said background information of a color image to judge a shadow part of said moving object information, and subtracting said shadow part by using said moving object information leaving a second moving object information; and tracking said second moving object information.
