English Abstract
Traditional background subtraction algorithms are used mainly to discover objects in images by subtracting them from known background images for same scenes excluding these objects.
However, these traditional algorithms fail in detecting all edge pixels, which is in turn influences the accuracy of resulted detected objects.
Therefore, this thesis introduces an enhancement for the traditional background subtraction algorithms, considering applying two techniques within segmentation tool; coplanar filter; to improve the detection of all edge pixels, and Quadtree Decomposition; to divide images into homogenous blocks.
Both algorithms; the enhanced, and traditional are then applied to design a car tracking system using MATLAB to detect and count the number of cars in a specific street.
The number of detected cars resulted using each algorithm is compared later with the actual number of cars in that street for performance evaluation purposes.
The evaluation is conducted based on detecting and counting the number of cars both in; video frames within the online stage or uploaded images from a dataset within the offline stage.
After that, comparing these frames (images) with a background image for a street, which is devoided of cars.
The threshold of the proposed system will be adaptive over each segment of the image, normally threshold for traditional background subtraction is 0.5 where any pixel value greater than 0.5 assumed to be white while lower than 0.5 is assumed to be black.
This research results illustrate that the enhanced background subtraction algorithm outperforms the traditional algorithm in counting the number of cars in all frames.
This system achieved 47.01% average X accuracy rate for the traditional background subtraction algorithm and 81.19% average accuracy rate for the enhanced algorithm.
