code to detection the cars this code not counting cars properly How do i make it count correct ?

clc
clear all
MV = imread('cars1.jpg'); %To read image
MV1 = imread('backgnd.jpg');
A = double(rgb2gray(MV));%convert to gray
B= double(rgb2gray(MV1));%convert 2nd image to gray
[height, width] = size(A); %image size?
h1 = figure(1);
 %Foreground Detection
 thresh=11;
 fr_diff = abs(A-B);
 for j = 1:width
 for k = 1:height
 if (fr_diff(k,j)>thresh)
 fg(k,j) = A(k,j);
 else
 fg(k,j) = 0;
 end
 end
 end
 subplot(2,2,1) , imagesc(MV), title (['Orignal Frame']);
 subplot(2,2,2) , imshow(mat2gray(A)), title ('converted Frame');
 subplot(2,2,3) , imshow(mat2gray(B)), title ('BACKGND Frame ');
36;
 sd=imadjust(fg);% adjust the image intensity values to the color map
 level=graythresh(sd);
 m=imnoise(sd,'gaussian',0,0.025);% apply Gaussian noise
 k=wiener2(m,[5,5]);%filtering using Weiner filter
 bw=im2bw(k,level);
 bw2=imfill(bw,'holes');
 bw3 = bwareaopen(bw2,5000);
 labeled = bwlabel(bw3,8);
 cc=bwconncomp(bw3);
 Densityoftraffic = cc.NumObjects/(size(bw3,1)*size(bw3,2));
 blobMeasurements = regionprops(labeled,'all');
numberofcars = size(blobMeasurements, 1);
 subplot(2,2,4) , imagesc(labeled), title (['Foreground']);
 hold off;
 disp(numberofcars);% display number of cars
 disp(Densityoftraffic);%display number of vehicles
