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

A = double(rgb2gray(MV));%convert to gray B= double(rgb2gray(MV1));%convert 2nd image to gray [m1,n1,p1] = size(A) ; [m2,n2,p2] = size(B) ; m = max(m1,m2) ; n = max(n1,n2) ; A = imresize(A,[m n]) ; B = imresize(B, [m n]) ;
