Hi all, I have developed some code for counting number of objects in image. But it is giving total number of objects in a image. I need to count number of cars or bikes separately.Here I am attaching code for counting objects. Please guide me in counting of cars or bikes. Thanks in advance.
clc;
clear all;
MV = imread('cars1.png'); %To read image
MV1 = imread('backgnd.png');
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

There are demos for that in the Computer Vision System Toolbox. Check online for them.

You just had to go to Products and select the Computer Vision System Toolbox, and then click the Code Examples link:
