MATLAB: How to detect the objects from a video

image processingvehicle counting

I have tried to convert the video into frames. And then to a binary images where the object is identified as a white patch,but I couldn't count the the objects. Moreover our project is based on the vehicle counting system using a ip camera. I dont have computer vision toolbox in matlab. Kindly,reply me back. This is the code,I have done so far,
        **clc
clear all
% Read movie
SF = 1; %Starting Frame
MV = mmreader('a.avi'); %To read Movie EF = MV.NumberofFrames ; %Ending Frame img = read(MV,1); %reading particular frame A = double(rgb2gray(img)); %motion vector works on Gray Image formate [height width] = size(A); %Movie size?
% motion estimation h1 = figure(1); for f = SF: EF %Frame from SF To EF B = A; img = read(MV,f); A = double(rgb2gray(img));
    %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(img), title (['Orignal Sequence Frame#',int2str(f)]);
    subplot(2,2,2) , imshow(mat2gray(A)), title ('Previous Frame');
    subplot(2,2,3) , imshow(mat2gray(B)), title ('Next Frame');
    sd=imadjust(fg);
    level=graythresh(sd);
    m=imnoise(sd,'gaussian',0,0.025);
    k=wiener2(m,[5,5]);
    bw=im2bw(k,level);
    subplot(2,2,4) , imagesc(bw), title ('Foreground');
    hold off;
    pause (.1);
% saveas(h1,strcat('Result-Paris-',num2str(f)),'jpg');
end**

Best Answer

can you post a clearly intended code. Have you decided on an algorithm to binarize you input frames ?
One way to count targets can be to identify the maximum intensity point in the frame and find the connected region.
