MATLAB: Problem in drawing projection profiles

image processingprojection profiles

I am trying to draw the projection profiles (horizontal and vertical). I wrote the following code which supposes to work correctly. but the results are not the one that I need. Image1 shows the image that I want to process. Image2 shows the Vertical projection of image1 that produced by the code. Image3 shows the correct projection that I should get.
    binaryImage = imread(imgFullFileName);
    verticalProfile = sum(binaryImage, 1);
    horizontalProfile = sum(binaryImage, 2);
    [rows, columns] = size(binaryImage);
    vertProjImage = area(1:columns,verticalProfile,'FaceColor','k');
image1:
image2:
image3:

Best Answer

I think using bar() and barh() will solve the problem:
    binaryImage = imread(imgFullFileName);
    verticalProfile = sum(binaryImage, 1);
    horizontalProfile = sum(binaryImage, 2)
    [rows, columns] = size(binaryImage);
    horzProjImage = barh(horizontalProfile,1,'facecolor','black');
    verProjImage = bar(verticalProfile ,1,'facecolor','black');
