In matlab, how to draw a grid over an image

Question

How to draw a grid over an image. It should become part of that image itself. It should be able to show some rows and columns over the image itself. The lines for rows and c

Answer 1

Actually I watched this question after doing this code by my own .... the code reads an image and draw grid on the image every input parameter

I hope it would do any good :)

Watch the matlab code :

function [ imageMatdouble ] = GridPicture( PictureName , countForEachStep )
 %This function grid the image into counts grid 
pictureInfo = imfinfo(PictureName);     %load information about the input 

 [inputImageMat, inputImageMap] = imread(PictureName);        % Load the image     

 if (pictureInfo.ColorType~='truecolor')
    warning('The function works only with RGB (TrueColor) picture');
    return 
 end

%1. convert from trueColor(RGB) to intensity (grayscale)
 imageMat = rgb2gray(inputImageMat);   

%2. Convert image to double precision.
 imageMatdouble =im2double(imageMat);  

 % zero is create indicated to black 
 height = pictureInfo.Height ; 
 width = pictureInfo.Width
  i=1;j=1;  
 while (i<=height ) 
     for j=1:width
         imageMatdouble(i,j)=1;
    end
    j=1;
    if (i==1)
       i=i+countForEachStep-1;
   else 
       i=i+countForEachStep;
   end
  end


   i=1;j=1;  
  while (i<=width ) 
  for j=1:height
      imageMatdouble(j,i)=1;
   end
  j=1;
  if (i==1)
      i=i+countForEachStep-1;
  else 
       i=i+countForEachStep;
   end

 end

 imwrite(imageMatdouble,'C:\Users\Shahar\Documents\MATLAB\OutputPicture.jpg')
