sir I want to convert my .m file to VHDL . my code is given below.

function veh
clear all;

close all;
a=imread('veh.png');
%a=rgb2gray(a);
imshow(a)
a=double(a);
b=imread('back.png');
%b=rgb2gray(b);
figure
imshow(b)
b=double(b);
for i=1:250
    for j=1:400
       sub(i,j)=abs(a(i,j)-b(i,j));
     end
end 

for i=1:250
    for j = 1:399
        dxSImg(i,j) =abs(sub(i,j+1)) -abs(sub(i,j));
    end
end
for i = 1:249
    for j =1:399
        dySImg(i,j) =sub(i+1,j)-sub(i,j);
    end
end
for i = 1:249
    for j = 1:399
        dfSImg(i,j) =abs(dxSImg(i,j))+abs(dySImg(i,j));
    end
end
figure
imshow(dfSImg)
sum = 0;
Th = 0;
for i = 1:249
    for j = 1:399

         x(i,j) = mean(dfSImg(i,j));
         y(i,j) = std(dfSImg(i,j));
         Th = Th + x(i,j)+3*y(i,j);

      end
  end
  for i = 1:249
      for j = 1:399

          if dfSImg(i,j)>=85
              bwdSImg(i,j) = 1;
          else
              bwdSImg(i,j) = 0;
          end
      end
  end

        figure
        imshow(bwdSImg)
        cc = bwconncomp(bwdSImg);

        for j = 1:399
           Lveh = max(bwdSImg(i,j));
        end

        for i = 1:249
            Hveh = max( bwdSImg(i,j));
        end
        rImg = imread('frame.png');
        for i = 1:385
            for j = 1:640
                sl = 250*i;
                sh = 250*i+400;
                tl = 400*j;
                th = 400*j+250;

         for s = sl:sh
            for t =tl:th
                cImg(i,j) =  rImg(s,t)/(400*250);

            end
         end
            end
        end

        virtualRow(j) =  0;
        for i= 1:249
            virtualRow(j) =virtualImage(j)+bwdSImg(i,j);
        end
        virtualCol(i) = 0;
        for j=1:399
            virtualCol(i) = virtualCol(i)+ bwdSImg(i,j);
        end

You need to break the design into two parts. A testbench and a design.

Follow basic example shown here.
