clear all; clc;
img = imread('asmfx.jpg');
[m,n,p] = size(img);
figure; imshow(img);
    [xreg yreg value] = ginput(1); 
    title(['Row',num2str(xreg),'Col',num2str(yreg)])
    if (length(xreg) < 1)

i want to snanning image with first set point with mouse like black rectangle. how can i scan up with row. and stop if value setpoint = 0. thanks before

      return%break
    end
    

   %% inisialisasi posisi awal 
   sisiKanan  = [xreg+10 yreg];
   sisiTengah = [xreg yreg];
   sisiKiri   = [xreg-10 yreg];
  %% scan tengah
  markedTengah = insertMarker(img,[xreg yreg],'star','color','r','size',5);
  
 for scanTengahY = xreg
  for scanTengahX = yreg : yreg-100
      %rr=[r(scanTengahX,scanTengahY),g(scanTengahX,scanTengahY),b(scanTengahX,scanTengahY)];
     if scanTengahX == sum(cumprod(a~=0))+1   
        break;
        markedTengah = insertMarker(img,[scanTengahX scanTengahY],'star','color','r','size',5);
        imshow(markedTengah); 
      end
   end
  end
      
%marked = insertMarker(img,[xreg yreg],'star','color','r','size',5);
