How can I remove white lines which is larger then Threshold value in binary image ? (matlab)

Question

I have a binary image which I want to remove white lines larger then Threshold value (like 50 pixel).

original image:

input and output image :

My idea:

I want to count white pixels which located in each rows and if (( number of white pixel > threshold value )) then remove that line.

please Edit and complete my code.

  close all;clear all;clc;

  I =imread('http://www.mathworks.com/matlabcentral/answers/uploaded_files/34446/1.jpg');
  I=im2bw(I);
  figure,
  imshow(I);title('original');
  ThresholdValue=50;
  [row,col]=size(I);
  count=0;     % count number of white pixel
  indexx=[];   % determine location of white lines which larger..
  for i=1:col
      for j=1:row

          if I(i,j)==1
              count=count+1; %count number of white pixel in each line
        % I should determine line here
        %need help here
          else
              count=0;
              indexx=0;
          end
          if count>ThresholdValue
          %remove corresponding line
          %need help here
          end
      end
  end

Answer 1

There is only a small part missing, you must also check if you reached the end of the line:

    if count>ThresholdValue
        %Check if end of line is reached
        if j==row || I(i,j+1)==0
            I(i,j-count+1:j)=0;
        end
    end

Updated code regarding the comment:

I =imread(pp);
I=im2bw(I);
figure,
imshow(I);title('original');
ThresholdValue=50;
[row,col]=size(I);
count=0;     % count number of white pixel
indexx=[];   % determine location of white lines which larger..
for i=1:row %row and col was swapped in the loop
    count=0; %count must be retest at the beginning of each line 
    for j=1:col %row and col was swapped in the loop

        if I(i,j)==1
            count=count+1; %count number of white pixel in each line
            % I should determine line here
            %need help here
        else
            count=0;
            indexx=0;
        end
        if count>ThresholdValue
            %Check if end of line is reached
            if j==col || I(i,j+1)==0
                I(i,j-count+1:j)=0;
            end
        end
    end
end
imshow(I)
