how to segment words in an image containing paragraph? Doubt in ur previous answer

Hi Image Analyst,

For the image as you discussed in earlier post,

In your code for segmenting lines,

 grayImage = imread('line.png');

 horizontalProfile = mean(grayImage, 1);

 darkColumns = horizontalProfile < 210; 

 labeledColumns = bwlabel(darkColumns);

 word3 = ismember(labeledColumns, 3); 

 wordNumber3 = grayImage(:, word3);

I'm unable to segment lines with this code.

the statement "darkColumns = horizontalProfile < 210; " gives zero column.

And when labeling such column doesn't give any result.

I tried changing threshold values. But I am getting stuck in labeling the columns. Can you please help me
