Thread: Connected Components not quite working

Ok see the attachments(note i have converted the images to gif as pgm is not allowed to be uploaded)

I am trying to do Connected Components Labeling in an image (Gaus.gif) and output the result (smallOut.gif)

It almost works except for one little part in the smallOut.gif. The first object from the left the top left of that object you will notice a dfferent color. Not sure why its doing that.
The link here Send big files the easy way. Files too large for email attachments? No problem! has all the files used to run the program, just run make and ./process

Could someone help please?

You are using an array to hold the data for the image, and processing on it is done from top left on down, right?

Your first references are probably incorrectly outside your array, or your values at that point, are not what you want.

Print out those first 20 values, and re-check your array bounds. If there's trouble with an array bound, it's nearly always right at the edges.
