Hi Image Analyst,

Thanks a lot for your reply. Have a look at my input images at

My objective is to make a point cloud of the entire feet scan.
Please correct my understanding and suggest on processing the image to my final goal;
1. Isolating the laser trace in entire images
2. Acquiring point clouds and placing them in a metric graph, so that i could measure parameters.
