I created very high dense point cloud of some forest plots using terrestrial laser scanner. Then removed points above 1.3 meter to see the coarse woody debris (Fallen dead trees). Attached is the shaded DEM of the sample plot with coarse woody debris inside red ellipse.
Plot also consists of small trees, part of the stems of trees below 1.3 meter, ground and small rocks. From the image woody debris is discernible with its continuous shape. I am looking for the tool to extract woody debris from this image. Arcmap, Envi or any open source software would be perfect, and I also have basic Python knowledge if coding is helpful.
