How to use dataset_slam? [closed]

edit

,ı use ros-indigo and ubuntu 14.04. I try to run lsd_slam with an image folder. These images was taken from my tablet. This image folder is on my desktop.

I opened a terminal and run below command :

roscore

I opened a new terminal and run it :

rosrun lsd_slam_core dataset_slam _files:=...../Desktop/grayImages _hz:=0 _calib:=pinhole_example_calib.cfg

This command's output is :

/lsd_slam/lsd_slam_core/calib/pinhole_example_calib.cfg ... found!

But I don't see any window, map etc.

Content of pinhole_calib.cfg :

0.825 1.1 0.5 0.5 0

What is the problem? How can I run lsd_slam using image dataset?
