 # tud_img_prep
-Set of tools for processing camera images. It is a ROS wrapper for comonly used OpenCv techniques including deinterlace of analog images and filtering.
+Set of tools for preprocessing a camera video feed using OpenCV.
+
+## Includes:
+
+* Deinterlacing of analog video signals,  e.g. video feed acquired using an Easycap USB capture card. Different interlacing methods:
+  * Half image
+  * Interpolation  (several interpolation methods)
+* Color format selection and conversion
+* Equalization of the images
+  * Manual equalization using brighness and contrast controls
+  * Automatic using OpenCV EqualizeHistogram function
+* Filtering
+  * Median
+  * Gaussian
+  * Bilateral Filter
+
+All the options can be changed in real time using Dynamic Reconfigure.
+
+## Installation
+Clone repository in your catkin worskspace:
+
+    cd ~/catkin_ws/src
+    git clone git@github.com:raultron/tud_img_prep.git
+
+Compile using catkin:
+
+    catkin build tud_img_prep
+
+
+## Usage
+
+    rosrun tud_img_prep img_prep
+
+This package requires ROS camera topics properly published.
+
+Default input topics:
+
+    /cam/image_raw
+    /cam/camera_info
+
+Default output topics:
+
+    /prep/cam/image_raw
+    /prep/cam/camera_info
+
+The default camera namespace can be changed using the parameter "camera_namespace" in a launch file or directly in the terminal.
+
+For example, if you have a camera that publishes in:
+
+    /my_camera/image_raw
+    /my_camera/camera_info
+
+Then the terminal command will be:
+
+    rosrun tud_img_prep img_prep _camera_namespace:=/my_camera
+
+And the ouput topics will be
+
+    /prep/my_camera/image_raw
+    /prep/my_camera/camera_info
