Sure! just subscribe to the RGB image topic. Assuming you started the openni with

roslaunch openni_launch openni.launch

Just subscribe to /camera/rgb/image_raw topic. The sensor_msgs/Image messages you get can be easily converted to OpenCV with cv_bridge package.

Dear @sumanth, if this answer is satisfactory for you, please, mark it as correct. Also, it would be more appropriate to ask about the package for text extraction from images as a new question, as it could be helpful for other people. Thank you for helping us keep the forum organised.
