| Can I use CM-IR if I am not a programmer? |
| Definitely. CM-IR is delivered with a ready-to-use application called Easy_Video_Trainer. You can teach what you want to recognize, monitor the results of the recognition on screen and when satisfied with the results save the knowledge to the Flash memory of the CM-IR board. You can then disconnect the board from your PC and connect it to an external power supply so it resumes recognition autonomously. Note that the default configuration of the board monitors a fixed single region of interest. If your application requires scanning, tracking or more, contact Recognetics to obtain a list of partners whom can help you with the programming of the board. |
| What is the difference between Easy_Video_Trainer and Easy_Image_Trainer? |
Easy_Video_Trainer is intended for use with CM-IR or CM_EB connected to a compatible video sensor. This application lets' you send teaching commands to the board and read the results of the recognition. It only acts as a user interface and all operations are actually executed on the board, including the extraction of the signature vectors from the video and their transmission in real-time to the neurons.
Easy_Image_Trainer is intended to simulate the behavior of the CogniMem chip on a PC. The interface looks very similar to Easy_Video_Trainer and knowledge file (*.ckf) can be exchanged between the two applications. Easy_Image_Trainer can be convenient if you have collected many images with Easy_Video_Trainer and want to teach and validate your training at a different time or location on your PC. |
| Does the CogniMem chip learns the entire image? |
| Yes, a color sensor may be interfaced with CM-EB. However please note that the recognition engine built into the CogniMem chip extracts a monochrome feature from the video image. This means that the display may appear in color but the recognition will be based on the luminosity only. If the color information is critical to your application, the extraction of a color signature can be programmed in the FPGA of the CM_EB board and send to the neurons in "Bypass" mode instead of "Video" mode. |
| Can I do target tracking with CM-IR? |
| Yes. A simple demonstration of target tracking can be made with Easy_Video_Tracker by learning a known target at 3 different positions within a region of interest centered in the field of view: (1) target is centered, (2) shifted to the right, (3) shifted to the left. When the recognition logic of the CogniMem chip is active, the recognized category is transmitted to the GPIO lines at frame rate. This means that a motion controller properly interfaced with CM_IR (both mechanically and electronically) could always re-center the target to be in the middle of the field of view. |
