Saved image

When you use a camera as the video source for the experiment, you may need to create or modify the arena or the areas of interest without being able to view the image directly from the chosen webcam (for example if you are using a computer that is not the one that will be used to make the acquisitions). For this you can use a "saved image" to replace the camera image and allow you to draw your arena and zones of interest. The saved image can also be modified during the experiment, for example: to create a zone of interest around a new object if it was not present when the protocol was created.

To create a saved image from the webcam :

Click on the corresponding button in the 'Video source' tab of the Protocol:

To create a saved image from an existing test or a file :

Click on the corresponding button in the 'Video source' tab of the Protocol to open the "saved image" dialog box :

"Saved image" dialog box :

You can select an image from:

the current test video.

an image or video file on your computer.

a video already recorded in the experiment.

the video of a test already recorded.

If the image is from a video, you can use the navigation bar above the video to select the desired image before clicking the "Ok" button.

The format of the selected image must be compatible with that of the video source of the protocol. That is to say that the ratio width / height must be identical. If the dimensions of the chosen image are different from those of the video source, the image will be resized.
