You can set an object's properties to be identified by Image Recognition.
As this is an image based recognition, it is not recommended and should only be used only as backup.
To edit an element in the Object Repository:
Step 1: Right click to edit the element in the Object Repository.
Step 2: Go to the 'Image' tab.
Step 3: Choose the option on the Scanning Type drop-down list.
A pop-up box will appear in which you should click the "Image" tab. Then tick the "Enable" box.
Step 4: Click "OK". Now the 'Logout' Object will also be identified by Image Recognition.
