What term refers to locating an object relative to the edge of the screen?

The term that refers to locating an object relative to the edge of the screen is known as pixel-based object location. This method involves identifying the specific coordinates of an object by evaluating the pixel positions on the screen. By referencing these coordinates, automation processes can accurately pinpoint where an object is located in relation to the boundaries of the display. This technique is particularly useful in environments where the position of graphical user interface elements may vary, as it allows for dynamic adjustment based on their actual display coordinates rather than relying on fixed locations.

The other options represent different techniques or concepts that are not specifically about locating objects relative to the edge of the screen. Image matching involves comparing a captured image against a known image to identify similarities and differences. Coordinate mapping pertains to establishing a relationship between different systems of coordinates, which is broader than just screen boundaries. Screen overlay detection typically refers to identifying elements layered on top of other screen objects rather than relating their positions to the screen edges directly.
