Abstract
A system may include a camera aimed at a display and configured to capture an image of the display, the display displaying a test image. The system may include a processor configured to: determine whether the display passes a verification test of correctly displaying a test image within a predetermined level of acceptance; and output a result of the verification test.
Claims20
A system, comprising:
- a camera aimed at a display and configured to capture an image of the display, the display displaying a test image;
- at least one processor configured to:
- receive the image from the camera;
- identify unique fiducial markers within the image;
- correct a perspective of the image to generate a corrected perspective image based at least on the unique fiducial markers;
- extract a widget region of interest from the at least one corrected perspective image, the widget region of interest being a region of interest where a widget is expected to or detected to reside;
- extract descriptors from the widget region of interest, the descriptors including at least one of:
- at least one color, at least one shape, or at least one character;
- compute similarity of the extracted descriptors against reference expected descriptor content;
- based on the computed similarity, determine whether the display passes a verification test of correctly displaying the test image within a predetermined level of acceptance;
- and
- output a result of the verification test.

The system of claim 13, wherein the at least one processor is further configured to:
- extract the widget region of interest from the at least one corrected perspective image based at least on at least one of the expected region of interest for the widget or by using objection detection to detect the widget.
A system, comprising:
- at least one processor configured to:
- receive an image from a camera, the camera aimed at a display and configured to capture the image of the display, the display displaying a test image;
- identify unique fiducial markers within the image;
- correct a perspective of the image to generate a corrected perspective image based at least on the unique fiducial markers;
- extract a widget region of interest from the at least one corrected perspective image, the widget region of interest being a region of interest where a widget is expected to or detected to reside;
- extract descriptors from the widget region of interest, the descriptors including at least one of:
- at least one color, at least one shape, or at least one character;
- compute similarity of the extracted descriptors against reference expected descriptor content;
- based on the computed similarity, determine whether the display passes a verification test of correctly displaying the test image within a predetermined level of acceptance;
- and
- output a result of the verification test.

A method, comprising:
- receiving, by at least one processor, an image from a camera, the camera aimed at a display and configured to capture the image of the display, the display displaying a test image;
- identifying, by the at least one processor, unique fiducial markers within the image;
- correcting, by the at least one processor, a perspective of the image to generate a corrected perspective image based at least on the unique fiducial markers;
- extracting, by the at least one processor, a widget region of interest from the at least one corrected perspective image, the widget region of interest being a region of interest where a widget is expected to or detected to reside;
- extracting, by the at least one processor, descriptors from the widget region of interest, the descriptors including at least one of:
- at least one color, at least one shape, or at least one character;
- computing, by the at least one processor, similarity of the extracted descriptors against reference expected descriptor content;
- based on the computed similarity, determining, by the at least one processor, whether the display passes a verification test of correctly displaying the test image within a predetermined level of acceptance;
- and
- outputting, by the at least one processor, a result of the verification test.
