First Claim
Patent Images
1. A first device comprising:
- one or more processors to;
obtain a video frame, comprising images in sequence, from a second device under test;
select a filter configuration, of a plurality of filter configurations, for at least one filter;
filter an image included in the images in sequence using the filter configuration to generate a filtered image;
identify text from the filtered image;
compare the text identified from the filtered image and an expected result;
determine a filter performance for the filtered image based on comparing the text identified from the filtered image and the expected result; and
determine a suitable filter configuration based on determining the filter performance.

1. A first device comprising:
-
one or more processors to; obtain a video frame, comprising images in sequence, from a second device under test; select a filter configuration, of a plurality of filter configurations, for at least one filter; filter an image included in the images in sequence using the filter configuration to generate a filtered image; identify text from the filtered image; compare the text identified from the filtered image and an expected result; determine a filter performance for the filtered image based on comparing the text identified from the filtered image and the expected result; and determine a suitable filter configuration based on determining the filter performance. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions that, when executed by one or more processors, cause the one or more processors to; obtain a video frame, comprising a plurality of images, from a device under test; select a filter configuration for a plurality of filters; filter an image included in the plurality of images using the filter configuration to generate a filtered image; identify text from the filtered image; compare the text identified from the filtered image and an expected result; determine a filter performance for the filtered image based on comparing the text identified from the filtered image and the expected result; and determine a suitable filter configuration based on determining the filter performance. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method comprising:
-
obtaining, by a first device, a video frame, comprising images in sequence, from a second device under test; selecting, by the first device, a filter configuration, of a plurality of filter configurations, for one or more filters; filtering, by the first device, an image included in the images in sequence using the filter configuration to generate a filtered image; identifying, by the first device, text from the filtered image; comparing, by the first device, the text identified from the filtered image and an expected result; determining, by the first device, a filter performance for the image based on comparing the text identified from the filtered image to the expected result; and determining, by the first device, a suitable filter configuration based on determining the filter performance. - View Dependent Claims (16, 17, 18, 19, 20)
