Appl. No.:

11/018840

International Classification:

G06K 9/00
G06K 9/40
G06K 9/54
G06K 9/60
G09G 5/00

H04N 5/202

US Classification:

382274, 382128, 382169, 382305, 345591, 348254

Abstract:

Methodologies and systems to compare images with different levels of contrast are provided. Contrast is normalized between the images with different contrast levels and brightness is set. When normalizing contrast a derivative of gray level is determined for a first digital image having a first contrast level, and a derivative of gray level is determined for a second digital image having a second contrast level that is greater than the first contrast level. A ratio of the derivative of gray level for the first digital image to the derivative of gray level for the second digital image is determined, and the derivative of gray level for the first digital image is equalized with the derivative of gray level for the second digital image. Brightness of at least one image may be set automatically, such as by calculating an average pixel value excluding background and text, or manually.

US Classification:

382274, 382128, 382168, 382176, 382190, 358462

Abstract:

Systems and methods of automatically adjusting brightness of a digital image are provided. A particular method includes accessing data including a first digital image and identifying text and background in the first digital image. The method also includes calculating an average pixel value exclusive of the text and the background for the first digital image. The method further includes adjusting a brightness setting associated with the first digital image based on the calculated average pixel value.

Appl. No.:

15/087579

Inventors:

- Chicago IL, US
Steven K. Brady - Renton WA, US
William D. Meade - Seattle WA, US
Thomas A. Maeder - Lake Forest Park WA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

G01N 23/04

Abstract:

A measurement system is provided that includes a radiographic source, a detector, and at least one processor. The at least one processor is operably coupled to the detector and configured to: position the radiographic source in a first position relative to the object to image a first portion of the object, with the first position configured to maintain parallax for the first portion within a predetermined amount; obtain first imaging information of the first portion of the object in the first position; adjust the position of the radiographic source relative to the object to a second position, with the second position configured to maintain parallax for the second portion within a predetermined amount; obtain second imaging information of the second portion of the object in the second position; and generate an image of the object using the first imaging information and the second imaging information.
