20110249910 | IMAGE QUALITY ASSESSMENT INCLUDING COMPARISON OF OVERLAPPED MARGINS - Image quality is assessed for a digital image that is a composite of tiles or other image segments, especially focus accuracy for a microscopic pathology sample. An algorithm or combination of algorithms correlated to image quality is applied to pixel data at margins where adjacent image segments overlap and thus contain the same content in separately acquired images. The margins may be edges merged to join the image segments smoothly into a composite image, and typically occur on four sides of the image segments. The two versions of the same image content at each margin are processed by the quality algorithm, producing two assessment values. A sign and difference value are compared with other image segments, including by subsets selected for the orientation of the margins on sides on the image segments. The differences are mapped to displays. Selection criteria determine segments to be re-acquired. | 10-13-2011 |
20120127297 | DIGITAL MICROSCOPY WITH FOCUS GRADING IN ZONES DISTINGUISHED FOR COMPARABLE IMAGE STRUCTURES - Digital image quality is assessed, especially focus accuracy for a microscopic pathology sample image, using quality assessment criteria that differ among zones distinguished by a structural classification process. An image or area is divided into sub-regions such as adjacent pixel blocks. At least one metric or algorithm is applied, such as a Brenner gradient correlated with focus quality or a Laplacian transform correlated with structural difference. Spatial zones are distinguished by associating blocks of pixels that produced comparable values from the metric. The quality results of an objective metric such as the Brenner gradient are graded separately using statistical or pass/fail grading criteria in each spatial zone, independent of other zones. Focus quality across the image is mapped for display and/or used to queue a re-imaging step. | 05-24-2012 |
