Method and apparatus for image contrast quality evaluation
First Claim
Patent Images
1. A method for measuring the contrast quality of an image comprising the steps of:
- (a) acquiring an image;
(b) operating on the image to compute a first edge intensity value; and
(c) operating on the image to compute an edge of edge intensity value; and
(d) computing an image contrast score for the image as the ratio of the edge of edge intensity value to the first edge intensity value.

Abstract
A method for single image based image contrast quality evaluation is used in a computer controlled image system including an automated microscope for acquiring images. An image is acquired. An image contrast score is computed for the image. An image reliability score is computed for the image. The image contrast score and image reliability score are accumulated and combined to produce a contrast quality score. The contrast quality score is compared to a predetermined limit so as to produce a quality of processing result.

14. A method for contrast quality evaluation of a biological specimen comprising the steps of:
-
(a) acquiring at least one image for a specimen; (b) computing at least one image contrast score for the at least one image; (c) computing at least one image reliability score for the at least one image; (d) accumulating and combining the at least one image contrast score and the at least one image reliability score to produce a quality of processing measure; and (e) comparing the quality of processing measure to a predetermined limit to produce a quality of processing result. - View Dependent Claims (15)

16. A method for single image based image contrast quality evaluation, comprising the steps of:
-
(a) acquiring an image; (b) detecting an edge gradient of the image to produce an edge gradient image; (c) processing the edge gradient image so as to produce an edge of edges image; (d) processing the edge gradient image so as to produce an accumulated edge intensity value; (e) processing the edge of edges image so as to produce an accumulated edges of edges intensity value; (f) computing an image contrast score for the image wherein the image contrast score comprises a ratio of the accumulated edges of edges intensity value to the accumulated edge intensity value; and (g) computing an image reliability score for the image wherein the image reliability score comprises the accumulated edge intensity value; and (h) combining the image contrast score and the image reliability score so as to produce a quality of processing measure.
