Abstract

Assessing the quality of an electronic image comprises determining a quality rating for the electronic image, associating image quality thresholds with purposes for electronic images, selecting the purpose that corresponds to the electronic image, identifying an image quality threshold associated with the selected purpose, and determining whether the quality rating meets the image quality threshold. The electronic image is suitable for its intended purpose if its quality rating meets the threshold.

determining whether the image confidence score meets or exceeds the image quality threshold; and

accepting the electronic image based on a determination that the image confidence score meets the image quality threshold.

13. The computer-implemented method according to claim 10, wherein said step of determining a usability of the electronic image comprises the steps of:

processing the electronic image by an image usability analysis engine;

determining an image confidence score based on a result of said processing step; and

determining a composite score based on the image quality value and the image confidence score.

14. The computer-implemented method according to claim 13, wherein said step of determining whether to accept the electronic image based on the usability of the electronic image comprises the steps of:

determining whether the composite score meets or exceeds the image quality threshold; and

accepting the electronic image based on a determination that the composite score meets the image quality threshold.

15. A computer-readable medium having computer-executable instructions for performing the computer-implemented method of claim 1.

16. A computer-implemented method for assessing the quality of an electronic image comprising the steps of:

determining on a computer a quality rating for the electronic image;

determining a selected purpose for the electronic image;

identifying an image quality threshold based on the selected purpose of the electronic image; and

determining whether the quality rating meets or exceeds the image quality threshold,
