IMAGE ANALYSIS BY OBJECT ADDITION AND RECOVERY
First Claim
Patent Images
1. A method for detecting an object in an image, the method comprising:
- obtaining one or more real images;
analyzing the one or more real images and deriving a set of parameters defining each of the one or more real images;
creating a modified image by inserting at least one artificial object into at least one of the one or more real images, the artificial object comprising at least a portion of an object identified in the one or more real images;
analyzing the modified image to derive a set of parameters defining the modified image;
comparing the set of parameters defining each of the one or more real images with the set of parameters defining the modified image;
determining the likelihood of the object being present within the one or more real images based on the set of parameters;
repeating the steps of analyzing, comparing, and determining; and
stopping the steps of analyzing, comparing, and determining when the probability of additional, unidentified objects being present in the one or more real images has met a predetermined level.

Abstract
The invention described herein is generally directed to methods for analyzing an image. In particular, crowded field images may be analyzed for unidentified, unobserved objects based on an iterative analysis of modified images including artificial objects or removed real objects. The results can provide an estimate of the completeness of analysis of the image, an estimate of the number of objects that are unobserved in the image, and an assessment of the quality of other similar images.

21. A system comprising:
-
at least one detector for obtaining at least one real image; a processor; and a non-transitory, processor-readable storage medium in communication with the processor, wherein the non-transitory, processor-readable storage medium comprises one or more programming instructions that, when executed, cause the processor to; direct the at least one detector to obtain one or more real images; analyze the one or more real images and derive a set of parameters defining each of the one or more real images; create a modified image by inserting at least one artificial object comprising at least a portion of an object identified in the one or more real images into at least one of the one or more real images; analyze the modified image to derive a set of parameters defining the modified image; compare the set of parameters defining each of the one or more real images with the set of parameters defining the modified image; determine the likelihood of the object being present within the one or more real images based on the set of parameters; repeat the steps of analyzing, comparing, and determining; and stop the steps of analyzing, comparing, and determining when the probability of additional, unidentified objects being present in the one or more real images has met a predetermined level.
