Abstract
Official abstract text for this publication.
Methods and systems are presented for organizing images. In one aspect, a method can include generating a correlation value indicating a likelihood that a face included in a test image corresponds to a face associated with a base image, determining that a correlation threshold exceeds the correlation value and that the correlation value exceeds a non-correlation threshold, generating a similarity score based on one or more exposure values and one or more color distribution values corresponding to the test image and the base image, combining the similarity score with the correlation value to generate a weighted correlation value, and determining that the test image and the base image are correlated when the weighted correlation value exceeds the correlation threshold.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer program product, encoded on a non-transitory computer-readable medium, operable to cause data processing apparatus to perform operations comprising: generating a correlation value indicating a likelihood that a face included in a test image corresponds to a face associated with a pre-determined base image; determining that a correlation threshold exceeds the correlation value and that the correlation value exceeds a non-correlation threshold; confirming that an elapsed time between the base image and the test image is below a time threshold; generating a similarity score based on one or more exposure values and one or more color distribution values corresponding to the test image and the base image; combining the similarity score with the correlation value to generate a weighted correlation value; and determining that the test image and the base image are correlated when the weighted correlation value exceeds the correlation threshold. 2. The computer program product of claim 1 , further operable to cause data processing apparatus to perform operations comprising: determining the elapsed time based on time and date metadata associated with the base image and the test image. 3. The computer program product of claim 1 , further operable to cause data processing apparatus to perform operations comprising: applying a weighting factor to at least one of the one or more exposure values and one or more color distribution values. 4. The computer program product of claim 1 , further operable to cause data processing apparatus to perform operations comprising: adjusting the correlation threshold based on one or more previous correlation operations. 5. The computer program product of claim 1 , further operable to cause data processing apparatus to perform operations comprising: determining that the base image and the test image include multiple faces; and computing a color distribution comparison between a corresponding face region of the base image and the test image for use in generating the similarity score. 6. The computer program product of claim 1 , further operable to cause data processing apparatus to perform operations comprising: determining that a correlation between the base image and the test image represents a forbidden association; and prohibiting the correlation.
