SYSTEM AND METHOD FOR DETECTING OUTLIERS
A system and method for detecting outliers. A method may include selecting, from a first subset of digital objects, a second subset of digital objects, sorting the first subset of digital objects according to a similarity to at least some of the objects included in the second subset, and, designating at least one digital object included in the first subset as an outlier based on the sorting. A similarity value indicative of a level of similarity between an object and a reference object may be associated with the object. A set of objects may be sorted according to their associated similarity values.
1 . A method of identifying outliers, the method comprising:
selecting, from a first subset of digital objects, a second subset of digital objects;
sorting the first subset of digital objects according to a similarity to at least some of the objects included in the second subset; and
designating at least one digital object included in the first subset as an outlier based on the sorting.
2 . The method of claim 1 , comprising defining the first subset by:
associating with each digital object included in a set of digital objects a value according to a similarity between the digital object and an input digital object;
sorting the set of digital objects according to their associated values; and
selecting the first subset from the set of digital objects, based on the sorting.
3 . The method of claim 1 , comprising associating with each digital object included in the first subset a cumulative value according to a similarity between the digital object and each of the digital objects included in the second subset and sorting the first subset according to the cumulative values.
4 . The method of claim 1 , wherein the digital objects contain digital images.
5 . The method of claim 1 , comprising presenting at least some of the digital objects to a user according to the sorting.
6 . The method of claim 3 , wherein the a measure of a similarity between digital images is based on a location of the digital images in a space and wherein the dimensions of the space include at least one imaging parameter included in the list consisting of: a color distribution, a hue, an intensity, a brightness, a luminance, a chromaticity and a saturation.
7 . An article comprising a non-transitory computer-readable storage medium, having stored thereon instructions, that when executed on a computer, cause the computer to:
select, from a first subset of digital objects, a second subset of digital objects;
sort the first subset of digital objects according to a similarity to at least some of the objects included in the second subset; and
designate at least one digital object included in the first subset as an outlier based on the sorting.
8 . The article of claim 7 , wherein the instructions when executed further result in defining the first subset by:
associating with each digital object included in a set of digital objects a value according to a similarity between the digital object and an input digital object;
sorting the set of digital objects according to their associated values; and
selecting the first subset from the set of digital objects, based on the sorting.
9 . The article of claim 7 , wherein the instructions when executed further result in associating with each digital object included in the first subset a cumulative value according to a similarity between the digital object and each of the digital objects included in the second subset and sorting the first subset according to the cumulative values.
10 . The article of claim 7 , wherein the digital objects contain digital images.
11 . The article of claim 7 , wherein the instructions when executed further result in presenting at least some of the digital objects to a user according to the sorting.
12 . The article of claim 9 , wherein the a measure of a similarity between digital images is based on a location of the digital images in a space and wherein the dimensions of the space include at least one imaging parameter included in the list consisting of: a color distribution, a hue, an intensity, a brightness, a luminance, a chromaticity and a saturation.
