Techniques of digital media categorization are described. An exemplary technique can include receiving a plurality of media objects that includes a first media object and a second media object. Each media object may comprise one or more images. The exemplary technique can also include detecting a first feature in the first media object and a second feature in the second media object and determine that the first and second features are similar based on comparing the first and second features. Furthermore, the exemplary technique can include associating the first media object with the second media object based on metadata describing the first media object. The association can be performed based on the determined similarity. The exemplary technique can also include grouping the first and second media objects in response to the association. Other embodiments and/or techniques are possible.
