This Go library allows you to perform a visual query on a set of images, returning the results in the order of similarity. This allows you to effectively detect duplicates with minor modifications (e.g. some colour correction or watermarks).

It is an implementation ofFast Multiresolution Image Querying by Jacobs et al. which uses truncated Haar wavelet transforms to create visual hashes of the images. The same method has previously been used in theimgSeek software and theretrievr website.

go get github.com/rivo/duplo

import"github.com/rivo/duplo"// Create an empty store.store:=duplo.New()// Add image "img" to the store.hash,_:=duplo.CreateHash(img)store.Add("myimage",hash)// Query the store based on image "query".hash,_=duplo.CreateHash(query)matches:=store.Query(hash)sort.Sort(matches)// matches[0] is the best match.
