Abstract (en)
[origin: WO2017055250A1] The invention concerns a method for searching for images similar to a query image (Ir) in a collection of images, said method using a representation of the query image in the form of a vector of characteristics allocating a weight to each of the characteristics, and comprising a step of querying (LTU) an inverted index (II) matching each of the characteristics (C1-C5) with images from the collection (I6-I8, I1-I2), characterised in that the step of querying the inverted index comprises an operation of integrating, into a list, one or more images (I6-I8) from the collection that are matched in the inverted index with a first characteristic (C3) selected depending on the weight allocated to same in the vector representing the query image, the operation of integrating into the list being repeated for another characteristic (C1) selected depending on the weight allocated to same in the vector representing the query image until the number of images of the collection integrated into the list reaches a target number.
