Method and device for seeking images based on the content taking into account the content of regions of interest
First Claim
1. Method of seeking images, from an example image containing a plurality of regions of interest, from amongst a plurality of images stored in a database, each of the stored images being associated with a data item of a first type, referred to as an index of the stored image, representing at least one characteristic of the visual content of the image, said method comprising the following steps:
- for each region of interest, receiving a data item of a second type indicative of a user selection for a type of taking into account of the content of said region of interest for the seeking of images;
calculating a data item of a third type, referred to as the index of the example image, representing at least one characteristic of the visual content of the example image, the structure of said data item of the third type and the method of calculating said data item of the third type depending on said data items of the second type;
selecting an image research strategy according to said data items of the second type;
calculating a similarity, according to the selected image research strategy, between the example image and each of the images amongst at least one subset of the stored images, said similarity being calculated from said data item of the first type associated with the stored image and the data item of the third type associated with the example image; and
supplying at least one image, referred to as the result image, in the database, said at least one result image being selected from amongst said stored images in the database according to its degree of similarity with said example image.

Abstract
A method of seeking images, from an example image, from amongst a plurality of images stored in a database, each of the stored images being associated with an index, representing at least one characteristic of the visual content of the image, includes the following steps: a step of receiving a data item of a second type representing the location of at least one region of interest in the example image; a step of receiving, for each region of interest, a data item of a third type indicating a type of taking into account of the content of the region of interest for the seeking of images; a step of calculating an index of the example image, representing at least one characteristic of the visual content of the example image, the method of calculating this index depending on the data item of the second type and the data items of the third type; a step of calculating a similarity between the example image and each of the images from amongst at least one subset of the stored images, this similarity being calculated from the index associated with the stored image and the index associated with the example image; and a step of supplying at least one image, referred to as the result image, of the database, this result image being selected from amongst the images in the database according to its degree of similarity with the example image.

Device for seeking images, from an example image containing a plurality of regions of interest, from amongst a plurality of images stored in a database, each of the stored images being associated with a data item of a first type, referred to as an index of the stored image, representing at least one characteristic of the visual content of the image, said device comprising:
-
means for receiving, for each region of interest, a data item of a second type indicative of a user selection for a type of taking into account of the content of said region of interest for the seeking of images; means for calculating a data item of a third type, referred to as the index of the example image, representing at least one characteristic of the visual content of the example image, the structure of said data item of the third type and the calculation of said data item of the third type depending on said data items of the second type; means for selecting an image research strategy according to said data items of the second type; means for calculating a similarity, according to the selected research strategy, between the example image and each of the images amongst at least one subset of the stored images, based on said data item of the first type associated with the stored image and on the data item of the third type associated with the example image; and means for supplying at least one image, referred to as the result image, in the database, based on a selection from amongst said stored images in the database according to a degree of similarity of said result image with said example image.
