Abstract

A method for generating the result of a search carried out using a search engine, in which a list of results is established after the search operation, the method including: identifying the thumbnail images associated with illustrated results from the list of results; carrying out an analysis operation of the images that includes comparing, by pairs, the identified thumbnail images; grouping, into image families, the thumbnail images sharing a similarity predetermined by the operation of comparing the thumbnail images; and generating the result of the search on the basis of the groupings into image families.

Claims

1. A method for generating the result of a search carried out using a search engine, in which a list of results is established after said search the method comprising:

identifying thumbnail type images associated with illustrated results from the list of results;

carrying out an analysis operation of the images that includes comparing, by pairs, the identified thumbnail type images;

grouping into image families the thumbnail type images sharing a similarity determined by comparing the thumbnail type images; and

generating the result of the search according to the groupings into image families.

2. The method according to claim 1, wherein the comparing is carried out with an encoder.

3. The method according to claim 2, wherein the encoder is of the H264 type.

4. The method according to claim 2, wherein the comparing carried out with the encoder comprises:

constituting all possible pairs of thumbnail type images (Bi, Bj) from the identified thumbnail type images;

for each pair of constituted images, encoding said pair of images with the encoder;

determining, from the encoding, variations between the two images from the pair of images;

quantifying the variations between the two images from the pair of images under consideration to obtain a quantification value;

if the quantification value of the pair of images under consideration is less than a previously determined variation threshold, grouping the two images from the image pair in a same image family.

5. The method according to claim 1, wherein, prior to carrying out the image analysis operation, said method comprises accessing a high-resolution image associated with each identified thumbnail, the image analysis then being carried out on the high-resolution images.

6. The method according to claim 1, wherein, prior to carrying out the image analysis operation, said method comprises converting the identified thumbnail type images into a same image format.

7. The method according to claim 6, wherein the image format in which the identified thumbnail type images are converted is the YUV format.

8. The method according to claim 1, wherein identifying the thumbnail type images associated with the illustrated results from the list of results is carried out on a previously determined number of results from said list of results.
