Abstract

A method for recommending places to visit, included using a processor to provide the following steps: assembling a collection of images, wherein each image has first and second tags with the first tag corresponding to the location where the image was taken, and the second tag corresponding to subject matter of the image; clustering the images in response to the first tags into a plurality of locations; using the images in each location to produce at least one representative image of the location; using the second tags of images of each location to produce a list of representative keywords for each location; providing a query in the form of an image or subject matter, or both; and using the query in the form of an image to search among the representative images to recommend a location to visit, or using the query in the form of subject matter to search among the keywords to recommend a location to visit.

Claims

1. A method for recommending places to visit, comprising using a processor to provide the following steps:

a) assembling a collection of images, wherein each image has first and second tags with the first tag corresponding to the location where the image was taken, and the second tag corresponding to subject matter of the image;

b) clustering the images in response to the first tags into a plurality of locations;

c) using the images in each location to produce at least one representative image of the location;

d) using the second tags of images of each location to produce a list of representative keywords for each location;

e) providing a query in the form of an image or subject matter, or both; and

f) using the query in the form of an image to search among the representative images to recommend a location to visit, or using the query in the form of subject matter to search among the keywords to recommend a location to visit.

2. The method of claim 1 wherein the first tag includes longitude and latitude information of a location, and the step b) includes:

i) using the longitude and latitude for each location as features; and

ii) applying a mean shift clustering algorithm on the features to cluster the images into a plurality of locations.

3. The method of claim 1 wherein the step c) includes:

i) extracting visual features from the images in each location;

ii) clustering based on the extracted visual features of the images in each location into a plurality of groups wherein each group includes visually similar images; and

iii) producing a representative image for each group of visually similar images.

4. The method of claim 1 wherein step f) includes providing a plurality of recommended locations, and one or more images corresponding to each recommended location.

5. The method of claim 4 wherein the one or more images corresponding to each recommended location are representative images, or selected from the corresponding image clusters.

6. The method of claim 4 further including:

g) providing a map indicating the plurality of recommended locations.
