Abstract

Techniques are disclosed for ordering images. The technique includes receiving a request, the request including keywords and parameters specifying desired image characteristics. Further, the technique includes identifying a set of images responsive to the request based on a match of the keywords to tags associated with objects depicted in the set of images. Finally, the technique includes determining an ordering of the identified set of images by comparing the received parameters with metadata fields associated with respective tags of the objects and returning an indication of the set of images and the determined ordering of the images.

Claims

1. A computer-implemented method responding to an image search request, the method comprising:

receiving a request which includes one or more keywords and one or more parameters specifying desired image characteristics;

identifying, via one or more processors, a set of images responsive to the request based on a match of the keywords to image tags, wherein each image tag is associated with one of a plurality of objects which is depicted in one of the images from the set of images;

determining an ordering of the identified set of images by comparing the received parameters with corresponding tag metadata fields, each tag metadata field being distinct from and associated with one of the image tags; and

returning an indication of the set of images and the determined ordering of the images,

wherein each tag metadata field has a numerical value, the numerical value being determined as a relative value of a given image characteristic of one of the objects as depicted in one of the images when compared to the given image characteristic of the one of the objects as depicted in a plurality of images of an image repository, and

wherein determining the ordering of the identified set of images comprises;

comparing the received parameters with the corresponding tag metadata fields to determine whether predefined threshold values are met;

for each of the predefined threshold values that is met, increasing a weight value for the image tag to which the corresponding tag metadata field is associated; and

ordering the set of images based on at least the weight values for the image tags associated with the images in the set of images.

2. The computer-implemented method of claim 1, wherein a first one of the tag metadata fields represents a relative size of one of the objects.

3. The computer-implemented method of claim 1, wherein a first one of the tag metadata fields represents a relative focus of one of the objects.

4. The computer-implemented method of claim 1, wherein a first one of the tag metadata fields represents a relative contrast of one of the objects.

5. The computer-implemented method of claim 1, wherein a first one of the tag metadata fields represents a relative isolation of one of the objects.

6. The method of claim 1, wherein the set of images includes at least one dynamic image or a video sequence itself comprising a plurality of images.

7. A computer-implemented method for ordering a set of images, the method comprising:

determining, via one or more processors, an order for the set of images based at least on a comparison of values of one or more object image characteristic parameters with values of one or more tag metadata fields, wherein each tag metadata field is distinct from and associated with one of a plurality of image tags, each image tag being associated with an object depicted in one of the images from the set of images; and

in response to a request to view the set of images, presenting one or more images of the set of images in the determined order,

wherein each tag metadata field has a numerical value, the numerical value being determined as a relative value of a given image characteristic of one of the objects as depicted in one of the images when compared to the given image characteristic of the one of the objects as depicted in a plurality of images of an image repository, and

wherein determining the ordering of the identified set of images comprises;

comparing the received parameters with the corresponding tag metadata fields to determine whether predefined threshold values are met;

for each of the predefined threshold values that is met, increasing a weight value for the image tag to which the corresponding tag metadata field is associated; and

ordering the set of images based on at least the weight values for the image tags associated with the images in the set of images.

8. The computer-implemented method of claim 7, wherein the set of images is stored locally.
