Abstract

An image processing method includes partitioning an image under test to form a plurality of contiguous image segments having similar image properties, deriving feature data from a subset including one or more of the image segments, and comparing the feature data from the subset of image segments with feature data derived from respective image segments of one or more other images so as to detect a similarity between the image under test and the one or more other images.

First claim

The invention claimed is:

1. An image capture device comprising:
a storage medium configured to store captured image data;
a display;
a user interface configured to receive a section of an area of an image from the image data when the image data is output to the display;
circuitry configured to
partition the image into image segments including at a least one segment corresponding the selected area of the image, each segment representing set of pixels having similar properties; and
derive a representation of at least the segment corresponding to the selected area of the image, the representation comprising quantized image data; and

a network interface configured to
transmit the representation of the segment corresponding the selected area of the image; and
receive data indicative of a purchasable article or service representing a match to a reference representation associated with a at least one purchasable article or service, wherein

the circuitry is configured to interpret the received data and output for display purchase details of the purchasable article or service.

2. The image capture device of claim 1 , wherein
the match is determined when a threshold of similarly between the representation of the segment and the reference representation exceed a predetermined threshold.

3. The image capture device of claim 1 , wherein
the representation comprises quantized image color data.

4. The image capture device of claim 1 , wherein
the representation comprises feature data representing quantized image color data and other properties of the segment.

5. The image capture device of claim 1 , wherein
the purchase details include data indicative of a price and a purchase control, and
the purchase control is executable in response to the user control.

6. A method comprising:
storing captured image data;
receiving a selection of an area of an image from the image data when the image data is displayed by a display;
partitioning the image into image segments including at a least one segment corresponding to the selected area of the image, each segment representing set of pixels having similar properties;
deriving a representation of at least the segment corresponding the selected area of the image, the representation comprising quantized image data;
transmitting the representation of the segment corresponding the selected area of the image;
receiving data indicative of a purchasable article or service representing a match to a reference representation associated with a at least one purchasable article or service; and
interpreting the received data and outputting for display purchase details of the purchasable article or service.

7. The method of claim 6 , wherein
the match is determined when a threshold of similarly between the representation of the segment and the reference representation exceed a predetermined threshold.

8. The method of claim 6 , wherein
the representation comprises quantized image color data.

9. The method of claim 6 , wherein
the representation comprises feature data representing quantized image color data and other properties of the segment.

10. The method of claim 6 , wherein
the purchase details include data indicative of a price and a purchase control, and
the method further comprises executing the purchase control in response to the user control.

11. The method of claim 6 , wherein
the reference representation is indicative of features of segments of a reference image.

12. The method of claim 6 , wherein
the purchase details include a hyperlink for the purchasable article or hyperlink.

13. A non-transitory computer readable medium including computer program instructions, which when executed by a computer causes the computer to perform the method of claim 6 .

14. A method comprising:
receiving first images and associated hyperlinks corresponding to purchasable items or services;
deriving reference feature data from the first images and storing the feature data on a non-transitory computer readable storage medium in association with the hyperlinks;
receiving feature data representing segments of second images via a network connection; and
comparing, by a computer, the received feature data with reference feature data, and where a similarity between the received feature data with the reference feature data is within a comparison threshold
providing the hyperlinks associated with the reference feature data via a network connection; and
receiving compensation dependent upon whether a user selects the hyperlinks provided via a network connection.

15. The method of claim 14 , wherein
the first images are received via the network connection.

16. The method of claim 14 , wherein
the deriving includes deriving reference feature data representing segments of the first images.

17. The method of claim 14 , wherein
the reference feature data represents segments of the first images, and
the comparing includes comparing the feature data representing the segments of the second image with the reference feature data representing segments of the first images.

18. The method of claim 16 , wherein
the comparing includes comparing the feature data representing segments of the second image with the reference feature data representing segments of the first images.

19. The method of claim 14 , wherein
at least one of the hyperlinks associated with the reference feature data is a hyperlink for purchasing a product or service associated with the reference feature data.

20. The method of claim 19 , wherein
the compensation is dependent upon whether the user purchases the product or service upon selecting the hyperlink for purchasing the product or service.

21. The method of claim 14 , wherein
at least one of the hyperlinks associated with the reference feature data is a hyperlink for processing a click-through payment for purchasing a product or service associated with the reference feature data.

22. The method of claim 21 , wherein
the compensation is dependent upon whether the user purchases the product or service upon selecting the hyperlink for processing the click-through payment for purchasing the product or service associated with the reference feature data.

23. One or more non-transitory computer-readable media including computer program code, which when executed by an information processing system, cause the information processing system to execute the method of claim 14 .
