Abstract

The present invention relates to a functionalized textile substrate with cyclodextrins and/or cyclodextrin derivatives and water- and/or oil-repellent agents, which combines the water- and/or oil-repellent functionality with odor-absorbing properties.

Claims

1. A method for determining parameters of eyeglasses lens the method comprising:

obtaining an image of a background object, whereby in at least a part of the image at least a part of the background object is captured as viewed through a lens of a pair of eyeglasses; and

analyzing said at least a part of the image and identifying a property of the lens;

wherein said analyzing comprises comparing two parts of the background object as captured in the image, only one of the two parts being a part captured through the lens.

3. The method of claim 1, wherein the analyzing comprises analyzing a color characteristic of the image by comparing a color characteristic between said two parts of the background object captured in the image and thereby identifying said property, whereby said property pertains to at least one of the group consisting of having a predefined coating and having a predefined filter.

5. The method of claim 1, wherein the property pertains to a driving compatibility of the lens.

7. The method of claim 1, wherein the property pertains to opacity of the lens.

8. The method of claim 1, further comprising identifying an assembly quality of the eyeglasses based on the analysis.

9. The method of claim 1, wherein the analyzing further comprises comparing sharpness between two parts of the background object as captured in the image, only one of the two parts being a part captured through the lens.

11. The method of claim 1, further comprising identifying a predefined deformation along a segment within the background object as captured in the image.

12. The method of claim 1, further comprising optimizing color selection for at least a part of the background object according to technical characteristics of an image capture device intended to be used for capturing the image, a device intended to be used for presenting the background object, or of both of the devices.

13. The method of claim 1, wherein the background object comprises a plurality of parts, each part having a respective, predefined color and a respective, predefined position within the background object, and the analyzing is based on the respective predefined color and position of at least one of the parts.

14. The method of claim 1, wherein the background object comprises a plurality of parts arranged around a center of the background object, each part having a respective, predefined color and a respective, predefined order of placement around the center, and the analyzing is based on the respective predefined order of placement and color of at least one of the parts.

15. The method of claim 1, further comprising for automatically identifying an orientation of the background object as captured in the image.

16. The method of claim 15, wherein said automatically identifying of the orientation of the background object captured in the image comprises using a directional aspect of a texture of the background object as captured in the image.

17. The method of claim 15, further comprising identifying alignment of the background object as captured in the image in a predefined orientation, and automatically initiating the analyzing upon the identifying of the alignment in the predefined orientation.

18. The method of claim 1, further comprising guiding a user in aligning the pair of eyeglasses and an image capture device used to capture the image with respect to each other.

19. The method of claim 18, further comprises at least one of the following:

locating a facial feature in the captured image, and using the located facial feature for said guiding of the user;

identifying alignment of the background object as captured in the image, and using the identified alignment for said guiding of the user locating a boundary of the lens in the image, and using the located boundary for said guiding of the user;

automatically estimating a location of a center of the lens of the eyeglasses in the image, and using the estimated location for said guiding of the user.

20. The method of claim 1, further comprising locating a boundary of the lens in the image.

22. The method of claim 20, further comprising verifying that the background object as captured in the image extends over two sides of the boundary.

23. The method of claim 1, further comprising automatically estimating a location of a center of the lens of the eyeglasses in the image.

6. (canceled)

10. (canceled)

21. (canceled)

24. (canceled)

25. A system for testing of eyeglasses using a background object, the system comprising:

a reference object image provider configured and operable for obtaining an image of a background object, whereby in at least a part of the image at least a part of the background object is captured as viewed through a lens of a pair of eyeglasses;

an image analyzer configured to analyze an image of a background object to determine at least said part of the image in which at least said part of the background object being captured in the image as viewed through the lens of the eyeglasses; and

a property identifier, in communication with the image analyzer, configured to identify a property of the lens based on the analyzed image by comparing two parts of the background object as captured in the image, only one of the two parts being a part captured through the lens.

26. A non-transitory computer readable medium storing computer executable instructions for performing steps of testing of eyeglasses using a background object, the steps comprising:

obtaining an image of a background object, whereby in at least a part of the image at least a part of the background object is captured as viewed through a lens of a pair of eyeglasses; and

analyzing said at least a part of the image and identifying a property of the lens based on the analyzing;

wherein said analyzing comprises comparing two parts of the background object as captured in the image, only one of the two parts being a part captured through the lens.
