Abstract
A comparison system includes a portable terminal including image capturing unit configured to capture a comparison image of a predetermined comparison region of a comparison object; and a server including comparison unit configured to compare the comparison object with a registered object on the basis of a statistical value for the luminance value of pixels in a registered image of the registered object, the pixels of the registered image existing at pixel positions corresponding to pixel positions estimated to be generating specular reflection in the comparison image captured by the portable terminal.
Claims20
A comparison system comprising:
- a portable terminal including a first processor configured to control an image capturing element and to obtain a comparison image of a predetermined comparison region of a comparison object, the object being any of televisions, personal computers, smartphones, bags, parts including fastening parts, screws, nails, gears, bearings, pipes, valves, shafts, semiconductor chips, commodity tags, parts made of plastic, ceramics and manufacturing product;
- and
- a server including a second processor programmed to compare the comparison object with a registered object on the basis of a statistical value for a luminance value of pixels in a registered image of the registered object, the pixels of the registered image existing at pixel positions corresponding to pixel positions estimated to be generating specular reflection in the comparison image captured by the portable terminal, and determine whether the comparison object and the registered object are identical by using the result of comparing.
A comparison apparatus comprising:
- a processor programmed to:
- receive an registered image of a registered object, the object being any of televisions, personal computers, smartphones, bags, parts including fastening parts, screws, nails, gears, bearings, pipes, valves, shafts, semiconductor chips, commodity tags, parts made of plastic, ceramics and manufacturing product;
- receive an image of a comparison object;
- compare the comparison object with the registered object on the basis of a statistical value for a luminance value of pixels in the registered image of the registered object, the pixels of the registered image existing at pixel positions corresponding to pixel positions estimated to be generating specular reflection in a comparison image of a predetermined comparison region of the comparison object;
- and
- determine whether the comparison object and the registered object are identical by using the result of comparing.
A comparison method comprising executing on a processor:
- receiving an registered image of a registered object, the object being any of televisions, personal computers, smartphones, bags, parts including fastening parts, screws, nails, gears, bearings, pipes, valves, shafts, semiconductor chips, commodity tags, parts made of plastic, ceramics and manufacturing product;
- receiving an image of a comparison object;
- comparing the comparison object with the registered object on the basis of a statistical value for a luminance value of pixels in the registered image of the registered object, the pixels of the registered image existing at pixel positions corresponding to pixel positions estimated to be generating specular reflection in a comparison image of a predetermined comparison region of the comparison object;
- and
- determining whether the comparison object and the registered object are identical by using the result of comparing.
A non-transitory computer readable storage medium storing a program causing a computer to execute comparison processing, wherein the processing comprises:
- receiving an registered image of a registered object, the object being any of televisions, personal computers, smartphones, bags, parts including fastening parts, screws, nails, gears, bearings, pipes, valves, shafts, semiconductor chips, commodity tags, parts made of plastic, ceramics and manufacturing product;
- receiving an image of a comparison object;
- comparing the comparison object with the registered object on the basis of a statistical value for a luminance value of pixels in the registered image of the registered object, the pixels of the registered image existing at pixel positions corresponding to pixel positions estimated to be generating specular reflection in a comparison image of a predetermined comparison region of the comparison object;
- and
- determining whether the comparison object and the registered object are identical by using the result of comparing.
