Photographing procedure

 

This App has been created for the purpose that visually impaired persons can choose the color and pattern of their clothes. As the result they can go out wearing the clothes with confidence.

In order to perform color recognition properly under different lighting environment, the color correction is needed. One of the methods of color correction is to photograph an object with a color-chart (referred to as a reference: color standards).

However, it is very inconvenient to use the reference when visually impaired persons use the App. So, aiming to achieve the correct color recognition with no reference, I have created this App using a unique color correction method. For this reason, there are certain restrictions on the photographing method. Please photograph clothes in the following procedure.

  The measurement processing range of clothes is a square of one side 18 cm. When photographing small clothes than this range such as socks and ties, consider that the background appears in the image, and the color and pattern of the background is also output.
• If you photograph shiny clothes, it may be stronger whitish because of the reflected flash light.
• When photographing a dark-colored clothing, it is desirable to photograph together by, for example, inserting the white clothing such as a handkerchief in the pocket.
