APPARATUS AND METHOD FOR COLOR RESTORATION

Provided is a method and apparatus for restoring color of an input image. The method includes: separating multiple band information of a near infrared (NIR) channel from information of the input image by using a correlation between a color channel and the NIR channel in the input image; obtaining es...

More Information
Summary:Provided is a method and apparatus for restoring color of an input image. The method includes: separating multiple band information of a near infrared (NIR) channel from information of the input image by using a correlation between a color channel and the NIR channel in the input image; obtaining estimated invisible light band information of the NIR channel from the multiple band information of the NIR channel and estimated multiple band information of the NIR channel which is estimated from the color channel; estimating invisible light band information of the color channel based on the estimated invisible light band information of the NIR channel; and restoring a visible light band image of the color channel by removing the estimated invisible light band information of the color channel from multiple band information of the color channel included in the information of the input image.
