Ridge-i has obtained a patent for an image processing technology (shadow removal technology) that removes shadows and the like from satellite images and displays what originally existed.
By using this technology, it is possible to reproduce the colors of areas in satellite images that are difficult to see due to the shadows of buildings, etc., improving visibility and making it easier to confirm important information from images.
Generally, an image contains a lot of noise, which poses a problem in human visual confirmation and image analysis processing.
Shadow removal technology detects shadows in satellite images and converts them to the equivalent of other colors to produce a shadowless image. Currently, Ridge-i takes satellite images and provides them after generating shadow-removed images. In the future, the company plans to consider additional development so that it can be installed on satellite imaging platforms such as Tellus.
