Image Analysis Toolbox: Have you ever wondered how he sees an animal? How are the images we see around us in the eyes of an animal? In case you are concerned, you can discover it using your camera and your computer.
Scientists from University of Exeter developed a multispectral image calibration and analysis application (Multispectral Image Calibration and Analysis Toolbox ή απλά Image Analysis Toolbox), η οποία θα σας επιτρέψει να δείτε τα χρώματα που βλέπουν τα ζώα σε φωτογραφίες σας.
The program it is distributed for free by the university so if you are interested you can download it.
To use it, you have to select the animal from a long list. Based on this selection of yours, the software will provide you with tips to set up your camera.
Once you have the photos you can upload them to your computer and the program will run the automatic calibration, which separates the colors into different layers.
Eventually it will give you a picture of the colors that the animal you have chosen.
This means that if you choose a non-primate mammal, for example, the red spectrum will be absent - man and Old World monkeys are the only mammals capable of seeing blue, yellow and red, i.e. all the primary colors.
If the animal you chose was a bird, reptile, amphibian or insect, however, the colors may be based on a combination of four or more basic colors.
They may also include colors from the ultraviolet spectrum, which we can not see without dedicated full-spectrum cameras.
If all of these seem very complex to you, researchers are simple because they have already used the application to very innovative ideas. The software, for example, has already been used to monitor the color of the woman's face during the ovulation cycle (by revealing colors that the human eye can not see, to study the color change in crabs, and to understand how birds use the camouflage to protect their eggs.
