Izoštri/očisti podvodnu sliku 4+

Ova aplikacija pojašnjava podvodne i podmorske slike.

■Sve u svemu
Boje mogu biti čudne pod vodom.
Slika će imati plavo-zelenu nijansu i neće izgledati jasno.

Ova aplikacija ispravlja tonove boja i koristi algoritme kako bi izgledali jasnije.

■Što ova aplikacija radi interno

Dok se spuštate pod vodu, crvena boja će nestati kao prva stvar zbog koje će slika izgledati više plava i zelena.
Podešavanjem svakog kanala boja, boje se mogu vratiti i učiniti sliku prirodnijom s većim kontrastom. Ovaj algoritam ima za cilj to učiniti automatski.



■Algoritam
1. Izračunajte prosječnu boju za sliku.
2. Pomaknite boje u crveni kanal do minimalne prosječne vrijednosti crvene od 60.
3. Napravite RGB histogram s novom crvenom bojom.
4. Pronađite nisku razinu praga i visoku razinu praga.
5. Normalizirajte niz tako da razina praga bude jednaka 0, a najviši prag jednak 255.

This application clarifies underwater and undersea images.

■Overall
Colors can be strange underwater.
The image will have a blue-green tint and will not look clear.

This application corrects the color tones and uses algorithms to make them appear clearer.

■What this app does internally

As you descent underwater The red color will disappear as the first thing which will make the image appear more blue and green.
By adjusting each color channel, the colors can be restored and make the image appear more natural with higher contrast. This algorithm aims at doing this automatically.



■The algorithm
1. Calculate the average color for image.
2. Hueshift the colors into the red channel until a minimum red average value of 60.
3. Create RGB histogram with new red color.
4. Find low threshold level and high threshold level.
5. Normalize array so threshold level is equal to 0 and threshold high is equal to 255.
