Dans ce défi, vous devez trouver un pixel spécifique dans une photographie (prise avec un vrai appareil photo).
Vous passez un tuple (R, G, B) et une image, et vous devez renvoyer un point (x, y) dans l'image qui correspond à la couleur RVB donnée . L'image peut avoir plusieurs points qui correspondent à la couleur; il vous suffit d'en trouver 1.
Le défi est que vous devez le faire en lisant le moins de pixels possible . Votre score sera le nombre total de pixels lus dans tous les cas de test.
Si vous le souhaitez, vous pouvez lire l'image entière dans un tableau de valeurs RVB, tant que vous n'effectuez aucun traitement sur les pixels. J'autorise cela uniquement à des fins d'efficacité. Par exemple, en Python, list(Image.open("image_name+".jpg").convert("RGB").getdata())
c'est ok.
Les emplacements de codage en dur ne sont pas autorisés. Votre algorithme devrait bien fonctionner pour plus que les cas de test répertoriés ci-dessous. Vous n'êtes pas autorisé à enregistrer des données entre les scénarios de test. J'ai choisi des valeurs RVB qui apparaissent rarement ( <10
) dans l'image (au cas où cela ferait une différence pour votre algorithme). Si vous utilisez l'aléatoire dans votre algorithme, veuillez définir une valeur de départ, afin que votre score soit constant.
Les images peuvent être trouvées sur Github
