En este desafío, debe encontrar un píxel específico dentro de una fotografía (tomada con una cámara real).
Se le pasa una tupla (R, G, B) y una imagen, y necesita devolver un punto (x, y) dentro de la imagen que coincida con el color RGB dado . La imagen puede tener múltiples puntos que coinciden con el color; solo necesitas encontrar 1.
El desafío es que debes hacerlo mientras lees la menor cantidad de píxeles posible . Su puntaje será el número total de píxeles leídos en todos los casos de prueba.
Si lo desea, puede leer la imagen completa en una matriz de valores RGB, siempre que no realice ningún procesamiento en los píxeles. Permito esto únicamente para fines de eficiencia. Por ejemplo, en Python, list(Image.open("image_name+".jpg").convert("RGB").getdata())
está bien.
No se permiten ubicaciones de codificación fija. Su algoritmo debería funcionar bien para algo más que los casos de prueba enumerados a continuación. No está permitido guardar datos entre casos de prueba. Elegí valores RGB que aparecen con poca frecuencia ( <10
) en la imagen (en caso de que eso marque la diferencia en su algoritmo). Si está utilizando aleatoriedad en su algoritmo, establezca una semilla para que su puntaje sea constante.
Las imágenes se pueden encontrar en Github
