Question

我有點卡在這里，找不到最佳性能有效的算法來從 RGB 列表中找到與目標值最接近的 5 個值。

顏色列表：

Target color:  [202, 200, 198]

the expected valaue:
[[#,#,#], [#,#,#], [#,#,#], [#,#,#], [#,#,#]]

我正在使用這組顏色列表來查找具有相似 colors 的圖像。 可能存在重復值，並且應考慮忽略確切值，因為這些值是從一組可以是完全相同的照片的圖像中提取的。

Answer 1

使用歐式距離：

import math

def distance(a, b):
    return math.hypot(*(v2 - v1 for v1, v2 in zip(a, b)))

target = [202, 200, 198]

closest = sorted(colors, key=lambda x: distance(target, x))
print(closest[:5])

Answer 2

如果沒有關於什么是“最接近”的 RGB 的詳細定義，我認為這個助手可能會為您提供一些想法？

導入數學

def distance(c1, c2):
    r1,g1,b1 = c1
    r2,g2,b2 = c2
    return math.sqrt((r1 - r2)**2 + (g1 - g2) ** 2 + (b1 - b2) **2)

然后你可以通過 color_list 來檢查和匹配。
