参考链接问题中的解决方案:你可以调整 shift_hue()
函数调整色调,饱和度和值而不仅仅是色调。然后,您应该可以根据需要调整所有这些参数。
Refering to the solution in the linked question: You can adjust the shift_hue()
function to adjust hue, saturation and value instead of just hue. That should then allow you to shift all of these parameters just as you like.
原文:
def shift_hue(arr, hout):
r, g, b, a = np.rollaxis(arr, axis=-1)
h, s, v = rgb_to_hsv(r, g, b)
h = hout
r, g, b = hsv_to_rgb(h, s, v)
arr = np.dstack((r, g, b, a))
return arr
调整版本:
def shift_hsv(arr, delta_h, delta_, delta_v):
r, g, b, a = np.rollaxis(arr, axis=-1)
h, s, v = rgb_to_hsv(r, g, b)
h += delta_h
s += delta_s
v += delta_v
r, g, b = hsv_to_rgb(h, s, v)
arr = np.dstack((r, g, b, a))
return arr
假设您知道原始图像的基色和所需的目标颜色,您可以轻松计算增量:
Assuming you know the base color of your original image and the target color you want, you can easily compute the deltas:
base_h, base_s, base_v = rgb_to_hsv(base_r, base_g, base_b)
target_h, target_s, target_v = rgb_to_hsv(target_r, target_g, target_b)
delta_h, delta_s, delta_v = target_h - base_h, target_s - base_s, target_v - base_v
