python - 不能在不改变颜色的情况下覆盖面膜？

Question

从下面的图像中，我使用以下代码在蒙版下面创建了:

 hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
 mask = cv2.inRange(hsv, lower_color, upper_color)
 res = cv2.bitwise_and(img,img, mask= mask)

面具:

我想覆盖看起来像这样的资源:

我使用下面的代码来覆盖它。

bgra = cv2.addWeighted(bgra, 1, res, 1, 0)

循环改变原始图像的颜色

for i in tqdm((range(rang)), ascii=True, desc = 'Loops'):
        hmod += speed
        alpha = img[:, :, 3]

        bgr = img[:, :, 0:3]

        hsv = cv2.cvtColor(bgr, cv2.COLOR_BGR2HSV)

        h, s, v = cv2.split(hsv)

        hnew = np.mod(h + hmod, 180).astype(np.uint8)

        hsv_new = cv2.merge([hnew, s, v])

        bgr_new = cv2.cvtColor(hsv_new, cv2.COLOR_HSV2BGR)

        bgra = cv2.cvtColor(bgr_new, cv2.COLOR_BGR2BGRA)
        bgra[:, :, 3] = alpha
        if maskPresent[-1]:
            bgra = cv2.addWeighted(bgra, 1, res, 1, 0)
        if i == 0:
            chromas = bgra
        else:
            try:
                chromas = cv2.vconcat([bgra, chromas])
            except MemoryError:
                raise MemoryError('Out of memory(Try using an image with a lesser resolution or use  a higher speed)')

但这即使在res变量保持不变的情况下，也可以在连接图像时更改蒙版的颜色。有谁知道解决方法？

Answer 1

chromares = cv2.bitwise_and(bgra, bgra, mask= mask)
bgra -= chromares
bgra += originalres #what was res```
