Answer 1

Use eroded (or dilated black objects) second image as mask for first image.

import cv2
import numpy as np
#images need equal size
original=cv2.imread('RdfpD.png')
mask = cv2.imread('zxLX4.png', cv2.IMREAD_GRAYSCALE)
se=cv2.getStructuringElement(cv2.MORPH_ELLIPSE,(3,5))
ret,thresh = cv2.threshold(mask,60,255,cv2.THRESH_BINARY_INV)

dilate = cv2.dilate(thresh,se,iterations = 1)
dilate=cv2.bitwise_not(dilate)
dilate=cv2.cvtColor(dilate, cv2.COLOR_GRAY2BGR)
out=cv2.max(dilate, original)
cv2.imwrite('out_5.png', out)
