[Python 으로 영상처리 (1)] cv2.seamlessClone() 영상의 조화로움!!

💗 NORMAL & MIXED

import cv2
import numpy as np

# 행렬 (색 정보 b g r)
logo = cv2.imread('images/logo.png')
lena = cv2.imread('images/lena.jpg')

mask = np.full_like(logo, 255)
height, width = lena.shape[:2]
center = (width//2, height//2)

# 소스 이미지, destination, 복제 주변 mask, center 이미지, flag
normal = cv2.seamlessClone(logo, lena, mask, center, cv2.NORMAL_CLONE)      # 블러처리
mixed = cv2.seamlessClone(logo, lena, mask, center, cv2.MIXED_CLONE)        # 조화롭게

cv2.imshow('normal', normal)
cv2.imshow('mixed', mixed)
cv2.waitKey(0)
cv2.destroyAllWindows()

 

💗 NORMAL & POLY (특정 엣지 도려내기..)

import cv2
import numpy as np 

# Read images
src = cv2.imread("images/airplane2.jpg")
dst = cv2.imread("images/red_sky.jpg")

# Create a rough mask around the airplane.
src_mask = np.zeros(src.shape, src.dtype)
# 주변 도려내기...
poly = np.array([ (0,40), (150,60), (203,56), (200,100), (88,103), (1,75) ], np.int32)
# poly = np.array([ [4,80], [30,54], [151,63], [254,37], [298,90], [272,134], [43,122] ], np.int32)
cv2.fillPoly(src_mask, [poly], (255, 255, 255))

# This is where the CENTER of the airplane will be placed
center = (600,150)

# Clone seamlessly.
output = cv2.seamlessClone(src, dst, src_mask, center, cv2.NORMAL_CLONE)

# Save result
cv2.imshow('Output', output)
cv2.waitKey(0)
cv2.destroyAllWindows()

(우) 밑에꺼 poly 로 작용하면 머리부분이 지워짐

 

💗 NORMAL & POLY

import cv2
import numpy as np 

src = cv2.imread("images/airplane1.jpg")

output = cv2.seamlessClone(src, dst, src_mask, center, cv2.NORMAL_CLONE)

cv2.imshow('Output', output)

(우) 밑에 poly 실행하면 비행기가 사라지네용
