[ Python OpenCV ] 이미지 테두리 만들기

[ Python OpenCV ] 이미지 테두리 만들기 - cv.copyMakeBorder

1. Opencv 연결 및 이미지 불러오기

import cv2 as cv

# 이미지 경로
image = cv.imread('/home/heojungwook/VSCode
                                /cat.jpeg')

# 이미지 쇼 (Form Title Name)
cv.imshow('ORIGINAL', image)

2. 테두리 만들기 copyMakeBorder

def copyMakeBorder(src, top, bottom, left, right,

borderType, dst=None, value=None, /)

src - 이미지

top - 위쪽

bottom - 아래쪽

left - 왼쪽

right - 오른쪽

borderType - 테두리 종류

3. 기본 테두리 BORDER_DEFAULT

import cv2 as cv

# 이미지 경로
image = cv.imread('/home/heojungwook/VSCode
                                    /cat.jpeg')

nTop = 20
nBottom = 20
nLeft = 20
nRight = 20
DEFAULT = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_DEFAULT)

cv.imshow('DEFAULT', DEFAULT)

4. 끊임없는 테두리 BORDER_CONSTANT

CONSTANT = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_CONSTANT)
cv.imshow('CONSTANT', CONSTANT)

5. 외딴 테두리 BORDER_ISOLATED

ISOLATED = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_ISOLATED)
cv.imshow('ISOLATED', ISOLATED)

6. 반사 테두리 BORDER_REFLECT

REFLECT = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_REFLECT)
cv.imshow('REFLECT', REFLECT)

7. 반사 101 테두리 BORDER_REFLECT101

REFLECT101 = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_REFLECT101)
cv.imshow('REFLECT101', REFLECT101)

8. 반사 _101 테두리 BORDER_REFLECT_101

REFLECT_101 = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_REFLECT_101)
cv.imshow('REFLECT_101', REFLECT_101)

9. 포장 테두리 BORDER_WRAP

WRAP = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_WRAP)
cv.imshow('WRAP', WRAP)

10. 전체 소스

import cv2 as cv

# 이미지 경로
image = cv.imread('/home/heojungwook/VSCode
                                /cat.jpeg')

# 이미지 쇼 (Form Title Name)
cv.imshow('ORIGINAL', image)
nTop = 20
nBottom = 20
nLeft = 20
nRight = 20
DEFAULT = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_DEFAULT)

cv.imshow('DEFAULT', DEFAULT)
CONSTANT = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_CONSTANT)

cv.imshow('CONSTANT', CONSTANT)
ISOLATED = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_ISOLATED)

cv.imshow('ISOLATED', ISOLATED)
REFLECT = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_REFLECT)

cv.imshow('REFLECT', REFLECT)
REFLECT101 = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_REFLECT101)

cv.imshow('REFLECT101', REFLECT101)
REFLECT_101 = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_REFLECT_101)

cv.imshow('REFLECT_101', REFLECT_101)
REPLICATE = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_REPLICATE)

cv.imshow('REPLICATE', REPLICATE)
WRAP = cv.copyMakeBorder(image, nTop, nBottom,
    nLeft, nRight, borderType=cv.BORDER_WRAP)
cv.imshow('WRAP', WRAP)
