opencv圖像特征融合-seamlessClone

seamlessClone是一種圖像融合技術，使用此函數可以輕松将一幅圖像中的指定目标複制後粘貼到另一幅圖像中，并自然的融合。

函數說明：

1. src： 輸入8位3通道圖像的貼圖
2. dst： 輸入8位3通道圖像的原圖
3. mask： 輸入8位1或3通道圖像(目标掩碼區域圖像)
4. p： 對象被放置在目标圖像dst中的位置
5. blend： 輸出圖像，與dst具有相同大小和類型
6. flags： 克隆方法可以是cv :: NORMAL_CLONE，cv :: MIXED_CLONE或cv :：MONOCHROME_TRANSFER

克隆方法1：NORMAL_CLONE: 不保留dst 圖像的texture細節。目标區域的梯度隻由源圖像決定。

import cv2
import numpy as np
from math import sqrt
# 原圖
img_back = cv2.imread(r"test.png")
# 貼圖
img_obj = cv2.imread(r"defect_images/def3.png")
# 掩膜，确定貼圖的ROI區域（0表示不需要的區域，255表示需要貼合的區域）
mask = 255*np.ones(img_obj.shape,img_obj.dtype)
# 擷取原圖寬高
width,height,channels = img_back.shape
# 粘貼位置
loaction = (height//2,width//2)
# 進行貼合
normal_clone = cv2.seamlessClone(img_obj,img_back,mask,loaction,cv2.MIXED_CLONE)
# 顯示貼合結果
while (1):
    cv2.imshow('selectROI', normal_clone)
    if cv2.waitKey(1) & 0xFF == 27:  # Esc按下退出
        break

cv2.destroyAllWindows()
