問題描述
我有一組不同尺寸的圖片(45,50,3), (69,34,3), (34,98,3).我想為這些圖像添加填充，如下所示:
l have a set of images of different sizes (45,50,3), (69,34,3), (34,98,3). l want to add padding to these images as follows:
取整張圖片的最大寬度和長度，然后把圖片放在那個尺寸
Take the max width and length of the whole images then put the image in that size
import os
import glob
import cv2
input_path="/home/images"
os.chdir(indput_path)
images=glob.glob("*.png")
Length=[]
Width=[]
for img in images:
img=cv2.imread(img)
width,length=img.shape[0:2]
Length.append(length)
Width.append(width)
W=max(Width)
L=max(Length)
如何在 opencv 中添加填充以使所有圖像具有相同的大小?在示例中 l 給出的圖像將得到 (69,98,3)
How can l add padding in opencv so that all the images will have the same size? In the example l gave the images will get the shape of (69,98,3)
推薦答案
你可以使用:
image = cv2.copyMakeBorder(src, top, bottom, left, right, borderType)
src 是你的源圖片，top、bottom、left、right 是圖像周圍的填充.
Where src is your source image and top, bottom, left, right are the padding around the image.
您可以在 while 循環中使用 max(sizes) - 圖像的大小值來為每個圖像添加填充.邊框類型可以是以下之一:
You can use max(sizes) - size value of the image in a while loop to add the padding to each image. The bordertype can be one of these:
cv2.BORDER_CONSTANTcv2.BORDER_REFLECTcv2.BORDER_REFLECT_101cv2.BORDER_DEFAULTcv2.BORDER_REPLICATEcv2.BORDER_WRAP
