我有 20 个小图像(我想放在背景图像(13x12)的目标区域中。我已经用圆圈标记了我的目标区域,我有两个像素数组中的圆圈坐标。现在我想要了解如何将我的 20 个小图像随机添加到我的像素阵列中的随机区域,这些像素阵列基本上是目标区域(绘制的圆圈)。
在我的代码中,我只尝试了一张图片,如果有效,我将传递我的 20 张小图片的文件夹。
# Depencies importation
import cv2
import numpy as np
# Saving directory
saving_dir = "../Saved_Images/"
# Read the background image
bgimg = cv2.imread("../Images/background.jpg")
# Resizing the bacground image
bgimg_resized = cv2.resize(bgimg, (2050,2050))
# Read the image that will be put in the background image (exemple of 1)
# I'm just trying with one, if it works, I'll pass the folder of the 20
small_img = cv2.imread("../Images/small.jpg")
# Convert the resized background image to gray
bgimg_gray = cv2.cvtColor(bgimg, cv2.COLOR_BGR2GRAY)
# Convert the grayscale image to a binary image
ret, thresh = cv2.threshold(bgimg_gray,127,255,0)
# Determine the moments of the binary image
M = cv2.moments(thresh)
# calculate x,y coordinate of center
cX = int(M["m10"] / M["m00"])
cY = int(M["m01"] / M["m00"])
# Drawing the circle in the background image
circle = cv2.circle(bgimg, (cX, cY), 930, (0,0,255), 9)
print(circle) # This returns None
# Getting the coordinates of the circle
combined = bgimg[:,:,0] + bgimg[:,:,1] + bgimg[:,:,2]
rows, cols = np.where(combined >= 0)
# I have those pixels in rows and cols, but I don't know
# How to randomly put my small image in those pixel
# Saving the new image
cv2.imwrite(saving_dir+"bgimg"+".jpg", bgimg)
cv2.namedWindow('image', cv2.WINDOW_NORMAL)
cv2.resizeWindow("Test", 1000, 1200)
# Showing the images
cv2.imshow("image", bgimg)
# Waiting for any key to stop the program execution
cv2.waitKey(0)
在预期的结果中,小图像必须随机放置在背景图像中
