使用Python和OpenCV对虹膜照片进行圆拟合可以通过以下步骤完成:
import cv2
import numpy as np
image = cv2.imread("iris.jpg")
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
blurred = cv2.GaussianBlur(gray, (11, 11), 0)
edges = cv2.Canny(blurred, 30, 150)
circles = cv2.HoughCircles(edges, cv2.HOUGH_GRADIENT, dp=1, minDist=100,
param1=50, param2=30, minRadius=20, maxRadius=80)
if circles is not None:
circles = np.round(circles[0, :]).astype("int")
for (x, y, r) in circles:
cv2.circle(image, (x, y), r, (0, 255, 0), 4)
cv2.imshow("Detected Iris", image)
cv2.waitKey(0)
cv2.destroyAllWindows()
cv2.imwrite("output.jpg", image)
这样,我们就可以使用Python和OpenCV对虹膜照片进行圆拟合。关于云计算和IT互联网领域的名词词汇,可以参考腾讯云的产品文档和知识库来了解更多。
