我在图像中有分割轮廓，我想连接它们，假设它们是参数化曲线。我正在考虑一些曲线拟合或曲线追踪- 但我不知道如何实现它。

我有正好 1 px 宽的分割轮廓：

import itertools
import cv2

# Get all pixel directions
directions = list(itertools.product([-1, 0, 1], repeat=2))
directions.remove((0, 0))

# Load image
img = cv2.imread("image.png", cv2.IMREAD_COLOR)
gray = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)

cv2.imshow("Input", img)

# Find contours
_, thresh = cv2.threshold(gray, 25, 255, cv2.THRESH_BINARY)
contours, _ = cv2.findContours(thresh, cv2.RETR_LIST, cv2.CHAIN_APPROX_NONE)

我知道，所有轮廓的终点在哪里：

for cnt in contours:   
    ends = [] 

    # Get ends of contour
    # - first pixel is not always the …
