Webbskimage library）。然后我认为可以做的是，将边缘内的像素变白，将边缘外的像素变黑。之后，可以对原始图像进行遮罩，仅获取人物的图片. 然而，使用canny边缘检测器很难获得闭合边界。使用Sobel过滤器的结果并没有那么糟糕，但我不知道如何从那里开始. 编辑： Webbfrom skimage import measure import matplotlib.pyplot as plt contours = measure.find_contours (mask, 0.5) plt.imshow (mask) for n, contour in enumerate …
The active contour model is a method to fit open or closed splines to lines or edges in an image [ 1]. It works by minimising an energy that is in part defined by the image and part by the spline’s shape: length and smoothness. The minimization is done implicitly in the shape energy and explicitly in the image energy. WebbThis is a version of the Geodesic Active Contours (GAC) algorithm that uses: morphological operators instead of solving partial differential equations (PDEs) for the evolution of the …

WebbOther methods of blurring. The Gaussian blur is a way to apply a low-pass filter in skimage. It is often used to remove Gaussian (i. e., random) noise from the image. For other kinds of noise, e.g. “salt and pepper”, a median filter is typically used. See the skimage.filters documentation for a list of available filters.
