为了将图像提供给pytorch网络,我首先需要将其缩小到某个固定大小。首先,我使用PIL.Image.resize()方法,将插值模式设置为BILINEAR。然后我认为,首先将一批图像转换为pytorch张量,然后使用torch.nn.functional.interpolate()函数在图形处理器上一次缩放整个张量会更方便(也可以使用“双线性”插值模式)。这导致了模型精度的降...

看起来scipy.interpolate.RectBivariateSpline可以做到这一点：
NonUniformImage可用于显示具有插值的实际bin边缘: >>>ax = fig.add_subplot(133, title='NonUniformImage: interpolated',...aspect='equal', xlim=xedges[[0,-1]], ylim=yedges[[0,-1]])>>>im = NonUniformImage(ax, interpolation='bilinear')>>>xcenters = (xedges[:-1] + xedges[1:]) ...

Basically, any pair of coordinates between point 1 (pt1) and point 2 (pt2) can be converted to x- and y- pixel integers, so we don't need any interpolation. import numpy as np from PIL import Image import matplotlib.pyplot as plt def euclideanDistance(coord1,coord2): return np.sqrt...
