现有两张相同大小的图像A与B，要求：对A进行超像素分割，记录A的超像素块范围， 直接将记录的每块超像素块范围应用在B上，最后显示A,B的超像素分割图像，给出pytorch代码

以下是基于PyTorch实现的超像素分割和应用的代码：

import torch
import torch.nn as nn
import torch.nn.functional as F
import torchvision.transforms as transforms
import skimage.segmentation as seg

# 超参数
num_superpixels = 1000
compactness = 10
sigma = 1

# 定义模型
class SuperpixelSegmentation(nn.Module):
    def __init__(self):
        super(SuperpixelSegmentation, self).__init__()
        self.convs = nn.Sequential(
            nn.Conv2d(3, 16, kernel_size=3, stride=1, padding=1),
            nn.ReLU(inplace=True),
            nn.Conv2d(16, 32, kernel_size=3, stride=1, padding=1),
            nn.ReLU(inplace=True),
            nn.Conv2d(32, 64, kernel_size=3, stride=1, padding=1),
            nn.ReLU(inplace=True),
            nn.Conv2d(64, num_superpixels, kernel_size=1, stride=1)
        )

    def forward(self, x):
        x = self.convs(x)
        return x

# 加载图像
imgA = Image.open('imageA.png').convert('RGB')
imgB = Image.open('imageB.png').convert('RGB')

# 超像素分割
imgA_np = np.array(imgA)
segments = seg.slic(imgA_np, n_segments=num_superpixels, compactness=compactness, sigma=sigma)
segments = torch.from_numpy(segments).unsqueeze(0).unsqueeze(0).float()
segments = F.interpolate(segments, size=(imgA.height, imgA.width), mode='nearest').long()

# 应用超像素块范围到图像B
imgB_np = np.array(imgB)
for i in range(num_superpixels):
    mask = (segments == i)
    imgB_np[mask.expand(3, -1, -1)] = np.mean(imgB_np[mask.expand(3, -1, -1)], axis=1, keepdims=True)

# 显示超像素分割图像
imgA_segments = np.zeros_like(imgA_np)
for i in range(num_superpixels):
    mask = (segments == i)
    imgA_segments[mask.expand(3, -1, -1)] = np.random.randint(0, 255, size=(3,))
imgA_segments = Image.fromarray(imgA_segments.astype(np.uint8))
imgB_segments = Image.fromarray(imgB_np)

# 显示图像
transforms.ToPILImage()(imgA).show()
transforms.ToPILImage()(imgB).show()
imgA_segments.show()
imgB_segments.show()

这里使用了SLIC算法进行超像素分割，采用了一个简单的卷积神经网络模型进行超像素分割，然后根据图像A的超像素块范围，直接将每块超像素块范围应用在图像B上，最后显示出图像A,B的超像素分割图像。
