imread.image.io上的深入学习scipy.misc语法错误

Question

我有一段python代码，用于提取字母并标记包含图像的每个区域。 我在用谷歌colab

我得到以下错误：

NameError回溯（最近一次呼叫上次）

在（） 一,

----->；2 image=imageio.imread（“https://pbs.twimg.com/profile_images/985792111713947648/7YD1ZYpe_400x400.jpg”） 3. 4. 五,

名称错误：未定义名称“imageio”

以下是完整的代码：

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.patches as mpatches
from scipy.misc import imageio.imread,imresize
from skimage.segmentation import clear_border
from skimage.morphology import label
from skimage.measure import regionprops

image = imageio.imread('https://pbs.twimg.com/profile_images/985792111713947648/7YD1ZYpe_400x400.jpg')



#apply threshold in order to make the image binary
bw = image < 120

# remove artifacts connected to image border
cleared = bw.copy()
clear_border(cleared)

# label image regions
label_image = label(cleared,neighbors=8)
borders = np.logical_xor(bw, cleared)
label_image[borders] = -1

print(label_image.max())

fig, ax = plt.subplots(ncols=1, nrows=1, figsize=(6, 6))
ax.imshow(bw, cmap='jet')

Answer 1

您正在使用尚未导入的包中的函数。首先需要在系统中安装imageio（pip install imageio），然后将其包含在代码中（并删除其他imread）。新守则将是：

import imageio
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.patches as mpatches
from skimage.segmentation import clear_border
from skimage.morphology import label

如果你要使用imresize，你需要安装枕头
