医学图像处理-目标检测之图像格式转换的问题合集1 (python)

 1. 遇到无法将dcm格式转成jpg的错误

报错：AttributeError: module ‘scipy.misc’ has no attribute ‘imsave’

【解决】

删除：import scipy.misc
改成： import imageio

删除：save_image = scipy.misc.imsave(out_path, DATA)
改成：save_image = imageio.imsave(out_path, DATA)

2. dcm转成jpg格式后，图像全黑的问题

当时的代码：

ds = pydicom.read_file(dcm_path)
img = ds.pixel_array  # Extract image information
imageio.imsave(out_path, img)

【解决】

ds = pydicom.read_file(dcm_path)
img = ds.pixel_array  # Extract image information

# Get the number of pixel
lens = img.shape[0] * img.shape[1]

# Get the max and min of pixel
temp = np.reshape(img, (lens,))
max_val = max(temp)
min_val = min(temp)

# Image normalization
img = (img - min_val) / (max_val - min_val)

# Draw the image and save
plt.imshow(img)
imageio.imsave(out_path, img)
