如何使用 skimage 和 numpy 显示和保存 output 图像？

Question

def show_image_in_region(region):
    minr, minc, maxr, maxc = region.bbox
    plt.imshow(binary_imag[minr:maxr,minc:maxc])

for i in range(0,5):
    show_image_in_region(image_blocks[i])

I have multiple output images which I want to save and display using skimage.

You can use the skimage.io.imsave function to save. It looks like the images will already plot, so can I suggest editing your function to return the region of interest in the image:

from skimage.io import imsave

def show_image_in_region(region):
    minr, minc, maxr, maxc = region.bbox
    plt.imshow(binary_imag[minr:maxr,minc:maxc])
    return binary_imag[minr:maxr,minc:maxc]

and then in your loop:

for i in range(0,5):
    im = show_image_in_region(image_blocks[i])
    imsave('image{}.png'.format(i), im)

which will save a.png file called "image0.png" and so on. Other image files can also be saved using the imsave function.
