python图像处理_色彩转换

1.RGB图像染色

from skimage import data import matplotlib.pyplot as plt from skimage.color import rgb_from_bpx,bpx_from_rgb,separate_stains,combine_stains ihc=data.immunohistochemistry() ihc_hdx=separate_stains(ihc,bpx_from_rgb) ihc_rgb=combine_stains(ihc_hdx,rgb_from_bpx) plt.subplot(131) plt.imshow(ihc) plt.subplot(132) plt.imshow(ihc_hdx) plt.subplot(133) plt.imshow(ihc_rgb) plt.show()

1.颜色空间转换

from skimage import data
from skimage.color import convert_colorspace
import matplotlib.pyplot as plt
img=data.astronaut()
img_hsv=convert_colorspace(img,'RGB','HSV')
plt.subplot(121)
plt.imshow(img)
plt.subplot(122)
plt.imshow(img_hsv)

plt.show()

3、彩色灰度图像转换

from skimage import data from skimage.color import grey2rgb,rgb2gray import matplotlib.pyplot as plt img=data.chelsea() im_gray=rgb2gray(img) plt.subplot(121) plt.imshow(img) plt.title('rigial image') plt.subplot(122) plt.imshow(im_gray,plt.cm.gray) plt.title('grey image') plt.show()
