PASANDO A HSV

import skimage

from skimage.filters import unsharp_mask

img = cv2.imread('B.jpg')

HSV = cv2.cvtColor(img,cv2.COLOR_RGB2HSV)

V = HSV[:,:,2]

H = HSV[:,:,0]

S = HSV[:,:,1]

resultV = unsharp_mask (V, radius =2, amount=5)

resultV = np.uint8(255*resultV)

img2 = np.dstack((H,S,resultV))

RGB = cv2.cvtColor(img2,cv2.COLOR_HSV2RGB)

plt.figure(figsize=(12,12))

plt.imshow(RGB[...,::-1])
