How to use HSV color format instead of LAB?

[rakeshwar07]

#Change HSV, making it more natural,optional

im[x, y] = color.lab2rgb(val.reshape(len(x), 1, 3)).reshape(len(x), 3) * 255

hsv_val = cv2.cvtColor(im,cv2.COLOR_BGR2HSV)

hsv_val2=hsv_val[x,y]

L3,A3,B3=mean(hsv_val2[:, 0]), mean(hsv_val2[:, 1]),mean(hsv_val2[:, 2])

hsv_val2[:,0]-=0

hsv_val2[:,1]-=0

hsv_val2[:,2]+=0

I changed the above code like "# #Change RGB color

val = color.rgb2lab((im[x, y] / 255.).reshape(len(x), 1, 3)).reshape(len(x), 3)

L, A, B = mean(val[:, 0]), mean(val[:, 1]), mean(val[:, 2])

L1, A1, B1 = color.rgb2lab(np.array((r / 255., g / 255., b / 255.)).reshape(1, 1, 3)).reshape(3, )

ll, aa, bb = L1 - L, A1 - A, B1 - B

val[:, 0] +=ll*inten

val[:, 1] +=aa*inten

val[:, 2] += bb*inten " but the result was very bad.

Could you pls show how to use the hsv instead of lab?
