This is more like a query.I am processing some images using opencv and the images are in AdobeRBG space , opencv is able to convert it to RGB .But thats deteriorating the image color.the later one look dull. Is there a way I can handle this case.

You should know the difference between sRGB and Adobe RGB.Sorry, opencv and pillow can not complete this task very well.You should try to process the image with imagemagick first.Like this:

from PIL import Image, ImageCMS
import numpy as np
srgb = ImageCms.createProfile('sRGB')
def get_adobe(img):
    output = BytesIO()   
    output.write(img.info.get('icc_profile'))
    output.seek(0)
    adobe = ImageCms.getOpenProfile(output)     
    return adobe


def convert_to_srgb(image):
    if image.info.get('icc_profile', ''):
        adobe = get_adobe(image)
        image = ImageCms.profileToProfile(image, adobe, srgb)
    return image
