matlab - opencv-python image processing code-debugging -


i have written code in ocv-python image processing(detection of veins in eye), not working, can help?

import os,sys import numpy np import scipy import cv2 import pil import image import imagechops  i=cv2.imread('eye.jpg',0); cv2.imshow(i); j= cv2.medianblur(i, 3); clahe = cv2.createclahe(cliplimit=2.0, tilegridsize=(8,8)); k= clahe.apply(j); kernel = np.ones((5,5),np.uint8); closing = cv2.morphologyex(k, cv2.morph_close, kernel); h, w = i.shape[:2]; seed_pt = none; mask = np.zeros((h+2, w+2), np.uint8); l=cv2.floodfill(k, mask, seed_pt, (255, 255, 255)); o=imagechops.difference(closing,l); (thresh, im_bw) = cv2.threshold(o, 128, 255, cv2.thresh_binary | cv2.thresh_otsu); cv2.imshow(im_bw);

'

particularly having problem reading .jpg file(it reads .png file), imshow() function not working, , errors being shown imagechops , otsu threshold function.

the matlab code above code is(it working perfectly):

t=('http://www.ohiolionseyeresearch.com/core/files/uploads/2014/03/1217.png');  i=imread(t);  figure, imshow(i) q=rgb2hsv(i); t=rgb2gray(i); figure, imshow(t) k=medfilt2(t); figure, imshow(k)  u=adapthisteq(k);  se=strel('disk',10);  c=imclose(u,se);  figure, imshow(c)  d=imfill(u,'holes');  figure, imshow(d)  z=imabsdiff(c,d);  figure, imshow(z)  level=graythresh(z);  bw=im2bw(z,level);  imshow(bw)

angularjs - ADAL JS Angular- WebAPI add a new role claim to the token -

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.
