Images not getting saved in open cv write function

Question

I'm trying to process images and try them to save them. I am able to process it but image are not getting saved in folder

code - Taken from github

import cv2, glob, numpy

def scaleRadius(img,scale):
    x=img[int(img.shape[0]/2),:,:].sum(1)
    r=(x>x.mean()/10).sum()/2
    s=scale*1.0/r
    return cv2.resize(img,(0,0),fx=s,fy=s)

scale =512
for f in (glob.glob("pdr/*.jpeg")):

    a=cv2.imread(f)
    a=scaleRadius(a,scale)
    b=numpy.zeros(a.shape)
    cv2.circle(b,(int(a.shape[1]/2),int(a.shape[0]/2)),int(scale*0.9),(1,1,1),-1,8,0)
    aa=cv2.addWeighted(a,4,cv2.GaussianBlur(a,(0,0),scale/30),-4,128)*b+128*(1-b)
    cv2.imwrite(str(scale)+"_"+f,aa)

Code executes well but it output does not get saved

You ought to pass a proper path inside cv2.imwrite() in order to save the images. The code on github was posted to guide others using it. That does not mean you blindly copy it and expect it to work wonders. — Jeru Luke

cv2.imwrite() doesn't create the directory for you, make sure you've created directory 512_pdr before running the script.
