Writing image in in directory in opensv code

Question

I am trying to write image in my opencv code, which is fine if i write without directory. But when I am trying to write in directory, it run but does not write in directory.

for i in xrange(3):
    path = 'resultImages/result'
    print os.path.join(path,str(i),'.png')
    cv.imwrite(os.path.join(path,str(i),'.png'),images[i*3+2])

Anything wrong here?

I reffered OpenCV - Saving images to a particular folder of choice but no help.

if resultImages is inside the directory where the images are automatically saved, try putting '/' in front of resultImages ('/resultImages/result') — murksiuke, Oct 23 '18 at 11:02
@Silencer: dir path is there, and also tried with `('/resultImages/result')` but no luck — user2129623, Oct 23 '18 at 11:07
try using `os.path.exists(path)` to check if the path exists... also `os.path.join(path,str(i),'.png')` this should give something like `resultImages/result/0/.png` and it should be something like `os.path.join(path,str(i)+'.png')` — api55, Oct 23 '18 at 11:29

The problem is due to the fact you are using ".png" as a sub directory inside the os.path.join() function

Try changing it to this:

for i in xrange(3):
    path = 'resultImages/result'
    print os.path.join(path,str(i) + '.png')
    cv.imwrite(os.path.join(path,str(i) +'.png'),images[i*3+2])

I hope it helped
