QUESTION
I am building a model for face mask detection on Google collab. I'm unable to save the model to my drive. I ran the following code on Google Collab:
...ANSWER
Answered 2021-May-12 at 07:58Change your directory to Google drive and perform model.save()
Add %cd /content/drive/MyDrive/
to change your directory inside drive.
Another option is to give the full path while using model.save()
Like this model.save('content/drive/MyDrive/face_mask_detection_alert_system.h5')

QUESTION
I want to crop an image properly. Lets say my image is called frame
and x
, y
, w
and h
are xmin
, ymin
, xmax
and ymax
, respectively:
ANSWER
Answered 2020-Dec-09 at 12:39I think you got some misunderstanding about how indexing and slicing in numpy works:
For your first line y:y + h
basically means slice from index y to index y + h
. Same goes for the second dimension, there you take the array slice from x to x + w
.
So basically x
and y
correspond to your xmin
and ymin
and you slice to xmax
and ymax
which is the window minimums plus the corresponding height and width; that's why you have y + h
and x + w
in the second part of both dimensions.
As for frame[y:y, x:x]
- this makes no sense at least in python, so you might have mixed up something there. If you slice from the index to the same index, your resulting array will always be empty:
