Welcome to this new lecture of the course,
and this is quite special, I happen to
be on camera because in this lecture,
what you're going to build is a program
that detects object, moving objects in
front of a computer webcam, and then
what it does, it records the time that
the object entered the webcam. So the
video frame and the time when the
object exited the video frame.
So now, there's moving object
[No audio]
in the frame, and if I go wait, you see that
and there is no green rectangle now in the video
and now I show up again, move out
again, and so on. So we're going to
build this application from scratch
using Python, and yeah, we have a lot of
things to learn, such as image
processing and video processing, as
well, and so on, and lastly, what we do
then if you press Q for quit, and what you
get is a graph, and as I said the graph will
show the times where the object enter
the frame. So we're dealing with an
interactive graph here, and yeah, these
are the times when the object entered
the webcam, like this one or this one
here, and here it lasts longer and so on. This
can be a great application if you want
to detect objects. You get through, you
can put this application, this Python
program in a Raspberry Pi Server, for
instance, which is a small server and
you can put it somewhere and maybe want
to detect animals. You may want to know
when this animal is entering the frame
and when it is exiting, or with people as
well, if there is the case. And so yeah,
this is a program and I hope you
enjoyed. We have quite a lot of code to
write, so let's get started and I'll
talk to you in the next lecture.
