OpenCV

OpenCV-GUI

OpenCV is extensively used in the business world for various applications, including facial recognition, object detection, and image and video manipulation. 

In this course, you'll learn the basics of OpenCV—an open-source machine learning library. You'll begin with an overview of the OpenCV library before moving on to practical applications like viewing images, videos, and webcam input. Next, you'll learn how to edit images with tools like decolorizing, cropping, resizing, and captioning. You'll dive into machine learning functions like edge detection, contour detection, corner detection, and face detection. Finally, you'll work on practical projects like document scanners and object trackers. 

By the end of this course, you’ll have a solid understanding of OpenCV and machine learning with C++. You'll be able to create functional applications using computer vision principles, preparing you for real-world projects. Taking this course will allow you to take your programming skills to the next level.

Learning OpenCV from Scratch with C++

We want to read an image, `image.jpg`, into a `Mat` class object, `img`. What is the right way to accomplish that?

We want to read an image, <code>image.jpg</code>, into a <code>Mat</code> class object, <code>img</code>. What is the right way to accomplish that?

```
while (true) 
{
   capture.read(img);
}
```

```
while (false) 
{
   take.read(image);
}
```

```
while (true) 
{
   take.read(image);
}
```

```
while (true) 
{
   take.imread(image);
}
```

We're given the following code:
```cpp
string videoPath = "vid.mp4";
VideoCapture take(videoPath);
Mat image;
```
What's the correct way to read the frames of the video?


We’re given the following code:
<pre><code class="language-cpp">string videoPath = &quot;vid.mp4&quot;;
VideoCapture take(videoPath);
Mat image;
</code></pre>
What’s the correct way to read the frames of the video?

Suppose we want to read and display the feed from our webcam using the following code:
```cpp
....
VideoCapture capture(x);
....
waitKey(y);
```
What should be the value of `x` and `y`?

Suppose we want to read and display the feed from our webcam using the following code:
<pre><code class="language-cpp">....
VideoCapture capture(x);
....
waitKey(y);
</code></pre>
What should be the value of <code>x</code> and <code>y</code>?
