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++

Given the function below, what should be the value of the parameter `angle` to rotate the image 60 degrees in the counterclockwise direction?

`rotationMatrix = getRotationMatrix2D(pointRot, angle, 
 scale)` 


Given the function below, what should be the value of the parameter <code>angle</code> to rotate the image 60 degrees in the counterclockwise direction?
<code>rotationMatrix = getRotationMatrix2D(pointRot, angle, scale)</code>

`warpPerspective(warpedImage, img, matrix, Point(w, h));`

`warpPerspective(img, warpedImage, matrix, Point(w, h));`

`warpPerspective(img, warpedImage, matrix, Point(h, w));`

`warpPerspective(img, warpedImage, Point(w, h));`

We have an image read as `img`. What is the correct way to warp the image, represented as `warpedImg`, using the matrix `m`, width `w`, and height `h`?

We have an image read as <code>img</code>. What is the correct way to warp the image, represented as <code>warpedImg</code>, using the matrix <code>m</code>, width <code>w</code>, and height <code>h</code>?

How do we get the dimensions of an image read as `img`?

How do we get the dimensions of an image read as <code>img</code>?
