OpenCV Python Tutorial For Beginners 21 – Image Pyramids with Python and OpenCV

FavoriteLoadingAdd to favorites

In this video on OpenCV Python Tutorial For Beginners, I am going to show How to use Image Pyramids with Python and OpenCV.
There are two kinds of Image Pyramids. 1) Gaussian Pyramid and 2) Laplacian Pyramids
Gaussian pyramids use cv.pyrDown() and cv.pyrUp() functions.

Gist of code I used in this video (OpenCV: Image Pyramids Tutorial ) –

OpenCV is an image processing library created by Intel and later supported by Willow Garage and now maintained by Itseez. opencv is available on Mac, Windows, Linux. Works in C, C++, and Python.
it is Open Source and free. opencv is easy to use and install.

Starting with an overview of what the course will be covering, we move on to discussing morphological operations and practically learn how they work on images. We will then learn contrast enhancement using equalization and contrast limiting. Finally we will learn 3 methods to subtract the background from the video and implement them using OpenCV.

At the end of this course, you will have a firm grasp of Computer Vision techniques using OpenCV libraries. This course will be your gateway to the world of data science.

Feel the real power of Python and programming! The course offers you a unique approach of learning how to code by solving real world problems.

    Hi, I've been following this playlist, and this is the first tutorial I had a problem with.

    On the line "laplacian = cv2.subtract(gp[i-1], gaussian_extended)
    " I get an error that reads:

    Traceback (most recent call last):

    File "[File Path]", line 20, in <module>
    [code mentioned earlier]

    cv2.error: OpenCV(4.1.1) C:projectsopencv-pythonopencvmodulescoresrcarithm.cpp:663: error: (-209:Sizes of input arguments do not match) The operation is neither 'array op array' (where arrays have the same size and the same number of channels), nor 'array op scalar', nor 'scalar op array' in function 'cv::arithm_op'

    What should I do to fix it? It's some sort of problem with cv2.subtract, because I get good results both for gp[i-1] and gaussian_extended. With the code from your website, I get the same error.

    Thank you very much to anyone who knows what to do.
