Hello trend,
Today, we are sharing the definitive guide for Contour Detection in OpenCV. We will also talk about OpenCV Weekly Webinar.
An image is simply an array of numbers (pixel values). To make sense of this array of numbers, we have to extract information from an image so that we can reason at a higher level of abstraction. So, we often pre-process the image using operations like thresholding, or find interesting features like edges. With detected edges, you can do simple shape analysis like finding circles. But if you want to do more interesting shape analysis, you need to contours which are nothing but a chain of connected edges.
In OpenCV, findContours provides a powerful method for finding contours and drawContours help you draw the contours on the image. For beginners, it is not easy to interpret the various inputs to the function. That will why we have written a comprehensive guide that explains how to use findContour in details.

Beginners in OpenCV often do not recognize that it has a rich collection of over 2500+ algorithms. That's a double edged sword. On one hand, we have a large variety of algorithms to choose from. On the other hand, it is easy to get lost if you do not have a background in computer vision.
To help beginners explore the richness of OpenCV and to gain mastery over important algorithms, we created a series of three Official OpenCV Courses. In these courses, we focus heavily on practical problem solving without drowning students in theoretical nitty gritty. If you are interested in getting started, I recommend beginning with Computer Vision I : Introduction. On the other hand, if you are convinced you want a career in Artificial Intelligence, and want to go all in, I recommend Bundle 4 which is a collection of all three courses.
The courses are usually overbooked, and so we have a waitlist. We always give priority to people on the waitlist and you get a one time chance of getting a 20% discount when the enrollment opens. Click on the button below to instantly join the waitlist.

OPENCV WEEKLY WEBINAR : MODELPLACE.AI
We started OpenCV Weekly Webinar last week, and without much promotion we got 250+ people on the live webinar. You can checkout last week's episode at
This week on OpenCV Weekly Webinar, we will discuss an exciting new product - ModelPlace.ai
Modelplace.ai is a marketplace for AI models. We created it to help companies struggling to integrate AI to their processes, and developers aiming to monetize their models. Time : 9 AM Pacific Time, April 1, 2021
Hosts : Anna Petrovicheva, Grigory Serebryakov and Satya Mallick.

Hope to see you there!
Satya
