2019; Computer Vision Workshop (Robotics Club)

Introduction

Everyone who hasn’t been living under a rock must’ve heard of ‘Computer Vision’; if not, go check out Wikipedia or Google it out first!

From face and object recognition to image stabilization and image compression, a lot of current technology trends are a part of the field in question, or an application thereof.

Robotics Club, IITG considers this field as important as programming in the current fast-moving technological world. We organized a workshop on basic CV techniques, mainly dealing with image processing methods using the well-known OpenCV library.

Organized by 2nd year students in the team every year, this workshop is meant mainly for the freshman students, giving them a boost and raising their interest in the vast field of Robotics and AI.

This year we went through the following topics along with hands-on session for each one –

1. Image processing, the idea!

2. Images and common types – Grayscale, RGB

3. Color models – RGB, HSV

4. Introduction to OpenCV – image read, show, write; video capture

5. Introduction to OpenCV – drawing and writing functions

6. Geometric transformations – Scaling, translation, rotation

7. Image processing – Filters, blurring, color segmentation, thresholding

8. Image processing – Canny edge detection

9. Introduction to Haar cascades and ML
