OpenCV C++ Projects with Qt Framework

Repository of OpenCV projects implemented in C++ with the Qt framework. This collection of projects is inspired by the book "OpenCV 2 Computer Vision Application Programming Cookbook" by Robert Laganière. Each project provides practical examples to beter understand computer vision concepts and enhance your skills.

Projects

1. Playing with Images

Explore basic image loading, display, and manipulation using OpenCV.

2. Manipulating the Pixels

Learn pixel-level operations to manipulate image data.

3. Processing Images with Classes

Organize image processing functionality into classes for modularity.

4. Counting Pixels with Histograms

Utilize histograms to analyze and count pixel values in images.

5. Transforming Images with Morphological Operations

Apply morphological operations for image transformations.

6. Filtering the Images

Implement various filters for smoothing and enhancing images.

7. Extracting Lines, Contours, and Components

Identify and extract lines, contours, and connected components.

8. Detecting and Matching Interest Points

Implement algorithms to detect and match interest points in images.

9. Estimating Projective Relations in Images

Explore projective transformations and their applications.

10. Processing Video Sequences

Extend your skills to process video sequences and apply computer vision techniques in real-time.

How to Use

1. Prerequisites:

   • Make sure you have OpenCV and Qt installed on your system.
   • OpenCV version 4.8.0
   • Qt version 5.15.12 MinGW 32-bit
   • To link OpenCV with Qt projects you can check this video YouTube video

2. Clone the Repository:

   git clone https://github.com/sakuragi97/cpp-opencv.git
   cd cpp-opencv

3. Build and Run:

   • Use Qt Creator to build and run the projects.
   • Navigate to the specific project folder.
   • The projects are sepereted as different main windows, you can choose the project based on the main window on the main.cpp

4. Explore and Learn:

   • I used comments sections to split different tasks
   • Delve into the source code, experiment, and modify as you learn.

Note: The main purpose of this repository was to free practice and implement different OpenCV tasks with C++ for my self-learning. Please feel free to use the code, but I can't promise support or free-code-bugs.
