Feature Matching (Brute-Force) – OpenCV 3.4 with python 3 Tutorial 26
In this tutorial we will talk about Feature Matching with OpenCV. In my example I used the same book cover but in different lighting conditions, position and perspective. For a normal comparison they could be different but two simple steps we can compare the main characteristics: Orb detector method Passing the image to the ORB […]
Feature detection (SIFT, SURF, ORB) – OpenCV 3.4 with python 3 Tutorial 25
We’re going to learn in this tutorial how to find features on an image.We have thre different algorythms that we can use: Each one of them as pros and cons, it depends on the type of images some algorithm will detect more features than another.SIFT and SURF are patented so not free for commercial use, […]
Lines detection with Hough Transform – OpenCV 3.4 with python 3 Tutorial 21
We’re going to learn in this tutorial how to detect the lines of the road in a live video using Opencv with Python. Before going into the lines road detection, we need to understand using opencv what is a line and what isn’t a line. Hough lines transform: The Houg lines transform is an algorythm […]
Find and Draw Contours – OpenCV 3.4 with python 3 Tutorial 19
We’re going to see in this tutorial how to find and draw the contours.Contours are simply the boundaries of an object. We first import the libraries and we load the Camera. import cv2 import numpy as np cap = cv2.VideoCapture(0) We start the while loop to work with a video, so we loop trough […]
Edge detection – OpenCV 3.4 with python 3 Tutorial 18
What you will learn about edge detection The opencv edge detection is the image processing procedure, that allows you to structure the image pixels in order to show and highlight their edges. With opencv this operation can be done with three methods: -Sobel edge detection-Laplacian edge detection-Canny edge detection What is the best method for […]
