Opencv python tutorials feature detection and description. It takes the descriptor of one feature in first set and. Feature matching homography to find objects. We will discuss the algorithm and share the code in python to design a simple stabilizer using this method in opencv.

In this chapter we will mix up the feature matching and findhomography from calib3d module to find known objects in a complex image. Feature matching is going to be a slightly more impressive version of template matching where a perfect or very close to perfect match is required. Basics of brute force matcher. It is slow since it checks match with all the features.

Feature matching between images in opencv can be done with brute force matcher or flann based matcher. This can be done using the drawmatches function in opencv. Bf matcher matches the descriptor of a feature from one image with all other features of another image and returns the match based on the distance. Next let s try and match the features from image 1 with features from image 2.

So what we did in last session. Feature detection and description. Concepts used for template matching. Brute force matcher is simple.

We used a queryimage found some feature points in it. We will mix up the feature matching and findhomography from calib3d module to find known objects in a complex image. This post s code is inspired by work presented by nghia ho here and the post from. Here we will see a simple example on how to match features between two images.

In this post we will learn how to implement a simple video stabilizer using a technique called point feature matching in opencv library.
