Feature descriptors (Descriptor extractor): After detecting keypoints we go on to compute a descriptor for every one of them. "A local descriptor a compact representation of a point's local neighbourhood. In contrast to global descriptors describing a complete object or point cloud, local descriptors try to resemble shape and appearance only in a local neighborhood around a point and thus are very suitable for representing it in terms of matching. " (Dirk Holz et al. ). OpenCV options: FREAK DAISY LATCH LUCID BRIEF Correspondence Estimation (descriptor matcher): The next task is to find correspondences between the keypoints found in both erefore the extracted features are placed in a structure that can be searched efficiently (such as a kd-tree). Usually it is sufficient to look up all local feature-descriptors and match each one of them to his corresponding counterpart from the other image. However due to the fact that two images from a similar scene don't necessarily have the same number of feature-descriptors as one cloud can have more data than the other, we need to run a separated correspondence rejection process.

OpenCV 'Open Source Computer Vision Library' is an open-source library that includes several hundreds of computer vision algorithms. Using OpenCV, you could pretty much do every Computer Vision task that could ever be imagined! Real-life problems require you to utilize multiple building blocks together in order to achieve the desired outcome. So, you just have to understand what modules and functions are needed to get what you want! In the next few minutes, we shall quickly dive into what OpenCV can do out of the box! © Tanvi Penumudy 2020 — Rose Painting: Before and After Enhancement with OpenCV The following topics have been precisely covered in the due course of the article — Installation and Importing Getting Started Edge Detection Feature Extraction Feature Matching Transformations Face Detection Working with Videos Additional Resources and References Installation Can be done on your local machine via Python command prompt pip install opencv-python Refer opencv-python· PyPI for troubleshooting Importing OpenCV import cv2 # OpenCV-Python It's as simple as that!
