Learn the benefits and applications of local feature detection and extraction
Label objects in images.
Use the Computer Vision System Toolbox™ functions for image category classification by creating a bag of visual words.
Estimate camera intrinsics, extrinsics, and lens distortion parameters.
Calibrate a stereo camera, which you can then use to recover depth from images.
Detect and display speeded-up robust features (SURF) interest points.
Extract histogram of gradient (HOG) features from an image.
This example shows how to detect regions in an image that contain text.
This example shows how to automatically detect and track a face.
This example shows how to perform automatic detection and motion-based tracking of moving objects in a video from a stationary camera.
This example shows how to detect a particular object in a cluttered scene, given a reference image of the object.
This example shows how to track pedestrians using a camera mounted in a moving car.
This example shows how to evaluate the accuracy of camera parameters estimated using the
cameraCalibrator app or the
This example shows how to measure the diameter of coins in world units using a single calibrated camera.
Structure from motion (SfM) is the process of estimating the 3-D structure of a scene from a set of 2-D images.
Structure from motion (SfM) is the process of estimating the 3-D structure of a scene from a set of 2-D views.
