Find Object in Cluttered Scene Using Image Point Features

Detect a particular object in a cluttered scene, given a reference image of the object.

• 打开脚本

Measuring Planar Objects with a Calibrated Camera

Measure the diameter of coins in world units using a single calibrated camera.

• 打开实时脚本

Automatically Find Image Rotation and Scale

Demonstrates how to automatically determine the geometric transformation between two images. Specifically, when one image is distorted in relation to another due to rotation and scaling, the functions detectSIFTFeatures and estgeotform2d can be employed to identify the rotation angle and scale factor. Subsequently, these parameters can be used to transform the distorted image back to its original appearance.

• 打开脚本

Motion-Based Multiple Object Tracking

Perform automatic detection and motion-based tracking of moving objects in a video from a stationary camera.

• 打开脚本

Create Panorama

Automatically stitch multiple images into panorama. The procedure for image stitching is an extension of feature based image registration. Instead of registering a single pair of images, multiple image pairs are successively registered relative to each other to form a panorama.
