"Which options are machine vision applications?" Target detection and recognition, image classification and labeling, feature extraction and description, etc.

1. Target detection and recognition: Identify and locate specific targets in images or videos, such as faces, vehicles and objects, through machine vision algorithms.

2. Image classification and labeling: classify images into different categories, add labels or descriptions to images, and classify animal images into cats, dogs, birds, etc.

3. Feature extraction and description: extract meaningful features from the image for subsequent analysis and recognition, and extract features such as edge, texture and color of the image.
