What is keypoint detection?

Keypoint detection involves simultaneously detecting people and localizing their keypoints. Keypoints are the same thing as interest points. They are spatial locations, or points in the image that define what is interesting or what stand out in the image.

What is keypoint regression?

2.1 Keypoint Regression

The semantic keypoints detection aims to find the numerical coordinates of a set of pre-defined facial landmarks (e.g., left eye, right eye, nose, left mouth corner, right mouth corner, etc.).

What is human key point?

The idea of Keypoint Detection is to detect interest points or key locations in an image. These could be: the facial landmarks (such as nose-tip, eye-corners, face-boundary etc ) or the body-joints ( shoulders, wrists, ankles ) in a person. or the corners and blobs in an image.

What is image keypoint?

Image Keypoint: a distinctive image feature that can be detected repeatably despite changes in 1) image scale (resolution), 2) illumination and noise, and 3) image orientation and perspective.
