Method and system for marking key points in human face images

Abstract

The invention discloses a method for marking key points in human face images, and the method comprises the steps: pre-storing a plurality of human face images and the basic coordinates of preset key points in each human face image; loading and storing the human face images in advance before the human face images are displayed, searching the basic coordinates of preset key points in each human face image in advance, and storing the searched coordinates of preset key points in each human face image; displaying the human face images which are load and stored in advance, and carrying out the initial marking and displaying of the preset key points in each human face image according to the coordinates of the preset key points; presetting a plurality of image marking operation instructions and keyboard key triggering signals corresponding to the plurality of image marking operation instructions, receiving the triggering signals, obtaining the corresponding marking operation instructions, and carrying out the marking and storing of the preset key points in the human face images, the posture of a human face, and human face expressions according to the basic coordinates of the preset key points. The method and system achieves the quick and effective marking of the key points in the human face images while guaranteeing high quality, and improve the work efficiency of a user.

Description

technical field [0001] The invention relates to technical fields such as image processing, software engineering, and computer technology, and in particular to a method for marking key points in a human face picture and a marking system thereof. Background technique [0002] At present, with the continuous development of human science and technology, face recognition technology is becoming more and more popular in people's daily life. No matter in artificial intelligence research or public security applications, face recognition technology has always been a cutting-edge and popular technology. status. [0003] With the rapid development of the Internet economy, especially the recent introduction of the concept of "Internet Plus", face recognition technology has been pushed to a new climax. At present, in the financial field and the banking system, partial trials of face-based account opening and swiping cards have begun, which has prompted researchers around the world to int...

Problems solved by technology

The existing annotation system adopts the mode of combining the interface and the mouse in order to quickly get started with the annotation personnel, which easily leads to the low speed of annotating the key points in the face image and takes a lot of time. At the same time, the key points in the face image are now The amount of point labeling data is increasing day by day, and the number of data sometimes reaches tens of thousands or even millions. This requires that the labeling of key points in face pictures not only requires high quality, but also requires fast speed.

The existing labeling mode for key points in face pictures can no longer meet the needs of scientific research
