The invention provides an emotional feature recognition system and method for classroom teaching. The method comprises the following steps: acquiring facial image data and behavior time sequence data of a student in a classroom teaching process through a camera after the student clearly knows and agrees to authorize; determining dynamic expression features of the student through a preset facial analysis model according to the facial image data; on the basis of a head posture change sequence and an eye fixation focus track extracted from behavior time sequence data, constructing concentration indexes and confusion indexes of students in different teaching links through multi-feature fusion; and when it is detected that a preset condition is met, generating an emotional feature tag of the student in classroom teaching based on the dynamic expression feature, the concentration index and the confusion index, and pushing the emotional feature tag to a teacher terminal for visual display. By adopting the scheme of the invention, multi-modal feature fusion analysis of the classroom state of the student can be realized, so that the accuracy of classroom teaching regulation and control is improved.

This invention discloses a method and apparatus for visualizing four-region facial segmentation based on a 3D model, relating to the field of image processing technology. The method includes: calculating the unit normal of each vertex; extracting specular transition rings and generating a ring buffer set; performing weighted statistical analysis on mesh vertices using suppression weights to establish the left-right and top-bottom axes of the 3D face mesh; projecting the vertex set onto the left-right and top-bottom axes, and determining the left-right segmentation boundary and top-bottom segmentation threshold based on the ring buffer set to generate a four-region mask; performing ring attenuation backfilling processing on the scalar values ​​of the vertices to be visualized based on geodesic distance to obtain the visualization scalar values, and calculating the statistical indicators of each region based on the suppression weights and the four-region mask. This invention can significantly improve the stability and accuracy of 3D facial analysis.

The present disclosure relates to a system (102) and a method for facial analysis based on facial areas of interest (ROIs) in a vehicle. The system (102) comprises an image acquisition unit (106) that captures images of the user. The system (102) comprises a detection module (108) that detects one or more landmarks corresponding to one or more facial features in the images. The system (102) comprises a control unit (104) for analyzing one or more detected landmarks to determine one or more unobstructed ROI landmarks and one or more concealed ROI landmarks in one or more images. The control unit (104) constructs a predefined area based on one or more unobstructed ROI landmarks in one or more images.Control unit (104) calculates one or more facial features based on one or more unobstructed ROI reference points and a predefined area. Control unit (104) performs a facial feature analysis based on the classification of unobstructed ROI reference points into face-selected reference points and non-face-selected reference points in images (302).

1. Name of the product in this design: Graphical User Interface for Facial Analysis Display of Electronic Device. 2. Purpose of this design: An electronic device. 3. The key design feature of this product is its graphical user interface. 4. The image or photo that best illustrates the design points: Interface change state diagram 1. 5. Purpose of the Graphical User Interface: This graphical user interface is used for facial analysis. After the user uploads a photo by clicking the "Upload Photo and Receive Report" button in the main view, the interface transitions to state 1. The system automatically scans the photo to analyze the user's facial features, resulting in state 2. Analysis of the corresponding facial features appears below the scan progress. After the analysis is complete, the interface transitions to state 3. Clicking the "Add" button in state 3 leads to state 4. State 4 is the facial analysis report page. Swiping up on state 4 leads to state 5 through 8. Gray blocks in the interface represent replaceable images or videos, and "XXXX" represents character or text content.
