Abstract

The invention discloses an emotion analysis system based on facial expression. The invention relates to the technical field of face recognition. The invention comprises an image acquisition module, adata port, a data port, a display and an image acquisition module, which are used for collecting real-time picture data information on the spot and transmitting the collected data information to a processor. The data port is used for importing the external picture library data into the processor; The database is used for storing the results of data analysis or importing the stored data informationinto the processor. The display is used for displaying the data result information processed by the processor. The invention realizes accurate positioning and recognition of the face by selecting eyecorner points, nose wing points and mouth corner points. In addition, through light compensation, image grayscale processing, Gaussian smoothing, equalization histogram processing, contrast enhancement, binary transformation and other effective ways to improve the accuracy of image recognition process, to ensure the correctness of data analysis results.

Description

technical field [0001] The invention belongs to the technical field of face recognition, in particular to an emotion analysis system based on facial expressions. Background technique [0002] Face recognition technology has been used in many fields, and face recognition technology has played a pivotal role. [0003] Now people propose to use the geometric feature detection method for face recognition, and the selected features are representative eyes, ears, mouth, and nose for facial contour recognition; however, deviations are prone to occur in the existing recognition process, which affects the accuracy of data detection. result. Contents of the invention [0004] The purpose of the present invention is to provide an emotional analysis system based on facial expressions, which can realize accurate positioning and recognition of the face by selecting the corners of the eyes, the wings of the nose, and the corners of the mouth; in addition, through light compensation, ima...
