Problems solved by technology
At present, the main method of facial expression recognition is to establish models or topological structures of various moods such as sadness, corresponding feature areas such as eyes, mouth, eyebrows, etc., and extract feature points in the image such as eyes. pixels, eyebrow pixels, etc., or geometric feature areas such as eye feature areas, mouth feature areas, and compare these feature points or geometric feature areas with established models or topological structures. This process requires The pixel requirements of the image are relatively high, resulting in low recognition of image expressions by the existing technology

The present invention provides an expression recognition method and device. By determining the mapping relationship between expression standard values and psychological states, the information of at least one target area in an image is determined; and the expression value of the image is calculated according to the information of the at least one target area. ; Comparing the calculated expression value of the image with the determined expression standard value; according to the mapping relationship between the expression standard value and the mental state, determine the psychological state corresponding to the at least one target area, so that Improved recognition of facial expressions in images.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to an expression recognition method and device. Background technique [0002] Facial expression recognition refers to intelligent analysis and detection of facial expressions in human face images to determine the mood of the recognized object in the human face image, such as sad, happy, hungry, etc. At present, the main method of facial expression recognition is to establish models or topological structures of various moods such as sadness, corresponding feature areas such as eyes, mouth, eyebrows, etc., and extract feature points in the image such as eyes. pixels, eyebrow pixels, etc., or geometric feature areas such as eye feature areas, mouth feature areas, and compare these feature points or geometric feature areas with established models or topological structures. This process requires The pixel requirements of the image are relatively high, resulting in low recogniti...
