The invention provides a measurement method for eye movement consistency among dynamic observers, which comprises the following steps: acquiring eye movement data of N observers when watching a video, and processing the eye movement data; obtaining the inter-observer eye movement consistency of a single observer through a single frame image in the processed eye movement data; repeating the steps until the eye movement consistency among all observers is obtained; and processing the inter-observer eye movement consistency of the observer to obtain a value of the dynamic observer eye movement consistency of the single-frame image. The invention also provides a prediction method for the eye movement consistency among the dynamic observers. A model is trained based on the data obtained by the measurement and calculation method for the eye movement consistency among the dynamic observers. The trained model is used to predict the eye movement consistency among the dynamic observers. The method is a method for predicting the eye movement consistency among observers of a video, the deep learning technology is applied, inter-frame motion characteristics are combined, and an accurate result is obtained.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for measuring and predicting eye movement consistency between dynamic observers and a terminal. Background technique [0002] In recent years, with the maturity of human eye gaze point detection equipment, the analysis of human visual system and human eye attention content has become the focus of attention in the field of computer vision graphics processing. Human gaze behavior is affected by many factors, such as age, education level, and physical condition of the observer. Inter-observer eye-movement coherence describes the degree to which the distribution of visual attention areas is dispersed when different subjects view the same material. [0003] Since the current research on visually salient regions has received extensive attention, researchers have proposed a large number of methods to predict visually salient regions. Inter-observer eye-moveme...
