Problems solved by technology

However, the existing computer screening system mainly induces smiles by playing videos. This method not only restricts children from wearing devices or sitting on fixed devices and cannot move freely, but also is difficult to simulate real life, especially difficult to simulate the interaction with people in real social scenes. social communication

Abstract

The invention discloses an early screening system for autism based on smile paradigm and audio-video behavior analysis, comprising: a data collection module for collecting audio-video data throughout the test; a pre-processing module for synchronously aligning the collected audio-video data, The time and type of different funny stimuli are marked in paragraphs; the feature extraction module analyzes each feature frame by frame for the preprocessed data; the training classification module is used to train the classifier for feature extraction of segmented video data, and The paradigm trains the autism risk coefficient prediction classifier model; the prediction module uses the classifier model to score the extracted features, and scores the entire paradigm. The invention is used for the early screening of autism, so that the screening test is more standardized and structured, and the test evaluation is more accurate, readable and easy to explain.

Description

technical field [0001] The invention relates to the fields of speech processing and image processing, in particular to an early screening system for autism based on a social and shared smile paradigm and audio and video behavior analysis, which collects audio and video data when an evaluator induces a smile and a subject. Response image data when induced and analyzed to evaluate a system for predicting autism spectrum disorder. Background technique [0002] Autism spectrum disorder (ASD) has received more and more attention from society. In China, the number of children with autism between the ages of 0 and 14 is between 3 million and 5 million. The current assessment methods for autism mainly focus on three aspects: language communication disorder, social interaction disorder, and repetitive stereotyped behavior. An effective and accurate assessment of ASD requires the observation of children and the co-trials of medical professionals with clinical experience. [0003] I...
