The early detection of developmental disorders is key to child outcome, allowing interventions to be initiated that promote development and improve prognosis. Research on autism spectrum disorder (ASD) suggests behavioral markers can be observed late in the first year of life. Many of these studies involved extensive frame-by-frame video observation and analysis of a child's natural behavior. Although non-intrusive, these methods are extremely time-intensive and require a high level of observer… Expand
A Computer Vision System to Assist the Early Screening of Autism Spectrum Disorder
A computer vision system to assist the early screening of autism from an engineering perspective is proposed and an experimental paradigm of giving instructions when subjects are playing with toys is well-designed. Expand
Automatic Detection of ADHD and ASD from Expressive Behaviour in RGBD Data
This work presents a novel methodology to aid diagnostic predictions about the presence/absence of ADHD and ASD by automatic visual analysis of a persons behaviour by using state of the art facial expression analysis based on Dynamic Deep Learning and 3D analysis of behaviour. Expand
Measuring the Variabilities in the Body Postures of the Children for Early Detection of Autism Spectrum Disorder (ASD)
A computational framework to semi-automate the diagnosis process of Autism Spectrum Disorder by using human action recognition (HAR) algorithm and skeleton representation to show the arm asymmetrical in arm flapping movement which indicates the possibility of ASD signs by extracting the body pose into stickman model. Expand
Using 2D Video-based Pose Estimation for Automated Prediction of Autism Spectrum Disorders in Preschoolers
The hypothesis that a deep neural network trained on the non-verbal aspects of social interaction can effectively differentiate between children with ASD and their typically developing peers is tested and carries reasonable promises that a reliable machine-learning-based ASD screening may become a reality not too far in the future.

Leveraging Computer Vision and Humanoid Robots to Detect Autism in Toddlers
Autism Spectrum Disorder is a developmental disorder often characterized by limited social skills, repetitive behaviors, obsessions, and/or routines. Using the small humanoid robot NAO, we designedExpand
Automatic recognition of therapy progress among children with autism
The study identifies a subset of parameters which appear to be better predictors of therapy progress than others and might be implemented in a tool to support both therapists and parents of autistic children. Expand
Motor abnormalities as a putative endophenotype for Autism Spectrum Disorders
The evidence that supports the use of motor abnormalities as a putative endophenotype for ASDs is summarized and it is proposed that stratifying patients based on motor development could be useful not only as an outcome predictor and in identifying more specific treatments for different ASDs categories, but also in exposing neurobiological mechanisms.

Characterizing autistic features among preschoolers interacting with social robots
Emerging evidence suggests that individuals with autism spectrum disorder show interests or preferences for specific types of nonsocial information, including various forms of technology such asExpand
On the Estimation of Children's Poses
Different state of art approaches for human pose estimation on a benchmark dataset useful to understand their performances when subjects are children are compared, revealing that accuracy of the state ofArt methods drop significantly, opening new challenges for the research community. Expand
Gyroscope-Based Game Revealing Progress of Children with Autism
The proposed approach combines diverse approaches: e-technologies and mobile applications for autism, behavioral metrics derived from gyroscope and game state with machine learning methods to find interconnections between the metrics and the progress of a child. Expand

  • 2012
Computer vision tools to measure and identify ASD behavioral markers based on components of the Autism Observation Scale for Infants (AOSI) are provided, with results that provide insightful knowledge to augment the clinician's behavioral observations obtained from real in-clinic assessments. Expand
Behavioral manifestations of autism in the first year of life
A longitudinal study of high‐risk infants, all of whom have an older sibling diagnosed with an autistic spectrum disorder, indicates that by 12 months of age, siblings who are later diagnosed with autism may be distinguished from other siblings and low‐risk controls on the basis of several specific behavioral markers. Expand
Absence of preferential looking to the eyes of approaching adults predicts level of social disability in 2-year-old toddlers with autism spectrum disorder.
The results indicate that in 2-year-old children with autism, this behavior is already derailed, suggesting critical consequences for development but also offering a potential biomarker for quantifying syndrome manifestation at this early age. Expand
The Autism Diagnostic Observation Schedule—Toddler Module: A New Module of a Standardized Diagnostic Measure for Autism Spectrum Disorders
A modified ADOS, the ADOS Toddler Module (or Module T), was used in 360 evaluations and the traditional algorithm “cutoffs” approach yielded high sensitivity and specificity, and a new range of concern approach was proposed. Expand
Timing of identification among children with an autism spectrum disorder: findings from a population-based surveillance study.
The large gap between the age at which children can be identified and when they actually are identified suggests a critical need for further research, innovation, and improvement in this area of clinical practice. Expand
Eshkol-Wachman movement notation in diagnosis: the early detection of Asperger's syndrome.
Evidence is presented that abnormal movement patterns can be detected in Asperger's syndrome in infancy, which suggests that AS can be diagnosed very early, independent of the presence of language. Expand

A developmental model of risk, risk processes, symptom emergence, and adaptation in ASD is described that offers a framework for understanding early brain plasticity in ASD and its role in prevention of the disorder. Expand
Visual fixation patterns during viewing of naturalistic social situations as predictors of social competence in individuals with autism.
A novel method of quantifying atypical strategies of social monitoring in a setting that simulates the demands of daily experience is reported, finding that fixation times on mouths and objects but not on eyes are strong predictors of degree of social competence. Expand
The influence of visual saliency on fixation patterns in individuals with Autism Spectrum Disorders
It was found that social features in scenes (heads) captured attention much more than visually salient features, even in individuals with ASD, and visual saliency impacts fixation location in a similar manner in Individuals with ASD and those with typical development. Expand
Analysis of unsupported gait in toddlers with autism
The specificity of motor disturbances identified in autism (postural asymmetry) is consistent with previous findings that implicated cerebellar involvement in the motor symptoms of autism. Expand
