Local texture features based on Contourlet transform and local binary pattern are investigated to represent the facial characteristics. A support vector machine classifier is then used to discriminate between normal and abnormal cases. Accuracy, precision and recall are used to evaluate the method. After validating the method, this technology will then be expanded to perform similar functions to assist in the detection of other dysmorphic syndromes.\n\nBy using photography and image analysis this automated assessment tool would have the potential to improve the diagnosis rate and allow for remote, non-invasive diagnostic evaluation for dysmorphologists in a timely manner.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Pediatric subject with Down syndrome.\n* Healthy pediatric siblings of a subject with Down syndrome and/or other individuals with another genetic referral to serve as a control group.\n* Subject must be less than 18 years old.\n\nExclusion Criteria:\n\n* Subjects 18 years or older.'}, 'identificationModule': {'nctId': 'NCT02651493', 'briefTitle': 'Digital Dysmorphology Project', 'organization': {'class': 'OTHER', 'fullName': "Children's National Research Institute"}, 'officialTitle': 'Down Syndrome Detection From Facial Photographs Using Machine Learning Techniques', 'orgStudyIdInfo': {'id': 'Pro00003506.'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Down syndrome', 'description': 'photographs of individuals less than 18 yo with Down syndrome', 'interventionNames': ['Device: photographs']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Control group', 'description': 'photographs of individuals less than 18 yo with a genetic referral (not Down syndrome) or a healthy sibling to a child with Down syndrome', 'interventionNames': ['Device: photographs']}], 'interventions': [{'name': 'photographs', 'type': 'DEVICE', 'description': 'computer based program to analyze photographs (computer-aided diagnosis (CAD) software)', 'armGroupLabels': ['Control group', 'Down syndrome']}]}, 'contactsLocationsModule': {'locations': [{'zip': '20010', 'city': 'Washington D.C.', 'state': 'District of Columbia', 'status': 'RECRUITING', 'country': 'United States', 'contacts': [{'name': 'Sara Alyamani, BS', 'role': 'CONTACT', 'email': 'salyaman@childrensnational.org', 'phone': '202-476-6099'}, {'name': 'Kevin Cleary, PhD', 'role': 'CONTACT', 'email': 'kcleary@childrensnational.org', 'phone': '202 476 3809'}, {'name': 'Kevin Cleary, PhD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Marius Linguraru, PhD', 'role': 'SUB_INVESTIGATOR'}], 'facility': "Children's National", 'geoPoint': {'lat': 38.89511, 'lon': -77.03637}}], 'centralContacts': [{'name': 'Kevin Cleary, PhD', 'role': 'CONTACT', 'email': 'kcleary@childrensnational.org', 'phone': '202 476 3809'}, {'name': 'Marius Linguraru, PhD', 'role': 'CONTACT', 'email': 'MLingura@childrensnational.org', 'phone': '202 476 3059'}], 'overallOfficials': [{'name': 'Kevin Cleary, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': "Children's National Research Institute"}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Kevin Cleary', 'class': 'OTHER'}, 'collaborators': [{'name': "Children's National Research Institute", 'class': 'OTHER'}, {'name': 'George Washington University', 'class': 'OTHER'}, {'name': 'Chiang Mai University', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR_INVESTIGATOR', 'investigatorTitle': 'PhD', 'investigatorFullName': 'Kevin Cleary', 'investigatorAffiliation': "Children's National Research Institute"}}}}
