Objectives
• Kansei Evaluation based on Computer Vision for a traditional
Vietnamese women’s cloth named Ao dai
• Image features for outside environment images and Aodai images
are described by Color Coherence Vector
• Learning algorithms are used to learn Kansei relations among
outside environment images and Kansei words for Aodai.
• The system can recommends which Ao dai is suitable for a woman
on an occasion based on own characters and physical conditions
with the environment about any cases

Aodai - Introduction
• Early versions of Vietnamese Aodai appeared from 17th century
• Design of Aodai has also been changed with the country history

Discussion
• This research proposes a Kansei Evaluation System for traditionalVietnamese Aodai.
• The system can advise which Aodai clothes a woman should wear in an occasion
– Inputs of the system are descriptions of outing environments with thewearer’s characters and feelings
– Outputs are list of suitable clothes that fit her feelings with emotions of outside people in that occasion.
• Future Topics
– Investigating other image representation methods – Integrating conspicuity factors (harmony, discriminability and visibility)
– Extending Aodai images with outgoing scene backgrounds
