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

• The most popular style is – A long dress that fits tightly around the women's upper torso

– Emphasizes women's bust and curves

• Hue colors and decorating characters depend on her age andoutgoing environments

– Young girls dressed in pure white

– Office women in delicate pastels with slight decoration

– Middle-aged married women in strong, rich colors and decoration

Selecting Kansei Words for Aodai

• From common adjectives often used to say about clothand emotion, we

– collect 34 words

– clarify them into 3 groups:

• Elegance

• Active/Energetic

• Inactive Groups

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
