WHAT
• Motion 이 가진 content( 내용 ) 를 보존하면서 새로운 style 로 변환
Our style translation system transforms a normal walk (TOP)into a sneaky crouch (MIDDLE) and a sideways shuffle (BOTTOM).

WHAT
• Still image 에서 motion 을 표현하기 위한 action synopsis 를 생성
Action synopsis analyzes the motion-curve embedded in a low dimensional space (a); super-positioning of carefully selected poses (b) vs. uniform sampling (c).

WHY
• Summary, abstraction, motion description 의 목적으로 still imagery 에서 motion 을 illustrating 하는 것이 중요함
KUCG Jong-In Choi 10
HOW (1/2)
• Extracting motion aspects– Joint position, angle, angle, angular velocity
• Dimensionality reduction– Affinity matrix
• Pose selection– Local extreme points along motion curve
• Synopsis illustration– Illustration by selected images
