1. Synthetic Data

1-1. Need for Synthetic Data

• Real data = Public Dataset + 직접 만들기
• Synthetic Data
• cost effective

1-2. SynthText

• image data + word data
• Depth estimation → For realistic synthetic data

1-3. SynthText3D & UnrealText

• Synth Text 3D : 가상 세계를 이용한 텍스트 이미지 합성

• UnrealText : 3D virtual Engine을 이용

1-4. How to Use

Pretraining

• ImageNet pretraining → Synthetic Dataset pretraining → Target Dataset Fine-Tuning

Weakly Supervised Learning

• Character-level detection
