Lecture 10: Scalable Coding

Fundamentals. Main ideas. Applications

Scalability modes

• Quality or SNR scalability
• Spatial scalability
• Temporal scalability
• Frequency scalability or data partition
• Hybrid scalability
• Coarse- and fine-granularity scalability

Image scalable coding

• Embedded zero-tree wavelet coding (EZW)
• Set partitioning in hierarchical trees (SPIHT)
• JPEG2000

Video scalable coding

• Layer coding: coarse granularity
• Fine-granularity video coding
• 3D sub-band video coding
