文摘
- •
Visual sensor nodes have little RAM and lined-based external memory.
- •
Existing scalable wavelet image coding approaches require large RAM.
- •
A novel line-based scalable wavelet image coder for low-RAM sensors is developed.
- •
The novel coding approach requires RAM memory for only two image lines.
- •
The coder achieves the RD performance of SPHIT and has no scalable coding overhead.
