Entropy encoder for low-power low-resources high-quality CFA image compression

作者：

Highlights：

• DCT coefficients from different color planes have similar statistics.

• Usage of the similarity between the CFA channels increases the efficiency of the entropy encoder.

• Alternating coding of coefficients from different color planes is more efficient.

• Proper ordering of coefficients before entropy encoding reduces memory requirements.
