Evaluation of the wavelet image two-line coder: A low complexity scheme for image compression

作者：

Highlights：

• We provide a detailed analysis in terms of the wavelet image two-line coder (Wi2l).

• We evaluate the performance of Wi2l in comparison to Google WebP and JPEG2000.

• We measure the coding times on a 16-bit microcontroller.

• A finding is that Wi2l is competitive to the state-of-the-art in image compression.

• We provide the C source code of Wi2l for application on tiny camera sensor nodes.
