v3.0

This release is based on neural networks. I trained two versions of models:

robustness model

More robustness against compression, photo editing etc. But less visually similar to original image.

(MSerial#: RAWMS10RE5EP3)

visual similar model

More similar to original image but providing less robustness.

(MSerial#: RAWMS100RE5EP9)

There're no plans to release model training code as organizing those code takes too many efforts.

v1.8

Integrated a better random number generator
Added more contents to README

v1.6

I rewrite most of code and add following features:

• JPEG style quantization
• More flexible on which frequency bands to write data on frequency space
• Use reference blocks to provide robustness to image editing
• Add support to CbCr downsampling
• Re-designed the order determination algorithm, brining down complexity from O(N^2) to O(N)

v1.5

Significantly better performance!

v1.3

This JS library supports all browsers with HTML5.
