Progressive coding of error-diffused bilevel images

Chul Soo Lee, Hyun Wook Park
2003 Journal of Electronic Imaging (JEI)  
After reducing the image size, we encode an error-diffused bilevel image progressively from the lowest resolution image to the highest resolution image.  ...  Thus, the resolution of the error-diffused bilevel images can be reduced by repetition of the inverse halftoning and rehalftoning processes.  ...  Progressive Coding of Error-Diffused Bilevel Images Resolution Reduction by Inverse Halftoning and Rehalftoning To combine a progressive coding function with the twopass approach, we must reduce the  ...

Near-lossless/lossless compression of error-diffused images using a two-pass approach

Chul Soo Lee, HyunWook Park
2003 IEEE Transactions on Image Processing  
This paper proposes a new bilevel image compression for error-diffused images, which is based on Bayes' theorem. The proposed coding procedure consists of two passes.  ...  It compresses bilevel images with high performance, but it shows relatively low performance in compressing error-diffused halftone images.  ...  When two progressive coding algorithms are applied to error-diffused images, the proposed algorithm works better than the progressive coding of the JBIG.  ...

Bit Prioritization in Variational Autoencoders via Progressive Coding

Rui Shu, Stefano Ermon
2022 International Conference on Machine Learning  
We do so by leveraging the progressive coding hypothesis, which claims hierarchical latent variable models that are good at progressive lossy compression will generate high-quality samples.  ...  Our work lends further support to the progressive coding hypothesis and demonstrates that this hypothesis should be exploited when designing variational autoencoders.  ...  We formalize the principle of progressive coding and show that the diffusion model objective can be derived as a special application of this principle. 2.  ...
