# Lossless Compression on ImageNet64 (test) Source: [Lossless Compression on ImageNet64 (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:37:24.812Z Evaluation of lossless image compression models on the test split of the ImageNet64 dataset, typically measured using Bits Per Dimension (BPD). A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Lossless Compression | | Dataset (including any stated split) | ImageNet64 (test) | | Metric | BPD | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 27 of 27 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [BPD](): Lower is better; unit: SCALAR. ## Recorded results | Method | BPD | Result date | Report paper | | --- | --- | --- | --- | | NeLLoC (r = 3) | 3.53 | Not recorded | 68fa6b6d1e209131cea2e47a | | NeLLoC (r = 1) | 3.55 | Not recorded | 68fa6b6d1e209131cea2e47a | | NeLLoC (r = 0) | 3.63 | Not recorded | 68fa6b6d1e209131cea2e47a | | NeLLoC (r = 3) | 3.69 | Not recorded | 68fa6b6d1e209131cea2e47a | | LBB | 3.7 | Not recorded | 68fa6b2d1e209131cea2c9cd | | LBB | 3.7 | Not recorded | 68fa6b6d1e209131cea2e47a | | NeLLoC (r = 1) | 3.74 | Not recorded | 68fa6b6d1e209131cea2e47a | | iVPF | 3.75 | Not recorded | 68fa6b2d1e209131cea2c9cd | | iVPF | 3.79 | Not recorded | 68fa6b2d1e209131cea2c9cd | | IDF++ | 3.81 | Not recorded | 68fa6b2d1e209131cea2c9cd | | NeLLoC (r = 0) | 3.86 | Not recorded | 68fa6b6d1e209131cea2e47a | | HiLLOC | 3.89 | Not recorded | 68fa6b6d1e209131cea2e47a | | HiLLOC | 3.9 | Not recorded | 68fa6b2d1e209131cea2c9cd | | IDF | 3.9 | Not recorded | 68fa6b2d1e209131cea2c9cd | | IDF | 3.9 | Not recorded | 68fa6b6d1e209131cea2e47a | | IDF | 3.94 | Not recorded | 68fa6b2d1e209131cea2c9cd | | IDF | 3.94 | Not recorded | 68fa6b6d1e209131cea2e47a | | FLIF | 4.19 | Not recorded | 68fa6b2d1e209131cea2c9cd | | FLIF | 4.19 | Not recorded | 68fa6b6d1e209131cea2e47a | | L3C | 4.3 | Not recorded | 68fa6b6d1e209131cea2e47a | | HiLLOC | 4.46 | Not recorded | 68fa6b6d1e209131cea2e47a | | WebP | 4.64 | Not recorded | 68fa6b6d1e209131cea2e47a | | L3C | 4.77 | Not recorded | 68fa6b6d1e209131cea2e47a | | IDF++ | 4.81 | Not recorded | 68fa6b6d1e209131cea2e47a | | JPEG2000 | 5.1 | Not recorded | 68fa6b6d1e209131cea2e47a | | PNG | 5.71 | Not recorded | 68fa6b2d1e209131cea2c9cd | | PNG | 5.71 | Not recorded | 68fa6b6d1e209131cea2e47a | ### NeLLoC (r = 3) BPD: 3.53.
