Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T.

Reproducibility Variable Result LLM Response
Research Type Experimental Comprehensive quantitative and qualitative evaluation on PIE benchmark and DAVIS dataset shows that Free Inv remarkably outperforms conventional DDIM inversion, and is competitive among previous state-of-the-art inversion methods, with superior computation efficiency.
Researcher Affiliation Collaboration 1 Beihang University, 2 HUJING Digital Media & Entertainment Group
Pseudocode No The paper describes the methodology in Section 3, using mathematical formulations and descriptive text, but does not include a distinct pseudocode block or algorithm figure.
Open Source Code Yes Code is available at https://github.com/yuxiangbao/ Free Inv.
Open Datasets Yes Comprehensive quantitative and qualitative evaluation on PIE benchmark and DAVIS dataset shows that Free Inv remarkably outperforms conventional DDIM inversion
Dataset Splits No Dataset. Following previous works [17, 50], we employ the PIE-benchmark [17] and its officially released code to quantitatively evaluate image editing results from Free Inv and the compared methods. PIE-benchmark consists of 700 images of resolution 512 512, the content of which is from nature or artificial generation.
Hardware Specification No Table 1 and Figure 6 provide memory usage (MB) and time (Seconds) for experiments, but they do not specify the exact GPU or CPU models used, only the amount of memory.
Software Dependencies Yes In our experiments, unless otherwise stated, we adopt Stable Diffusion [36] 1.5 with a 50-step DDIM schedule for U-Net based methods, and FLUX.1-dev [1] (abbr. FLUX) with a 25-step schedule for Di T based methods.
