CLAY: Conditional Visual Similarity Modulation in Vision-Language Embedding Space
Sohwi Lim, Lee Hyoseok, Jungjoon Park +1
Human perception of visual similarity is inherently adaptive and subjective, depending on the users' interests and focus. However, most image retrieval systems fail to reflect this…
Early Failure Detection and Intervention in Video Diffusion Models
Kwon Byung-Ki, Sohwi Lim, Nam Hyeon-Woo +2
Text-to-video (T2V) diffusion models have rapidly advanced, yet generations still occasionally fail in practice, such as low text-video alignment or low perceptual quality. Since d…
Measurement-Consistent Langevin Corrector for Stabilizing Latent Diffusion Inverse Problem Solvers
Lee Hyoseok, Sohwi Lim, Eunju Cha +1
While latent diffusion models (LDMs) have emerged as powerful priors for inverse problems, existing LDM-based solvers frequently suffer from instability. In this work, we first ide…
Patch-wise Retrieval: A Bag of Practical Techniques for Instance-level Matching
Wonseok Choi, Sohwi Lim, Nam Hyeon-Woo +4
Instance-level image retrieval aims to find images containing the same object as a given query, despite variations in size, position, or appearance. To address this challenging tas…
