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…
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…
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…
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…
