Context-Aware Adaptive Mask Selection for Consistent Referring Video Object Segmentation
Jun-Hyeok Seo, Young-Woo Youn, Wonjun Choi, and Dong-Gyu Lee
KAIC, 2025

This paper proposes a context-aware adaptive mask selection framework for referring video object segmentation (RVOS). The method integrates CLIP-based keyframe selection, mask consistency scoring, text-guided object number determination, and temporal mask interpolation to ensure both temporal stability and accurate multi-object segmentation.

Enhancing Detail Quality in Latent Diffusion Model-Based Super-Resolution via Multi-Scale Discrete Wavelet Transform
Jun-Hyeok Seo, and Dong-Gyu Lee
KTCP, 2025

This paper proposes a multi-scale discrete wavelet transform framework designed to enhance the detail quality of super-resolution (SR) methods based on latent diffusion model. Experimental results on benchmark datasets demonstrate that the proposed framework outperforms previous methods, effectively improving the detail quality of super-resolved images.

Multi-Perspective LVLM Prompting for Robust Zero-Shot Image Classification
Wonjun Choi, Jeong-Cheol Lee, Jun-Hyeok Seo, and Dong-Gyu Lee
CVPRw, 2025

This paper proposes a multi-perspective prompt-based framework for zero-shot image classification using LVLMs, enhancing robustness by integrating object-aware, intent-aware, and reason-aware prompts, and achieving superior performance through ensemble prediction on the VizWiz dataset.

Diffusion Model Based Image Super-Resolution with Multi-Scale High Frequency Error Maps
Jun-Hyeok Seo, and Dong-Gyu Lee
KSC, 2024Best Presentation Paper Award

This paper proposes a diffusion model-based image super-resolution framework using multi-scale high-frequency error maps, enabling accurate restoration of image details and outperforming existing methods on benchmark datasets.

Robust Captcha Image Recognition Algorithm Using Transformer-Based OCR Model
Junhyeok Seo, Seongjin Jang, Minjun Kim, and Hyeonju Yoon
KIIT, 2023Bronze Award

This paper proposes a robust OCR algorithm using the end-to-end Transformer-based TrOCR model, achieving a Character Error Rate (CER) of approximately 0.08 and significantly outperforming Tesseract OCR and EasyOCR.

Deep Learning-Based Vehicle Damage Area Detection System using Semantic Segmentation
Junhyeok Seo, and Hyeonju Yoon
KCC, 2023

This paper proposes a system for detecting vehicle damage areas through semantic segmentation using the UNet++ model, achieving pixel-level accuracy with an average IoU of 0.94 and comparing its performance with the conventional U-Net model.

Segmentation of Stain Area in Clothing Images using UNet++
Junhyeok Seo, Gunwook Kim, Junsu Park, and Sungyoung Kim
KIIT, 2023Bronze Award

This paper proposes a deep learning-based technique for detecting stains in clothing images using a UNet++ model with an EfficientNet encoder pre-trained on ImageNet, achieving an average IoU of approximately 0.9589.

Domain Dictionary Construction for Automatic Analysis of Subject CQI Reports
Gunwoo Kim, Junsu Park, Junhyeok Seo, Yuchul Jung, and Hyeonju Yoon
KIIT, 2022Silver Award

This paper analyzes various words used in CQI reports and constructs a domain dictionary to provide the foundation for future automatic analysis of such reports.

Deep Learning-Based Vehicle Model and License Plate Identification System using Vehicle Image
Junhyeok Seo, and Hyeonju Yoon
KIIT, 2022Gold Award

This paper proposes a vehicle model recognition and license plate identification system using YOLOv5, enabling both tasks simultaneously and reducing computational cost compared to previous methods.
