ROI-Aware Multiscale Cross-Attention Vision Transformer for Pest Image Identification

no code implementations28 Dec 2023 Ga-Eun Kim, Chang-Hwan Son

More importantly, for the new challenging dataset IP102(CBSS) that contains only pest images with complex backgrounds and small sizes, the proposed model can maintain high recognition accuracy, whereas that of other SOTA models decrease sharply, demonstrating that our model is more robust to complex background and scale problems.

Heavy Rain Face Image Restoration: Integrating Physical Degradation Model and Facial Component Guided Adversarial Learning

no code implementations18 Apr 2022 Chang-Hwan Son, Da-Hee Jeong

Unlike traditional image degradation models (IDM), such as rain removal and superresolution, this study addresses a new IDM referred to as a scale-aware heavy rain model and proposes a method for restoring high-resolution face images (HR-FIs) from low-resolution heavy rain face images (LRHR-FI).

New Encoder Learning for Captioning Heavy Rain Images via Semantic Visual Feature Matching

no code implementations28 May 2021 Chang-Hwan Son, Pung-Hwi Ye

To achieve this, a target encoder is initially trained in an encoder-decoder framework to associate visual features with semantic words.

Inverse Halftoning Through Structure-Aware Deep Convolutional Neural Networks

1 code implementation2 May 2019 Chang-Hwan Son

The subnetwork for the image structure prediction is trained using the mini-batch gradient descent algorithm given the halftoned patches and gradient patches, which are fed into the input and loss layers of the subnetwork, respectively.

Apple Leaf Disease Identification through Region-of-Interest-Aware Deep Convolutional Neural Network

no code implementations25 Mar 2019 Hee-Jin Yu, Chang-Hwan Son

The two subnetworks exhibit the architecture types of an encoder-decoder network and VGG network, respectively; subsequently, they are trained separately through transfer learning with a new training set containing class information, according to the types of leaf diseases and the ground truth images where the background, leaf area, and spot area are separated.

Multimodal Fusion via a Series of Transfers for Noise Removal

no code implementations22 Jan 2017 Chang-Hwan Son, Xiao-Ping Zhang

Different from conventional fusion approaches, the proposed method conducts a series of transfers: contrast, detail, and color transfers.

Near-Infrared Coloring via a Contrast-Preserving Mapping Model

no code implementations3 Oct 2016 Chang-Hwan Son, Xiao-Ping Zhang

This paper introduces a new coloring method to add colors to near-infrared gray images based on a contrast-preserving mapping model.

Rain Removal via Shrinkage-Based Sparse Coding and Learned Rain Dictionary

no code implementations3 Oct 2016 Chang-Hwan Son, Xiao-Ping Zhang

Based on this error map, both the sparse codes of rain and non-rain dictionaries are used jointly to represent the image structures of objects and avoid the edge artifacts in the non-rain regions.

Near-Infrared Image Dehazing Via Color Regularization

no code implementations1 Oct 2016 Chang-Hwan Son, Xiao-Ping Zhang

It is also shown that the proposed color regularization can remove the edge artifacts which arise from the use of the conventional dark prior model.
