Multi-target and multi-stage liver lesion segmentation and detection in multi-phase computed tomography scans

no code implementations17 Apr 2024 Abdullah F. Al-Battal, Soan T. M. Duong, Van Ha Tang, Quang Duc Tran, Steven Q. H. Truong, Chien Phan, Truong Q. Nguyen, Cheolhong An

Although this approach utilizes information from all the phases and outperform single-phase segmentation networks, we demonstrate that their performance is not optimal and can be further improved by incorporating the learning from models trained on each single-phase individually.

In Defense of Scene Graphs for Image Captioning

1 code implementation ICCV 2021 Kien Nguyen, Subarna Tripathi, Bang Du, Tanaya Guha, Truong Q. Nguyen

Several studies have noted that the naive use of scene graphs from a black-box scene graph generator harms image captioning performance and that scene graph-based captioning models have to incur the overhead of explicit use of image features to generate decent captions.

DPW-SDNet: Dual Pixel-Wavelet Domain Deep CNNs for Soft Decoding of JPEG-Compressed Images

no code implementations27 May 2018 Honggang Chen, Xiaohai He, Linbo Qing, Shuhua Xiong, Truong Q. Nguyen

The pixel domain deep network takes the four downsampled versions of the compressed image to form a 4-channel input and outputs a pixel domain prediction, while the wavelet domain deep network uses the 1-level discrete wavelet transformation (DWT) coefficients to form a 4-channel input to produce a DWT domain prediction.
