You Only Look at Once for Real-time and Generic Multi-Task

1 code implementation2 Oct 2023 Jiayuan Wang, Q. M. Jonathan Wu, Ning Zhang

In this study, we present an adaptive, real-time, and lightweight multi-task model designed to concurrently address object detection, drivable area segmentation, and lane line segmentation tasks.

An Attentive-based Generative Model for Medical Image Synthesis

1 code implementation2 Jun 2023 Jiayuan Wang, Q. M. Jonathan Wu, Farhad Farhad

This study proposes an attention-based dual contrast generative model, called ADC-cycleGAN, which can synthesize medical images from unpaired data with multiple slices.

An Ensemble Semi-Supervised Adaptive Resonance Theory Model with Explanation Capability for Pattern Classification

no code implementations19 May 2023 Farhad Pourpanah, Chee Peng Lim, Ali Etemad, Q. M. Jonathan Wu

Firstly, SSL-ART adopts an unsupervised fuzzy ART network to create a number of prototype nodes using unlabeled samples.

Auto-Focus Contrastive Learning for Image Manipulation Detection

no code implementations20 Nov 2022 Wenyan Pan, Zhili Zhou, Guangcan Liu, Teng Huang, Hongyang Yan, Q. M. Jonathan Wu

However, we argue that those models achieve sub-optimal detection performance as it tends to: 1) distinguish the manipulation traces from a lot of noisy information within the entire image, and 2) ignore the trace relations among the pixels of each manipulated region and its surroundings.

DC-cycleGAN: Bidirectional CT-to-MR Synthesis from Unpaired Data

1 code implementation2 Nov 2022 Jiayuan Wang, Q. M. Jonathan Wu, Farhad Pourpanah

Specifically, a dual contrast loss is introduced into the discriminators to indirectly build constraints between real source and synthetic images by taking advantage of samples from the source domain as negative samples and enforce the synthetic images to fall far away from the source domain.

Projected Sliced Wasserstein Autoencoder-based Hyperspectral Images Anomaly Detection

no code implementations20 Dec 2021 Yurong Chen, HUI ZHANG, Yaonan Wang, Q. M. Jonathan Wu, Yimin Yang

In this case, the Wasserstein distance can be calculated with the closed-form, even the prior distribution is not Gaussian.

A Review of Generalized Zero-Shot Learning Methods

1 code implementation17 Nov 2020 Farhad Pourpanah, Moloud Abdar, Yuxuan Luo, Xinlei Zhou, Ran Wang, Chee Peng Lim, Xi-Zhao Wang, Q. M. Jonathan Wu

Generalized zero-shot learning (GZSL) aims to train a model for classifying data samples under the condition that some output classes are unknown during supervised learning.

High Frequency Content based Stimulus for Perceptual Sharpness Assessment in Natural Images

no code implementations17 Dec 2014 Ashirbani Saha, Q. M. Jonathan Wu

A blind approach to evaluate the perceptual sharpness present in a natural image is proposed.

Full-reference image quality assessment by combining global and local distortion measures

no code implementations17 Dec 2014 Ashirbani Saha, Q. M. Jonathan Wu

Therefore, we hypothesize that the resulting objective score for an image can be derived from the combination of local and global distortion measures calculated from the reference and test images.

Pulling back error to the hidden-node parameter technology: Single-hidden-layer feedforward network without output weight

no code implementations6 May 2014 Yimin Yang, Q. M. Jonathan Wu, Guang-Bin Huang, Yaonan Wang

SLFNs are universal approximators when at least the parameters of the networks including hidden-node parameter and output weight are exist.
