Portable Smartphone Platform Based on a Single Dual-Emissive Ratiometric Fluorescent Probe for Visual Detection of Isopropanol in Exhaled Breath.

Analytical Chemistry, 2021
The components in the exhaled breath have been confirmed to be related to certain diseases, especially studies have shown that isopropanol (IPA) might be closely associated with illnesses such as lung cancer, and are considered as a biomarker. Herein, we

A portable test strip based on fluorescent europium-based metal-organic framework for rapid and visual detection of tetracycline in food samples.

Food Chemistry, 2021
Residual tetracycline (TC) in animal food caused by abuse of antibiotics leads to many chronic diseases in the human body. The development of a simple and on-site visualization method for TC detection is need of the hour.

An ingenious turn-on ratiometric fluorescence sensor for sensitive and visual detection of tetracyclines.

Food Chemistry, 2022
To achieve facile and rapid detection of tetracyclines (TCs), herein, we fabricated an ingenious turn-on ratiometric fluorescence sensor (Ru@ZIF-8) based on embedding red-emitting Ru(bpy)32+ into zeolitic imidazolate framework-8 (ZIF-8).

Face detection for visual surveillance

12th International Conference on Image Analysis and Processing, 2003.Proceedings., 2004
In this paper, a real-time face detection system for color image sequences is presented. The system applies three different face detection methods and integrates the obtained results to achieve a greater location accuracy. The first method localizes the human head through outline analysis, focusing the attention of the system on a small image area. The

Visual Relation of Interest Detection

Proceedings of the 28th ACM International Conference on Multimedia, 2020
In this paper, we propose a novel Visual Relation of Interest Detection (VROID) task, which aims to detect visual relations that are important for conveying the main content of an image, motivated from the intuition that not all correctly detected relations are really "interesting" in semantics and only a fraction of them really make sense for ...
