... was conducted, and a total of 38 reference papers were studied. This review included gas chromatography-mass spectrometry (GC-MS), electronic nose (E-nose) technologies, nanomaterial-based sensors, signal processing, feature extraction and artificial intelligence ( AI ). Findings are analyzed to determine...

..., comprising an instrumentation amplifier, a Sallen–Key band-pass filter and a noninverting amplifier, is designed and tested on a portable printed circuit board. The purpose of this paper is to perform feature extraction and data segmentation for effective analysis and processing of the recorded sEMG signals...

...Shenlong Wang; Kaixin Han; Jiafeng Jin Purpose In the past few decades, the content-based image retrieval (CBIR), which focuses on the exploration of image feature extraction methods, has been widely investigated. The term of feature extraction is used in two cases: application-based feature...

...Jia Yan; Shukai Duan; Tingwen Huang; Lidan Wang Purpose – The purpose of this paper is to improve the performance of E-nose in the detection of wound infection. Feature extraction and selection methods have a strong impact on the performance of pattern classification of electronic nose (E-nose...
