The complexity of the algorithm is O (K 3 N), where K is the number of image features kept after the photometric test and N is the number of object points.
WebThe volatile compounds in three Lang baijiu ("Honghualangshi, Y1", "Langjiulangge, Y2", and "Laolangjiu, Y3") were identified by gas chromatography-olfactometry (GC-O), gas chromatography-mass spectrometry (GC-MS), flame photometric detection (FPD), and nitrogen phosphorus detector (NPD) with the aid of stir bar sorptive extraction (SBSE). WebA chromatography detector is a device used in gas chromatography (GC) or liquid chromatography (LC) to detect components of the mixture being eluted off the chromatography column. There are two general types of detectors: destructive and non-destructive. The destructive detectors perform continuous transformation of the column …
