The phrase "a database of features" is correct and usable in written English.
It can be used when referring to a structured collection of information that describes various characteristics or functionalities of a product, system, or service.
Example: "The software includes a comprehensive database of features that allows users to customize their experience."
Alternatives: "a repository of features" or "a catalog of features".
A major issue that we observed is the increased amount of computational time due to the matching with a database of features.
A database of features of interest taken from many images (often more than 10,000) is prestored in the camera and algorithms are used to determine what is being captured and accordingly determine the optimal exposure settings.
We then extend the pairwise approach by working with a database of features (indicated with FPdb) which collects the feature sets associated to all the previously aligned range images, so that the feature set associated to the current range image FP k is matched to the database FPdb. Figure 8 illustrates the block diagram of the multi-view alignment pipeline we propose.
As a whole, this background of knowledge can form a database of features that can be employed in the robotics modelling of encoding and decoding expressive sensory cues pertaining to facial expressions (e.g. Wimmer et al. [ 38]), motion cues (e.g. Castellano et al. [ 4]), vocal cues (e.g. Vogt et al. [ 30]) and physiological measures (e.g. Barber et al. [ 2]).
A database of feature vectors is generated for all possible grasps for each object in the feature space.
Genotyping of microorganisms typically relies on comparison of genomic features (e.g., fragment size, repeats, single-nucleotide polymorphisms [SNPs]) between strains and/or against a database of feature profiles (e.g., PulseNET and mlst.net) for a population of the microbe of interest.
Each of them provides a database of genomic features collected from multiple data sources, and a procedure for users to query selected features around their genetic variants.
It also aims to provide institutions with a database of geological features that may interact with buildings and infrastructures, including active and inactive faults, shallow landslides, deep gravitational slides, and karst collapse.
Topologically Integrated Geographic Encoding and Referencing data [ U.S. Census Bureau (USCB) 2005], a database of geographic features (e.g., roads and rivers).
It scoured the landscape and built a huge database of features and similarities — which can be quickly queried and the results returned immediately (the neural network isn't doing any "thinking" when you click on a feature — its work is done for this dataset).
In that sense, its images can be matched with high reliability against a large database of features from many images.
