Detekció
Detekció is the process of identifying the presence or absence of a target signal, event, or condition in data. In Hungarian usage it covers a wide range of disciplines, from engineering and science to everyday monitoring. A detector or detection method typically transforms raw measurements into a decision about whether the target is present, which may then be followed by classification or localization. Detection is distinct from recognition or identification, which adds a level of categorization.
In statistics and signal processing, detekció is analyzed with detection theory. Key concepts include the detection
Applications include medical imaging and screening (tumor or lesion detection), cybersecurity (intrusion detection systems), environmental sensing
Common workflow: data acquisition by sensors, preprocessing, feature extraction, and a decision rule. Challenges include noise,
