Evaluation of Detection Probability for Flaw by Multiple Modalities
Masao NAKAGAWA and Hidetoshi NAKAYASU
Abstract:In order to evaluate the probability of detecting the flaw in the materials, it is studied how to measure and identify the cognitive capability of the human being with multiple modalities. Procedures for measurement of psychometric functions of a single attribute and joint probability of dual attributes in the inspection image data are proposed by the experiment of paired comparison under constant stimuli. The validity of the proposal methods was also verified by the examples of the experiments of single and dual attributes from the inspection sample data of mat FRP panel. From the results of these examples, the differences of the detection probabilities were illustrated by the features in single and multiple modalities such as the psychometric curves for each attributes, correlation matrix among attributes and so on. Key Words:Multiple modalities, Stimulus threshold, Detection probability, Psychometric function, Paired comparison
