Abstract: This image processing device is provided with an acquisition unit (3), a construction unit (4), and an extraction unit (5). The acquisition unit (3) acquires: a pseudo-output that simulates, as an actual output, a perspective image in which respective luminances derived from a plurality of objects including a target object and a non-target object other than the target object are superimposed; and a pseudo-state quantity that simulates, as an actual state quantity, a superimposed pattern in which the luminance derived from the target object and the luminance derived from the non-target object are superimposed on each other. The construction unit (4) constructs, on the basis of the pseudo-output and the pseudo-state quantity acquired by the acquisition unit (3), a stochastic state space model in which an observable output is stochastically generated from an unobservable state quantity that transitions stochastically. The extraction unit (5) estimates a stochastically probable maximum likelihood estimator of the actual state quantity on the basis of the stochastic state space model constructed by the construction unit (4) and the perspective image, and extracts, from this maximum likelihood estimator, the luminance derived from the target object as a target object.

Title: Visual approach–based aptitude testing system

Filed: 2019-06-21
Abstract: [Problem] To obtain a multifaceted understanding of an individual's mental make-up through visual information, and to accurately and objectively ascertain the tendencies of an examinee, such as the examinee's occupational aptitude. [Solution] The subconscious mind of an examinee is revealed by the application condition of a plurality of icons that are applied to a check sheet in which a plurality of areas are formed in a frameless test area and which comprises graphic figures having no particular meaning in and of themselves. Through the information the examinee obtains visually, i.e. the application condition of the icons upon the check sheet, the inner, subconscious mind of the examinee is expressed, via a picture, in a manner that is visual and specific. The amygdala, which controls emotions, reacts to visual information 100 ms faster than the neocortex. Accordingly, the present invention makes it possible to obtain an understanding of the subconscious mind at the unconscious level prior to conscious control, and thus the aptitude of the examinee is revealed. The icons are recognized as graphic figures, and therefore affect the subconscious in the frontal lobe without stimulating emotional systems.
