Living organisms, in particular represented by humans, have various features that we should take account of. These include:
Analysis and modeling of these biological features not only study the scientific truth, but also contribute to the realization of these biological functions in engineering fields.
- the excellent perception of seeing, listening, and touching,
- Self organization (learning) for adapting to surrounding environment.
- integration of various sensory information
- active and purposive observation tightly related with motion/behavior,
- high level function such as speech generation, comprehension and problem solving.
Based on the physiological and psychological knowledges, we are engaged in modeling and simulation of visual and auditory processing.
- Research theme
- Model of Visual Organization
- Grouping of optical flows, and Generation of organized structure (form) based on Gestalt's laws.
- Model of Subjective Contour Generation
- Subjective contours are one of important illusions for understanding human visual information processing. An algorithm based on Gestalt's perceptual organization is proposed for generating subjective contours automatically from given figures.
- Transparency Perception and its Influence to other Cues for 3-D Reconstruction
- Perception of transparency is one of important cues for objects' overlapping. We are studying how to detect transparency in a image and identify a translucent object, and interactions between transparency perception and other depth cues.
Analysis of Binocular Gazing Positions
- We measure and analyze binocular gazing positions to investigate human visual information processing, especially determination of next gazing point and the process from retinal image capturing to spatial recognition.
