Cognitive Robotics: On the Semantic Knife-edge

Semantic-Based Image Retrial in the VQ Compressed Domain using Image Annotation Statistical Models

Semiautomatic Image Retrieval Using the High Level Semantic Labels

Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...

Derivation and validation of a sensitivity formula for knife-edge slit gamma camera: A theoretical and Monte Carlo simulation study

Introduction: Gamma cameras are proposed for online range verification and treatment monitoring in proton therapy.  An Analytical formula was derived and validated for sensitivity of a slit collimator based on the photon fluence concept. Methods: Fluence formulation was generalized for photons distribution function and solved for high-energy point sources. The...

From holistic scene understanding to semantic visual perception: A vision system for mobile robot

Semantic visual perception for knowledge acquisition plays an important role in human cognition, as well as in the many tasks expected to be performed by a cognitive robot. In this paper, we present a vision system designed for indoor mobile robotic systems. Inspired by recent studies on holistic scene understanding, we generate spatial information in the scene by considering plane estimation a...

Comparison of the Effectiveness of Semantic Cognitive Reconstruction Therapy and Self-Encouragement Therapy on Chronic Fatigue in People with Psychosomatic Skin

The purpose of this study was to the comparison of the effectiveness of semantic cognitive reconstruction therapy and self-encouragement therapy on chronic fatigue in people with psychosomatic skin. The research method was quasi-experimental with a pretest-posttest design with the control group. The statistical population of the study included people with psychosomatic skin who were referred to...
