Active vision brings important advantages for physically embodied artificial agents interacting with their environment. Gaze control is one of the important issues in active vision. In this paper, we address one subproblem of gaze control, namely, gaze stabilization, which appears when visually tracking a moving object is required. One approach to tackle this is by solving a motion estimation p...

Effective object motion estimation is significant to improve the performance of soccer robots in RoboCup Middle Size League. In this paper, a hybrid vision system is constructed by combining omnidirectional vision and stereo vision for ball recognition and motion estimation in three-dimensional (3D) space. When the ball is located on the ground field, a novel algorithm based on RANSAC and Kalma...

In a first-order reversed-phi motion stimulus (Anstis, 1970), the black-white contrast of successive frames is reversed, and the direction of apparent motion may, under some conditions, appear to be reversed. It is demonstrated here that, for many classes of stimuli, this reversal is a mathematical property of the stimuli themselves, and the real problem is in perceiving forward motion, which i...

Humanoid robots have the similar appearance to human being with a head, two arms and two legs, and has some intelligent abilities as human being, such as object recognition, tracking, voice identification, obstacle avoidance, and so on. Since they try to simulate the human structure and behavior and they are autonomous systems, most of the times humanoid robots are more complex than other kinds...

We described a real-time 3D computer vision system called MIMIC(Motion Interface & Motion Information Capture system) that can capture and save motion of an actor. This system analyzes input images from vision sensors and searches feature information like a head, hands, and feet. Moreover, this estimates intermediated joints as an elbow and knee using feature information and makes 3D human mode...

ÐMotion detection can play an important role in many vision tasks. Yet image motion can arise from auninterestingo events as well as interesting ones. In this paper, salient motion is defined as motion that is likely to result from a typical surveillance target (e.g., a person or vehicle traveling with a sense of direction through a scene) as opposed to other distracting motions (e.g., the scin...

This paper presents a new constraint, ie., projective transformation constraint, to solve the di cult problem of motion stereo correspondence in the context where the motion is dominated by rotation (for instance, 10 degrees of rotation with 1 cm of translation). Our observation here is that two consecutive images can be related to each other by a 2D projective transformation. Its coe cients ar...

To improve the environment perception ability of wheeled mobile robots (WMRs), visual behavior mechanism negative-correlation motion chameleons is introduced into binocular vision system WMRs, and a shifty-behavior-based model with chameleon-inspired active for WMRs established, where vision–motor coordination achieved. First, target search sub-model built. The relationship between rotation ang...

In this paper, we present an extension to the real-time motion template research for computer vision as previously developed in (Davis 1997). The underlying representation is a Motion History Image (MHI) that temporally layers consecutive image silhouettes (or motion properties) of a moving person into a single template form. Originally a global, label-based method was used for recognition. In ...
