We propose a new method for rectifying a geometrical distortion in the elemental image set and extracting an accurate lens lattice lines by projective image transformation. The information of distortion in the acquired elemental image set is found by Hough transform algorithm. With this initial information of distortions, the acquired elemental image set is rectified automatically without the p...

Image compression is concerned with reducing the amount of data needed to represent an image. Efficient image representation is achieved by exploiting the statistical and psychovisual redundancies of an image. This reported focusses on the main principles of information theory, which provides a framework for efficient signal coding from a statistical perspective. Two of the fundamental theories...

The appearance of moving features in the field-of-view (FoV) of the camera may substantially change due to different camera poses. Typical solutions for tracking image points involve the assumption of an image motion model and the estimation of the motion parameters using image alignment techniques. While for conventional cameras this suffices, the radial distortion that arises in cameras with ...

Abstract Mechanical metamaterials possess unusual mechanical properties that cannot be found in nature. Auxetic have negative Poisson's ratios and tend to expand a direction perpendicular the axial extension direction. When ratio of display circuit board is forced −1 by adopting an auxetic metamaterial, can stretchable without image distortion, this called meta‐display study. The critical obsta...

PURPOSE Body image incorporates cognitive and affective components as well as behaviors related to own body perception. This study evaluated the occurrence of body image distortion and its correlates in Korean adolescents. METHODS In a school-based cross-sectional survey, a total of 2,117 adolescents were recruited. They filled out self-completing questionnaires on body image distortion, eati...
