A Fraser illusion without local cues?
In the well-known Fraser illusion, a line composed of tilted elements itself appears tilted. The standard explanation of this illusion has been that the global orientation of the line is in some way influenced by the local orientation of the elements. The illusion was recreated using a texture composed of collinear Gabor stimuli, which were vertical. There was no local tilt. The illusory tilt w...
متن کاملThe neural signature of the Fraser illusion: an explorative EEG study on Fraser-like displays
We studied neural correlates accompanying the Fraser spiral illusion. The Fraser spiral illusion consists of twisted cords superimposed on a patchwork background arranged in concentric circles, which is typically perceived as a spiral. We tested four displays: the Fraser spiral illusion and three variants derived from it by orthogonally combining featural properties. In our stimuli, the shape o...
متن کاملA New Component of the Fraser Complex
In embryos, the Fraser complex (FC) mediates epithelial-connective tissue interactions. Loss of expression of FC components leads to Fraser syndrome (FS), in which cohesion of epithelial tissues and stroma is perturbed. Using zebrafish, Richardson et al. (this issue) identified the protein AMACO in the FC. We discuss the utility of zebrafish in determining FC functions and identifying FS targets.
متن کاملRepresentation of Complex Animated Figures
Humans and animals are extraordinarily complex mechanical systems whose articulated movements are difficult to represent, control, and display. This paper describes a method for representing articulated figures as skeletons, for use with a skeleton animation system currently under development. Our implementation includes a translator for mapping structured descriptions of skeletons into an inte...
متن کاملHierarchical Kinematic Behaviors for Complex Articulated Figures
The hierarchical control decomposition provided by inverse kinematics is seldom used in the field of Computer Animation. In this chapter we first review the properties and limitations of inverse kinematics compared to other techniques dedicated to the motion control of complex articulated figures. Then, beyond the sole pseudo-inverse solution, we examine the homogeneous solution allowing the pa...
