We describe the algorithm design and implementation of our submission for the EE368 final project, which involves detection of visual code markers in camera-phone images. We describe our approach and results, as well as the challenges faced during the development of our algorithm. For the reader’s interest, we also include a brief account of the algorithmic possibilities which we explored but d...

In the retina of trichromatic primates, chromatic information is encoded in an opponent fashion and transmitted to the lateral geniculate nucleus (LGN) and visual cortex via parallel pathways. Chromatic selectivities of neurons in the LGN form two separate clusters, corresponding to two classes of cone opponency. In the visual cortex, however, the chromatic selectivities are more distributed, w...

Introduction: This paper aims in addressing an obstacle in building the online community in computer graphics (CG) education that is achieving a critical mass of quality material. They propose a novel repository service introducing " live " graphics gems (Graphics Educational Material Source) to the material. The repository is given two services, server-side compiling and source-code versioning...

Self-localization as precondition for goal-oriented behavior is a fundamental property an autonomous mobile robot needs to be equipped with. This paper addresses the self-localization problem from a pragmatical point of view since it argues for using passive artificial landmarks in order to support mobile robot localization in indoor environments. The idea is to further improve already existing...

Cells in intermediate and deeper layers of the pigeon optic tectum respond best when a textured background pattern is moved in the opposite direction to a moving test spot. Complete inhibition occurs when the background moves in the same direction as the test stimulus. Most noteworthy is the invariance of this relationship over a wide range of test spot directions. These cells represent a highe...
