A Neuromorphic Multi-chip Model of a Disparity Selective Complex Cell
The relative depth of objects causes small shifts in the left and right retinal positions of these objects, called binocular disparity. Here, we describe a neuromorphic implementa...

On the Huffman and Alphabetic Tree Problem with General Cost Functions
We study a wide generalization of two classical problems, the Huffman Tree and Alphabetic Tree Problem. We assume that the cost caused by the ith leaf is fi(di), where di is its d...

A phase-based stereo vision system-on-a-chip
A simple and fast technique for depth estimation based on phase measurement has been adopted for the implementation of a real-time stereo system with sub-pixel resolution on an FP...

Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps
This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that ty...
