A Correlation Chip for Stereo Vision
نویسندگان
چکیده
This paper gives an example of how computer vision algorithms can be reformulated to exploit correlation based hardware without compromising the underlying principles of the algorithm. The work shows results of the "stretch-correlation" algorithm for calibrated stereo depth estimation and goes on to discuss the development of a convolution chip for implementing this algorithm. The motivation for the chip and its applicability to other computer vision algorithms is also discussed.

متن کاملAn Analog VLSI Neural Network for Phase-based Machine Vision
We describe the design, fabrication and test results of an analog CMOS VLSI neural network prototype chip intended for phase-based machine vision algorithms. The chip implements an image filtering operation similar to Gabor-filtering. Because a Gabor filter's output is complex valued, it can be used to define a phase at every pixel in an image. This phase can be used in robust algorithms for di...
متن کاملA Platform-Based SoC Design for Real-Time Stereo Vision
A stereo vision is able to build threedimensional maps of its environment. It can provide much more complete information than a 2D image based vision but has to process, at least, that much more data. In the past decade, real-time stereo has become a reality. Some solutions are based on reconfigurable hardware and others rely on specialized hardware. However, they are designed for their own spe...
متن کاملAn Evaluation of Correlation based Stereo Matching Algorithms by Considering Various Parameters
Stereo vision is one of the most active research areas in computer vision for an accurate estimation of disparity. Many researchers have been undergone past from many decades to find an accurate disparity, but still it is not an easy task to choose an appropriate algorithm for the required real time application. To overcome from this problem we introduce an objective that evaluates a set of six...
