Hybrid processor to compute invariant moments for pattern recognition.
The use of invariant moments" 2 for pattern recognition and scene matching has received considerable attention.1-8 The majority of this work has utilized digital processors. 3 -6 In this Letter, we describe a hybrid optical-digital system that can compute all the invariant moments of a 2-D image in parallel by spatial convolution. This is an extension of earlier work7 that required separate mas...
متن کاملOrthogonal Fourier-Mellin moments for invariant pattern recognition
Received July 7, 1993; revised manuscript received November 22, 1993; accepted December 14, 1993 We propose orthogonal Fourier-Mellin moments, which are more suitable than Zernike moments, for scaleand rotation-invariant pattern recognition. The new orthogonal radial polynomials have more zeros than do the Zernike radial polynomials in the region of small radial distance. The orthogonal Fourier...

Many scienti c applications that run on today s multiprocessors such as weather forecast ing and seismic analysis are bottlenecked by their le I O needs Even if the multiprocessor is con gured with su cient I O hardware the le system software often fails to provide the available bandwidth to the application Although libraries and enhanced le system interfaces can make a signi cant improvement w...
متن کاملA filter bank method to construct rotationally invariant moments for pattern recognition
We propose multiresolution filter bank techniques to construct rotationally invariant moments. The multiresolution pyramid motivates a simple but efficient feature selection procedure based on a combination of a pruning algorithm, a new version of the Apriori mining techniques and the partially supervised fuzzy C-mean clustering. The recognition accuracy of the proposed techniques has been test...
متن کاملApplication of semi-analytic method to compute the moments for solution of logistic model
The population growth, is increase in the number of individuals in population and it depends on some random environment effects. There are several different mathematical models for population growth. These models are suitable tool to predict future population growth. One of these models is logistic model. In this paper, by using Feynman-Kac formula, the Adomian decomposition method is applied to ...
