Properties of approximate Parks-McClellan filters

It has been observed empirically that each coe cient in a Parks-McClellan lter converges to a steady state value as the lter length increases. This suggests the possibility of obtaining lters that are near optimal while "re-using" lter coe cients from shorter lters in the design of longer lters. In the context of approximate processing this then allows a ltering operation to be done in stages. ...

3-D depth migration via McClellan transformations

Three-dimensional seismic wavefields may be extrapolated in depth, one frequency at a time by two-dimensional convolution with a circularly symmetric, frequencyand velocity-dependent filter. This depth extrapolation, performed for each frequency independently, lies at the heart of 3-D finite-difference depth migration. The computational efficiency of 3-D depth migration depends directly on the ...

Nominated Texture Based Cervical Cancer Classification

Accurate classification of Pap smear images becomes the challenging task in medical image processing. This can be improved in two ways. One way is by selecting suitable well defined specific features and the other is by selecting the best classifier. This paper presents a nominated texture based cervical cancer (NTCC) classification system which classifies the Pap smear images into any one of t...
