Abstract

This paper presents a performance analysis and comparison of several pre-processing  methods  used  in  a  hand  gesture  recognition  system.  The  preprocessing methods are based on the combinations ofseveral image processing operations,  namely  edge  detection,  low  pass  filtering,  histogram  equalization, thresholding and desaturation. The hand gesture recognition system is designed to classify an input image into one of six possibleclasses. The input images are taken with various background conditions. Our experiments showed that the best result is achieved when the pre-processing method consists of only a desaturation operation, achieving a classification accuracy of up to 83.15%.

Abstract

This  paper  investigates the  performance  of  wavelet-based multiresolution  motion  estimation (MRME)  for  inbetweening  in  old  animated films  using  three different  MRME  schemes.  The  three  schemes  are:  coarse-to fine with a wavelet-based MRME, one of Zhang's MRMEs, and an MRME in the spatial domain.  In order to make a performance comparison of these MRME  schemes,  two  video  sequences were  used  for  a  simulation.  The  experimental results  show  that  the  coarse-to-fine  method  performed  better  than  Zhang's  MRME  and  the  MRME in the spatial domain. The evaluation results  on block size 9x9 indicate that the coarse-to-fine method had an average peak signal-to-noise ratio (PSNR) of  23.48 dB for the first sequence and 29.84 for the second sequence.

Abstract

If a communication network N with n stations has every station linked with  at  least [n/2] other  stations,  then the  edge-connectivity  of  N  equals  its minimum  degree.  Also, in  general,  this  limitation  is  stated  to  be  the  best possibility,  as  was  proved  by  Chartrand  in  1966.  A  more developed  notion  of edge-connectivity  is  introduced, which  is  called  k-component  order  edge connectivity. It  is the minimum number of edges required to be removed so that the order of each disconnected component is less than k.

Abstract

In  order  to  assist  researchers  in  addressing  time  constraint  and  low relevance  in  using  scientific  articles,  an  automatic  tailored  multi-paper summarization  (TMPS)  is  proposed.  In  this  paper,  we  extend  Teufel's  tailored summary  to  deal  with  multi-papers  and  more  flexible  representation  of  user information needs. Our TMPS extracts Rhetorical Document Profile (RDP) from each paper and  presents a summary based on user information needs.  Building Plan  Language  (BPLAN)  is  introduced  as  a  formalization  of  Teufel's  building plan  and  used  to  represent summary  specification,  which  is  more  flexible representation user information needs. Surface repair is embedded within the BPLAN  for  improving  the  readability  of  extractive summary.  Our  experiment shows that the average performance of RDP extraction module is 94.46%, which promises  high  quality  of  extracts  for  summary  composition.  Generality evaluation  shows  that  our  BPLAN  is  flexible  enough  in  composing  various forms  of summary.  Subjective  evaluation  provides evidence that  surface repair operators can improve the resulting summary readability.
