      Genetic algorithm guided selection: variable selection and subset
      selection A novel genetic algorithm guided selection method, GAS, has been
      described. The method utilizes a simple encoding scheme which can
      represent both compounds and variables used to construct a QSAR/QSPR
      model. A genetic algorithm is then utilized to simultaneously optimize the
      encoded variables that include both descriptors and compound subsets. The
      GAS method generates multiple models each applying to a subset of the
      compounds. Typically the subsets represent clusters with different
      chemotypes. Also a procedure based on molecular similarity is presented to
      determine which model should be applied to a given test set compound. The
      variable selection method implemented in GAS has been tested and compared
      using the Selwood data set -LRB- n = 31 compounds; nu = 53 descriptors
      -RRB-. The results showed that the method is comparable to other published
      methods. The subset selection method implemented in GAS has been first
      tested using an artificial data set -LRB- n = 100 points; nu = 1
      descriptor -RRB- to examine its ability to subset data points and second
      applied to analyze the XLOGP data set -LRB- n = 1831 compounds; nu = 126
      descriptors -RRB-. The method is able to correctly identify artificial
      data points belonging to various subsets. The analysis of the XLOGP data
      set shows that the subset selection method can be useful in improving a
      QSAR/QSPR model when the variable selection method fails

      Presentation media, information complexity, and learning outcomes
      Multimedia computing provides a variety of information presentation
      modality combinations. Educators have observed that visuals enhance
      learning which suggests that multimedia presentations should be superior
      to text-only and text with static pictures in facilitating optimal human
      information processing and, therefore, comprehension. The article reports
      the findings from a 3 -LRB- text-only, overhead slides, and multimedia
      presentation -RRB- * 2 -LRB- high and low information complexity -RRB-
      factorial experiment. Subjects read a text script, viewed an acetate
      overhead slide presentation, or viewed a multimedia presentation depicting
      the greenhouse effect -LRB- low complexity -RRB- or photocopier operation
      -LRB- high complexity -RRB-. Multimedia was superior to text-only and
      overhead slides for comprehension. Information complexity diminished
      comprehension and perceived presentation quality. Multimedia was able to
      reduce the negative impact of information complexity on comprehension and
      increase the extent of sustained attention to the presentation. These
      findings suggest that multimedia presentations invoke the use of both the
      verbal and visual working memory channels resulting in a reduction of the
      cognitive load imposed by increased information complexity. Moreover,
      multimedia superiority in facilitating comprehension goes beyond its
      ability to increase sustained attention; the quality and effectiveness of
      information processing attained -LRB- i.e., use of verbal and visual
      working memory -RRB- is also significant

      Adaptive filtering for noise reduction in hue saturation intensity color
      space Even though the hue saturation intensity -LRB- HSI -RRB- color model
      has been widely used in color image processing and analysis, the
      conversion formulas from the RGB color model to HSI are nonlinear and
      complicated in comparison with the conversion formulas of other color
      models. When an RGB image is degraded by random Gaussian noise, this
      nonlinearity leads to a nonuniform noise distribution in HSI, making
      accurate image analysis more difficult. We have analyzed the noise
      characteristics of the HSI color model and developed an adaptive spatial
      filtering method to reduce the magnitude of noise and the nonuniformity of
      noise variance in the HSI color space. With this adaptive filtering
      method, the filter kernel for each pixel is dynamically adjusted,
      depending on the values of intensity and saturation. In our experiments we
      have filtered the saturation and hue components and generated edge maps
      from color gradients. We have found that by using the adaptive filtering
      method, the minimum error rate in edge detection improves by approximately
      15%

      Restoration of broadband imagery steered with a liquid-crystal optical
      phased array In many imaging applications, it is highly desirable to
      replace mechanical beam-steering components -LRB- i.e., mirrors and
      gimbals -RRB- with a nonmechanical device. One such device is a nematic
      liquid crystal optical phased array -LRB- LCOPA -RRB-. An LCOPA can
      implement a blazed phase grating to steer the incident light. However,
      when a phase grating is used in a broadband imaging system, two adverse
      effects can occur. First, dispersion will cause different incident
      wavelengths arriving at the same angle to be steered to different output
      angles, causing chromatic aberrations in the image plane. Second, the
      device will steer energy not only to the first diffraction order, but to
      others as well. This multiple-order effect results in multiple copies of
      the scene appearing in the image plane. We describe a digital image
      restoration technique designed to overcome these degradations. The
      proposed postprocessing technique is based on a Wiener deconvolution
      filter. The technique, however, is applicable only to scenes containing
      objects with approximately constant reflectivities over the spectral
      region of interest. Experimental results are presented to demonstrate the
      effectiveness of this technique

      A comparison of computational color constancy Algorithms. II. Experiments
      with image data For pt.I see ibid., vol. 11, no. 9, p.972-84 -LRB- 2002
      -RRB-. We test a number of the leading computational color constancy
      algorithms using a comprehensive set of images. These were of 33 different
      scenes under 11 different sources representative of common illumination
      conditions. The algorithms studied include two gray world methods, a
      version of the Retinex method, several variants of Forsyth's -LRB- 1990
      -RRB- gamut-mapping method, Cardei et al.'s -LRB- 2000 -RRB- neural net
      method, and Finlayson et al.'s color by correlation method -LRB- Finlayson
      et al. 1997, 2001; Hubel and Finlayson 2000 -RRB-. We discuss a number of
      issues in applying color constancy ideas to image data, and study in depth
      the effect of different preprocessing strategies. We compare the
      performance of the algorithms on image data with their performance on
      synthesized data. All data used for this study are available online at
      http://www.cs.sfu.ca/~color/data, and implementations for most of the
      algorithms are also available -LRB- http://www.cs.sfu.ca/~color/code
      -RRB-. Experiments with synthesized data -LRB- part one of this paper
      -RRB- suggested that the methods which emphasize the use of the input data
      statistics, specifically color by correlation and the neural net
      algorithm, are potentially the most effective at estimating the
      chromaticity of the scene illuminant. Unfortunately, we were unable to
      realize comparable performance on real images. Here exploiting pixel
      intensity proved to be more beneficial than exploiting the details of
      image chromaticity statistics, and the three-dimensional -LRB- 3-D -RRB-
      gamut-mapping algorithms gave the best performance
