    Invariant Description and Retrieval of Planar Shapes Using Radon Composite Features
    Download  www.cv.fudan.edu.cn
    This paper proposes a novel feature-based invariant descriptor termed Radon composite features (RCFs) for planar shapes. Instead of analyzing shapes directly in the spatial domain,...

    Optimal Particle Filters for Tracking a Time-Varying Harmonic or Chirp Signal
    Download  www.telecom.tuc.gr
    We consider the problem of tracking the time-varying (TV) parameters of a harmonic or chirp signal using particle filtering (PF) tools. Similar to previous PF approaches to TV spec...

    Using the discrete wavelet frame transform to merge Landsat TM and SPOT panchromatic images
    Download  www.cs.ust.hk
    In this paper, we propose a pixel level image fusion algorithm for merging Landsat thematic mapper (TM) images and SPOT panchromatic images. The two source images are first decomp...

    Extension of phase correlation to subpixel registration
    Download  www.cs.ucf.edu
    In this paper, we have derived analytic expressions for the phase correlation of downsampled images. We have shown that for downsampled images the signal power in the phase correla...

    A computational strategy exploiting genetic algorithms to recover color surface reflectance functions
    Download  www.ivl.disco.unimib.it
    —Information about the spectral reflectance of a color surface is useful in many applications. Assuming that reflectance functions can be adequately approximated by a linear comb...
