    In this study a new algorithm `adaptive bandwidth mode detection` (ABMD) algorithm has been developed to recover the correct density function without the need to either specify the correct number of Gaussians in the model or the correct bandwidth. The ABMD is employed in modelling visual features in applications such as image segmentation and real-time visual tracking. A simple type of model for t... View full abstract»

  • Comparison of diverse approaches for synthetic aperture radar images pixel fusion under different precision registration

    All kinds of approaches have been proposed to implement the pixel fusion for remote-sensing images that must be strictly registered in advance. Errors introduced by finite precision registration would influence the performance of fusion process. Moreover, it is not easy to achieve high precision registration on synthetic aperture radar (SAR) images. Thus it is significative to evaluate the perform... View full abstract»

    Text information contains important clues for video analysis, indexing and retrieval. Effective and efficient text extraction has been a challenging and significant topic. Focusing on this issue, this study proposes a video text extraction scheme using key text points (KTPs). A KTP is defined as the point that has strong textural structure in multi-directions simultaneously. First, a KTP can be ac... View full abstract»

  • Hybrid wavelet denoising procedure of discontinuous surfaces

    Publication Year: 2011, Page(s):684 - 692
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1127 KB)

    In this study, the authors propose a method for recovering a two-dimensional surface (image) from noisy observations containing significant jumps and discontinuities. The proposed procedure, termed as the segmented polynomial wavelet regression (SPWR) algorithm, combines wavelet regression with polynomial extrapolation and segmentation procedures. The bias that might occur on the discontinuous sur... View full abstract»

  • Directional lifting wavelet and universal trellis-coded quantisation-based image coding algorithm and objective quality evaluation

    Publication Year: 2011, Page(s):693 - 702

    In this study, an image coding algorithm based on directional lifting wavelet transform (DLWT) and universal trellis-coded quantisation (UTCQ) is presented, and the coding performance is evaluated with three objective image quality metrics. Compared to the discrete wavelet transform, DLWT performing prediction and update along the direction of the local region can provide an efficient representati... View full abstract»
