The goal of surface reconstruction is to reconstruct a smooth surface while avoiding smoothing out discontinuities. In this paper, a new algorithm for surface reconstruction is proposed which can locate and identify discontinuities while reconstructing a smooth surface from a set of sparse and irregularly spaced depth measurements. This algorithm uses the wavelet transform technique to induce a multiresolution...
Classical DNA sequence compression algorithms consider only intra-sequence similarity, i.e., similar subsequences within the DNA sequence are found and encoded together. In this work, in addition to the intra-sequence similarity, we exploit the inter-sequence similarities in that similar subsequences are found within the DNA sequence as well as from other reference sequences. Hence, highly similar...
In this paper, multiscale directional filter bank (MDFB) is investigated for texture characterization and retrieval. First, the problem of aliasing in decimated bandpass images on directional decomposition is addressed. MDFB is then designed to suppress the aliasing effect as well as to minimize the reduction in frequency resolution. Second, an entropy-based measure on energy signatures is proposed...
