In this paper, we propose a novel unsupervised algorithm for the segmentation of salient regions in color images. There are two phases in this algorithm. In the first phase, we use nonparametric density estimation to extract dominant colors in an image, which are then used for the quantization of the image. The label map of the quantized image forms initial(More)
Bizarre parosteal osteochondromatous proliferation (BPOP) is a benign disorder within a spectrum of reactive proliferative processes of tubular bones, particularly the phalanges of the fingers or toes. The cause is unknown, and it is difficult to distinguish BPOP from a bone or soft tissue tumor. The radiographic and magnetic resonance imaging(More)
PURPOSE Quantitative breast density is known as a strong risk factor associated with the development of breast cancer. Measurement of breast density based on three-dimensional breast MRI may provide very useful information. One important step for quantitative analysis of breast density on MRI is the correction of field inhomogeneity to allow an accurate(More)
This study synthesized a TiO2/carbon nanotubes (CNTs) composite via the sol-gel method. The surface characteristics of the TiO2/CNTs composite were determined by X-ray diffraction, transmission electron microscopy, specific surface area analyser, ultraviolent (UV)-vis spectroscopy, X-ray photoelectron spectroscopy and Raman spectrometer. The photocatalytic(More)
Long term evolution-advanced (LTE-A) supports high-speed communications for cellular systems. It allows different types of base stations to form a heterogeneous network to provide service. However, signal interference between a macrocell and its picocells is inevitable. Thus, LTE-A adopts enhanced intercell interference coordination (eICIC) to conquer the(More)
Nanoporous silica films were prepared through the templating of amphiphilic block copolymer, poly(styrene-2-vinyl pyridine) (PS-b-P2VP), and monodispersed colloidal silica nanoparticles. The experimental and theoretical studies suggested that the intermolecular hydrogen bonding existes between the colloidal silica nanoparticles and PS-b-P2VP. The effects of(More)
