Textures are replications, symmetries and combinations of various basic patterns, usually with some random variation one of the gray-level statistics. This article proposes a new approach to Segment texture images. The proposed approach proceeds in 2 stages. First, in this method, local texture information of a pixel is obtained by fuzzy texture unit and global texture information of an image i...

In the range of 83 500-89 200 cm ‘, the photoionization spectrum of HI is strongly influenced by autoionization of Rydberg series converging to the higher lying 2B,,2 component of the spin-orbit split ‘H ionic ground state. The photoelectron yield spectrum, exhibiting the various autoionization processes, has been measured on a rotationally cooled sample ( T,,, 13 K), with a spectral resolution...

This paper presents a new method for robust voiced/unvoiced segment (V/UV) classification and accurate fundamental frequency ( ) estimation in a noisy environment. For this purpose, we introduce the degree of dominance and dominance spectrum that are defined by instantaneous frequency. The degree of dominance allows us to evaluate the magnitude of individual harmonic components of speech signal...

We present a novel extended-focus optical coherence microscope (OCM) attaining 0.7 μm axial and 0.4 μm lateral resolution maintained over a depth of 40 μm, while preserving the advantages of Fourier domain OCM. Our system uses an ultra-broad spectrum from a supercontinuum laser source. As the spectrum spans from near-infrared to visible wavelengths (240 nm in bandwidth), we call the system visO...

This paper proposes a new speech modification algorithm based on a vocoder framework to synthesize high quality speech. Its innovation is in preserving the fine structure of the magnitude spectrum. A key point is the use of a “compensatory gaussian window” to extract moderate F0 harmonics structures in the magnitude spectrum. The other key point is, starting from the magnitude spectrum, generat...

Interpretation of x-ray absorption near-edge structure (XANES) experiments is often done via analyzing the role of particular atoms in the formation of specific peaks in the calculated spectrum. Typically, this is achieved by calculating the spectrum for a series of trial structures where various atoms are moved and/or removed. A more quantitative approach is presented here, based on comparing ...

We present a 5–37 μm infrared spectrum obtained with the Spitzer Space Telescope toward the southeastern lobe of the young protostellar outflow HH211. The spectrum shows an extraordinary sequence of OH emission lines arising in highly excited rotational levels up to an energy E/ k ≈ 28200K above the ground level. This is, to our knowledge, by far the highest rotational excitation of OH observed...
