For the wrapped phase map with regional abnormal fringes, a new phase unwrapping algorithm that combines the image-inpainting theory and the quality-guided phase unwrapping algorithm is proposed. First, by applying a threshold to the modulation map, the valid region (i.e., the interference region) is divided into the doubtful region (called the target region during the inpainting period) and th...

This study focuses on identifying source and frequency of noise pollution in Yazd, Iran. For data collection, we used two approaches: First we selected 55 monitoring stations for 122 km grid network; the distance between two stations was 2 km. Then, at the same time, we measured the sound pressure level (SPL) at main roads; the distance between two monitoring stations in this case was 1 km. Aft...

This study presents an approach to GMM-based speech conversion using maximum a posteriori probability (MAP) adaptation. First, a conversion function is trained using a parallel corpus containing the same utterances spoken by both the source and the reference speakers. Then a non-parallel corpus from a new target speaker is used for the adaptation of the conversion function which models the voic...

In this paper, we propose an approach to obtain super-resolved image and super-resolved depth map using photometric cue. The images are captured using different light source positions which are assumed to be known. The surface of the object is assumed to be Lambertian. We model the high resolution structure (surface gradients) as a Markov Random Field (MRF) and use graph cuts with discontinuity...

MOTIVATION A high-quality assembly of reads generated from shotgun sequencing is a substantial step in metagenome projects. Although traditional assemblers have been employed in initial analysis of metagenomes, they cannot surmount the challenges created by the features of metagenomic data. RESULT We present a de novo assembly approach and its implementation named MAP (metagenomic assembly pr...

The paper presents a framework for autonomous search for a diffusive emitting source of a tracer (e.g., aerosol, gas) in an environment with an unknown map of randomly placed and shaped obstacles. The measurements of the tracer concentration are sporadic, noisy and without directional information. The search domain is discretised and modelled by a finite two-dimensional lattice. The links in th...

This paper presents new methods for the detection of an unknown map projection and its parameters from a map. Corresponding 0D2D elements both on the analyzed map and a sphere (or a reference map) represent the source matter for the analysis. The following cartographic parameters (i.e., constants of a projection P) are estimated: R, k, k, 0, 0, Δx, Δy. Our solution minimizes L2 norm of resi...

Digital communications systems commonly use compression (source coding) and error control (channel coding) to allow efficient and robust transmission of data over noisy channels. When compression is imperfect, some residual redundancy remains in the transmitted data and can be exploited at the decoder to improve the decoder’s probability-of-error performance. A new approach to joint source-chan...
