despite recent advances in video inpainting techniques, reconstructing large missing regions of a moving subject while its scale changes remains an elusive goal. in this paper, we have introduced a scale-change invariant method for large missing regions to tackle this problem. using this framework, first the moving foreground is separated from the background and its scale is equalized. then, a ...

We have analyzed a set of deep ROSAT observations with a total sky coverage of 40 square degrees to search for clustering of faint X-ray sources. Using the resulting catalog of discrete X-ray sources, we detect, for the first time in X-rays, a positive correlation on angular scales of 0.5–10. When corrected for a bias due to limited spatial resolution which amplifies the correlation, the observ...

A theoretical formulation for the two-point correlation function on a light-cone is developed in the redshift space. On the basis of the previous work by Yamamoto & Suto (1999), in which a theoretical formula for the two-point correlation function on a light-cone has been developed in the real space, we extend it to the formula in the redshift space by taking the peculiar velocity of the source...

Binary sequences with good correlation properties play an important role in many secure communication systems and testing of systems. In this paper, we describe and illustrate sets of pseudorandom sequences from de Bruijn graphs which have good correlation functions and critically analyze how we investigate all homomorphisms that give low correlation values between the binary sequences. We comp...

A controlled subjective test was carried out to assess selected spatial qualities of three virtual home theatre processors. The subjective results were used to evaluate a number of objective measurements based on the interaural cross-correlation coefficient (IACC). A novel implementation of the IACC was found which appears to correlate well with the subjective data.

According to the advantages of chaotic analog sequences and chaotic binary sequences, this paper proposes a method generating chaotic binary spread-spectrum sequence by multilevel quantifying. This paper proved that even correlation and odd correlation between such sequences of length N are all Gaussian distributed with mean 0 and variance N, the even of mean-square cross-correlation is N, and ...

human resource productivity is an important subject in theory and practice, so increase of productivity is the first priority in most of organizations. the main purpose of most organizations is creating value for their shareholders. so it is necessary to understand effect of human resource productivity in achieving this goal and find the obstacles. the purpose of this research is examining the ...
