In overlap-add synthesis of sinusoidal partials, amplitude modulation distortion can occur in the overlap region if the partial frequencies in successive frames diier. The frame-to-frame frequency changes can be accommodated by synthesizing linearly time-varying sinusoids (chirps) in adjacent frames. In this paper we present a new approach to chirp synthesis in which the distortion is eliminate...

We present four human behavioral experiments to address the question of intuitive granularities in fundamental spatial relations as they can be found in formal spatial calculi. These calculi focus on invariant characteristics under certain (especially topological) transformations. Of particular interest to this article is the concept of two spatially extended entities overlapping each other. Th...

We present an approach for finding the overlap area between two ellipses that does not rely on proxy curves. The Gauss-Green formula is used to determine a segment area between two points on an ellipse. Overlap between two ellipses is calculated by combining the areas of appropriate segments and polygons in each ellipse. For four of the ten possible orientations of two ellipses, the method requ...

Discriminant analysis DA is used for the measurement of estimates of a discriminant function by minimizing their group misclassifications to predict group membership of newly sampled data. A major source of misclassification in DA is due to the overlapping of groups. The uncertainty in the input variables and model parameters needs to be properly characterized in decision making. This study com...

We present our ongoing work in addressing the issue of overlapped speech in speaker diarization through the use of overlap segmentation, overlapped speech exclusion, and overlap segment labeling. Using feature analysis, we identify the most salient features from a candidate list including those from our previous system and a set of newly proposed features. In addition, through independent optim...

The possibility of di!erences in phonetic alignment of phonological segments was examined by contrasting consonant sequences at word boundaries in Russian and English. In Experiment 1, two acoustic measures of consonant overlap, percent released and duration ratio, are computed for stop sequences at word boundaries, and results for English and Russian are compared. While signi"cant variation du...

Our paper deals with the information system design when several responsibilities share a common subset of information. First, we show how to define information overlap situations between these responsibilities. Then we focus on these situations in order to understand how the responsibility areas can avoid information coordination misunderstandings.The study of these situations shows how to defi...

This paper addresses the problem of aerial image matching. We analyze existing approaches to this problem and show that, though the modern algorithms cope with the task quite well, their results are deteriorated in case of low overlap and significant rotation angle between the images. A two-stage feature-based image matching scheme is presented. It is shown that preliminary stage of simplified ...

Traditional map-labeling algorithms ensure that the labels being placed do not overlap each other, either by omitting labels or scaling them. This is undesirable in applications where the points to be labeled are moving. We develop and experimentally evaluate a heuristic for labeling moving points. Our algorithm labels all the points with labels of a fixed size, while trying to minimize the num...
