Many complicated software packages make the operation difficult for end users. To acquire the skills for software operation, supporting end users to learn operating methods by themselves is effective. When in learning operating methods, it is important for end users to check the overview of the operating methods and their current step in the sequence of operations. On the basis of the overview ...

The level set of an elliptic function is a doubly periodic point set in C. To obtain a wider spectrum of point sets, we consider, more generally, a Riemann surface S immersed in C2 and its sections (“cuts”) by C. We give S a crystallographic isometry in C2 by defining a fundamental surface element as a conformal map of triangular domains and S as its extension by reflections in the triangle edg...

A tiling of a subset A of R is a countable set T of tiles in R such that: (1) ∪T = A, (2) whenever S, T belong to T and are distinct we have intS ∩ intT = ∅. Part of a pentagonal tiling is shown in Figure 2. A patch is a tiling by finitely many tiles of a connected, simply connected subset of R which cannot be disconnected by removing one point. To say that a patch A belongs to a tiling T means...

We present a method to estimate a dense and sharp depth map using multiple cameras. A key issue in obtaining sharp depth map is how to overcome the harmful in uence of occlusion. Thus, we rst propose an occlusion-overcoming strategy which selectively use the depth information from multiple cameras. With a simple sort and discard technique, we resolve the occlusion problem considerably at a slig...

Map digitization is one of the most important means of geographic data acquisition. Automatic extraction of geographic features from scanned maps is the key technique to improve the efficiency of map digitization. With regard to linear feature extraction from color topographic map images, it is usually performed by interactive or automatic line tracking based on color separated binary images. B...

A challenge in characterizing active region (AR) coronal heating is separating transient (bursty) loop from the diffuse background (steady) heating. We present a method of quantifying heating's bursty and steady components ARs, applying it to FeXVIII (hot94) emission an AR observed by SDO/AIA. The maximum, minimum, average brightness values for each pixel, over 24 hour period, yield maximum-bri...

In this article, we propose a simple and efficient method for computing an image saliency map, which performs well on both salient region detection and as well as eye gaze prediction tasks. A large number of distinct sub-windows with random co-ordinates and scales are generated over an image. The saliency descriptor of a pixel within a random sub-window is given by the absolute difference of it...

For sparse exponent sequences (k) 1 ?1 , satisfying a suitablèseparation condition' deened by an auxiliary sequence , one has a `coeecient map' C giving (c k) 1 ?1 =: c from observation of f = P 1 k=?1 c k e ii k t on any arbitrarily small interval ?; ]. In terms of , we estimate the norm of C : L 2 ?; ] ! ` 2 , asymptotically as ! 0. In particular, for (k) 1 ?1 k p (p > 1) we get a bound which...

In this paper we describe a new method for detecting and tracking multiple persons with a stereo camera. The method is based on the idea of the plan-view map, i.e., the 2D histogram of projected 3D measurements from the camera. It estimates the statistical feature in an optimal window, e.g., a rectangular region, on the histogram, considering stereo measurement error, human breadth, and height....
