The study of the c$k$-fusions frames shows that the emphasis on the measure spaces introduces a new idea, although some similar properties with the discrete case are raised. Moreover, due to the nature of measure spaces, we have to use new techniques for new results. Especially, the topic of the dual of frames  which is important for frame applications, have been specified  completely for the c...

In this article, we consider pair frames in Banach spaces and   introduce Banach pair frames. Some various concepts in the frame theory such as frames, Schauder frames, Banach frames and atomic decompositions are considered as   special kinds of (Banach) pair frames.  Some frame-like inequalities  for (Banach)  pair frames are presented. The elements that participant  in the construction of (Ba...

introduction: hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mtc- rbc scan is highly specific and is the method of choice for this differentiation. this scintigraphy is performed in planar and spect modes. these two procedures are in agreement most of the times, however since spect is ...

this paper is dedicated to propose an algorithm in order to generate the certain isomers of some well-known fullerene bases. furthermore, we enlist the bipartite edge frustration correlated with some of symmetrically distinct in nite families of fullerenes generated by the o ered process.

In this paper airborne thermal videos are used to detect vehicles. The movement of the camera is estimated from the optical flow using projective planar homographies as transformation model. A three level classification process is proposed: On the first level the eigenvalues of the squared averaged gradient are used to extract interest locations that can be put into correspondence with other su...

In this paper we present a method to efficiently detect moving objects namely vehicles in airborne thermal videos. The motion of the sensor is estimated from the optical flow using projective planar homographies as transformation model. A three level classification process is proposed: On the first level we extract interest location applying the Foerstner operator. These are subject to the seco...

We have developed an algorithm for automated detection of the dynamic pattern characterizing flashes of fluorescence in video images of membrane fusion. The algorithm detects the spatially localized, transient increases and decreases in brightness that result from the dequenching of fluorescent dye in phospholipid vesicles or lipid-enveloped virions fusing with a planar membrane. The flash is i...

Classical dissections convert any planar polygonal region onto any other polygonal region having the same area. If two convex polygonal regions are isoparametric, that is, have equal areas and equal perimeters, our main result states that there is always a dissection, called a complete dissection, that converts not only the regions but also their boundaries onto one another. The proof is constr...

We propose a method to recover dense 3D scene flow from stereo video. The method estimates the depth and 3D motion field of a dynamic scene from multiple consecutive frames in a sliding temporal window, such that the estimate is consistent across both viewpoints of all frames within the window. The observed scene is modeled as a collection of planar patches that are consistent across views, eac...
