FUSION FRAMES AND g-FRAMES IN HILBERT C*-MODULES
International Journal of Wavelets, Multiresolution and Information Processing, 2008The notion of frame has some generalizations such as frames of subspaces, fusion frames and g-frames. In this paper, we introduce fusion frames and g-frames in Hilbert C*-modules and we show that they share many useful properties with their corresponding notions in Hilbert space.

Some Results on Fusion Frames and g-Frames
Results in Mathematics, 2018The author studies some properties of fusion frames and \(g\)-frames in relation to frames. She introduces the notion of upper and lower redundancies of \(g\)-frames and shows that some of the desirable results known about the redundancies on frames and fusion frames carry over \(g\)-frames.

Frame Fusion for Video Copy Detection
IEEE Transactions on Circuits and Systems for Video Technology, 2011Content-based video copy detection is very important for copyright protection in view of the growing popularity of video sharing websites, which deals with not only whether a copy occurs in a query video stream but also where the copy is located and where the copy is originated from.

Frames for fusions of modal logics
Journal of Applied Non-Classical Logics, 2018Let us consider multimodal logics and . We assume that is characterised by a class of connected frames, and there exists an -frame with a so-called -starting point.

Frames are families of vectors in a (separable) Hilbert space H, which generalize the notion of an orthonormal basis and provide the possibility to represent and re- construct vectors in H in a non-unique, redundant and stable way. These properties of frames are desired for a vast number of applications, e.g.

On the stability of fusion frames (frames of subspaces)
Acta Mathematica Scientia, 2011Abstract A frame is an orthonormal basis-like collection of vectors in a Hilbert space, but need not be a basis or orthonormal. A fusion frame (frame of subspaces) is a frame-like collection of subspaces in a Hilbert space, thereby constructing a frame for the whole space by joining sequences of frames for subspaces.

Fusion algorithm not affected by the picture frame
Systems and Computers in Japan, 1985AbstractThis paper discusses the properties and the algorithms of the fusion operations, which are one of the fundamental techniques of binary image processing. First, a theoretical discussion is made for infinitely spread images, deriving several properties for the fusion operations.
