Vector Space Formulation of Two-Dimensional Signal Processing Operations
نویسنده
چکیده
Signal processing operations on two-dimensional fields of data can be cast into a vector space formulation. This formulation often leads to a simplified analysis of two-dimensional processing systems and to the discovery of more efficient computational algorithms. This paper considers the general representation of two-dimensional fields as vectors and discusses common types of operators on these data vectors. Particular emphasi~ is given to various forms of the superposition operation. Computation of superposition operations using unitary transform techniques is analyzed.

FUZZY HV -SUBSTRUCTURES IN A TWO DIMENSIONAL EUCLIDEAN VECTOR SPACE
In this paper, we study fuzzy substructures in connection withHv-structures. The original idea comes from geometry, especially from thetwo dimensional Euclidean vector space. Using parameters, we obtain a largenumber of hyperstructures of the group-like or ring-like types. We connect,also, the mentioned hyperstructures with the theta-operations to obtain morestrict hyperstructures, as Hv-groups...
متن کاملThree Dimensional Localization of an Unknown Target Using Two Heterogeneous Sensors
Heterogeneous wireless sensor networks consist of some different types of sensor nodes deployed in a particular area. Different sensor types can measure different quantity of a source and using the combination of different measurement techniques, the minimum number of necessary sensors is reduced in localization problems. In this paper, we focus on the single source localization in a heterogene...

Identifying spoken language automatically is to identify a language from the speech signal. Language identification systems can be divided into two categories, spectral-based methods and phonetic-based methods. In the former, short-time characteristics of speech spectrum are extracted as a multi-dimensional vector. The statistical model of these features is then obtained for each language. The ...

متن کاملIntroduction to a simple yet effective Two-Dimensional Fuzzy Smoothing Filter
Annihilation or reduction of each kind of noise blended in correct data signals is a field that has attracted many researchers. It is a fact that fuzzy theory presents full capability in this field. Fuzzy filters are often strong in smoothing corrupted signals, whereas they have simple structures. In this paper, a new powerful yet simple fuzzy procedure is introduced for sharpness reduction in ...
