An algorithm and a program for detecting the boundaries of water bodies autopilot module asurface robot are proposed. A method objects on satellite maps by finding color in HSV space, using erosion, dilation - methods digital image filtering is applied.The following operators constructing contours investigated: Sobel,Roberts, Prewitt, from them one that detects boundary more accurately selected...

An iris recognition algorithm is implemented using morphological image processing, Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA). The suggested occlusion removal technique is implemented using erosion and dilation operators, and compared against a training set without occlusion removal and one that only keeps one half of the iris. The resulting comparison shows that ...

The article is devoted to building various dilatations of linear operators. explicit construction a unitary dilation compression operator considered. Then the J-unitary dilatation bounded constructed by means knot concept operator. Using Pavlov method, we construct self-adjoint dissipative We consider spectral and translational representations densely defined with nonempty set regular points. a...

the aim of this study was to evaluate the effect of estradiol (e2), oxytocin (ot), relaxin (relaximol) injection and prostaglandin e1 (misoprostol) suppository on the cervix dilation, time of cervical dilation persistency and pregnancy rate of zandi ewes using artificial insemination. eighty 3-4 years old and 55±2.5 kg weight ewes were used for this study. in experiment 1, the ewes were assigne...

An improvement of the majority gate algorithm suitable for grey scale morphological operations is presented in this letter. The redundancy of temporal signals led to a simplified hardware implementation. It is shown that max/min operators can be computed by the same circuit. A new pipelined systolic array architecture based on this circuit is illustrated for dilation/erosion operations. 2 Intro...

Mathematical Morphology (MM) is a tool that can be applied to many digital image processing tasks include the reduction of impulsive or salt and pepper noise in grayscale images. The morphological filters used for this task are resulting from two basic operators: erosion dilation. However, when level contamination higher, these tend distort image. In work we propose pair operators with properti...

We consider contractive homomorphisms of a planar algebra A(Ω) over a finitely connected bounded domain Ω ⊆ C and ask if they are necessarily completely contractive. We show that a homomorphism ρ : A(Ω) → B(H) for which dim(A(Ω)/ ker ρ) = 2 is the direct integral of homomorphisms ρT induced by operators on two dimensional Hilbert spaces via a suitable functional calculus ρT : f 7→ f(T ), f ∈ A(...

For classical dynamical systems time operators are introduced as selfadjoint operators satisfying the so called weak Weyl relation (WWR) with the unitary groups of time evolution. Dynamical systems with time operators are intrinsically irreversible because they admit Lyapounov operators as functions of the time operator. For quantum systems selfadjoint time operators are defined in the same way...

This paper generalizes the notion of symmetrical neighbourhoods, which have been used to define connectivity in the case of sets, to the wider framework of complete lattices having a sup-generating family. Two versions (weak and strong) of the notion of a symmetrical dilation are introduced, and they are applied to the generation of “connected components” from the so-called “geodesic dilations”...
