In this paper, according to the demands of the user Video Blaster SE100, the authors present how to make continuous image chasing and real time compression quickly and simply by using Windows MCI so as to improve the efficiency of such software as the users develop.

A novel algorithm for reconstructing high resolution image is proposed based on 2D interpolation kernel by use of continuous image sampling and interpolation formula.

The sources of noises and artificial frequency in the process of imaging are sampling continuous image and quantification of energy by using spatial light modulator of light address, and the produced noises is mainly Gauss noises, it was analyzed in theory.

A hardware solution for real time line extraction from broadband image signals is presented. The realization is based upon FPGA+DSP architecture. The line extraction module can process both the common frame based video signals and the continuous image signals generalized by a line array CCD.

It is shown that a T_2 space is S—closed if it is a θ—S continuous image of a compact space, and, in addition, that a space is nearly compact if it is an almost-continuous image of a compact space.

The principal result of the paper is that a topological space X has a σ—point finite base if and only if it is the open,compact,continuous image of a metric space.

Because of high resolution rate, great amounts of pixels, enormous memory capacity is necessary, and smoothing continuous image makes high speed a must.

In order to mimic analog halftoning techniques, clustered-dot ordered dithering or Amplitude Modulated (AM) halftoning produces this illusion by varying the size of printed dots according to the gray level of an original continuous image.

It is proved that the basic space is Hilbert space. Simulteniously,some results concerning the convergence and the continuous image are also analysed. The above lays the foundation for demonstration of properly-posedness and convergence of the approximate problem.

Furthermore, we establish a generalization of the well-known fact that the continuous image of a compact set is compact.

Based on a continuous image model comprising blur and noise introduced by an imaging system we analyze three different intensity models of 3D tubular structures with increasing complexity.

This paper suggests a high-level continuous image model for planar star-shaped objects.

We consider a continuous image model thatrepresents the blur as well as noise introduced by an imagingsystem.

One is two-dimensional, while the second is countable, and leads to an example of a countable, compact, T1 space with a countable base which is not the continuous image of any compact Hausdorff space.

In this paper S—closed spaces are characterized in terms of semi regular cover.Two conditions, for whih products ×X_a and X×Y are S—closed, are given.It is shown that a T_2 space is S—closed if it is a θ—S continuous image of a compact space, and, in addition, that a space is nearly compact if it is an almost-continuous image of a compact space. Connection among quasi-H closedness, weakly continuous mapping and compactness is also shown。

An open cover of a space is called a b2 -cover, if it has a refinement suchthat each is a locally finite family in the subspace where denotes the first infinite ordinal number. A space X is said to have property b2, if each open cover of X is a bf -cover. The property B(LF, w2) [10] implies property b2 but not conversely. We do not require paracompact spaces to satisfy any separation axioms in our terminology. The main results are as follows.Theorem 1. For any space X the following are equivalent.(i) X is expandable.(ii)...

An open cover of a space is called a b2 -cover, if it has a refinement suchthat each is a locally finite family in the subspace where denotes the first infinite ordinal number.

We do not require paracompact spaces to satisfy any separation axioms in our terminology. The main results are as follows.Theorem 1. For any space X the following are equivalent.(i) X is expandable.(ii) Every directed b2 -cover of X has a closure preservirg closed refinement such that {F :F} covers X.(iii) Every directed bf -cover of X has a o-closure presesving closed refinement such that {F :F} covers X.(iv) Every interior-preserving directed A-cover of X has a o-cushioed open refinement.Theorem2. A space is paracompact, if and only if it is o-expandable and has property b2.Corollary3. For any space X the following are eguivalent.(i) X is paracompact.(ii) (Junnila [3]) X is 0-expandable and submetacompact.(iii) (Jiang [1]) X is 0-expandable and strictly quasi-paracompact.(iv) (Jiang [2]) X is 0-expandable and has property b1 .(v) X is 0-expandable and weakly 0 -refinable.(vi) X is 0-expandable and has property B(LF, w2).Theorem4. A continuous image of an expandable space under a closed and bi-guotient mapping is expandable.Corollary5. A continuous image of a paracompact space under a closed and bi-guotienl mapping is paracompact.(1980 AMS Subject Classification. 54D18).

The principal result of the paper is that a topological space X has a σ—point finite base if and only if it is the open,compact,continuous image of a metric space.
