Description of the drawings
Embodiment of the present invention is described below with reference to attached drawing, wherein：
Fig. 1 is the structure box according to the security window control platform based on image procossing shown in embodiment of the present invention
Figure.
Reference numeral：1 first humidity sensor；2 second humidity sensors；3 proximity sensors；4 sheet metals；5 motors drive
Dynamic device；6 direct current generators
Specific implementation mode
The embodiment of the security window control platform based on image procossing of the present invention is carried out below with reference to accompanying drawings
It is described in detail.
The material of window generally speaking can be divided into three categories：Wooden, plastic-steel, aluminium alloy.Three has his own strong points.
Plastic-steel：Because being plastic material, weight is small, and heat-proof quality is good, and price is relatively low.Because often wanting
In face of exposing to wind and rain, the sun shines, so people is most allowed to concern the anti-aging problem of plastic-steel window.In fact, the plastic-steel window of high-quality
Service life up to 100 years or so.
Aluminium alloy：Because being metal material, there is no problem of aging, and firm, impact resistance, intensity are big.But
It is exactly heat-proof quality that aluminum window, which is easiest to attacked weakness, because metal be heat good conductor, it is extraneous with it is indoor
Humidity can be transmitted with the frame of window.
But it is worth query, the ratio on a fan window shared by frame is simultaneously not very big, and window is not one block of metal
Plate, but the glass of frame is inlayed, the heat transmitted by frame edge strip actually can be to there is the generation of the indoor humidity of warmer, air-conditioning
Great influence？
But that precautions averts perils is good, this problem, uses " bridge cut-off " skill on the aluminium alloy window having in order to prevent
Art adds one layer of resin material that is, in aluminum alloy window frame, has thoroughly broken off the approach of heat conduction.
It is wooden：Comparatively, wooden should be forms frame material the most perfect, no matter from heat-insulated, sound insulation angularly
For have apparent advantage, and inherent texture and natural figure are more moving.It is practical although wooden
On some be used to do the solid wood of window frame and have already been through processing special layer by layer, not only without moisture, it is desirable that it is higher even
Fat is sucked, so, so-called wooden actually as fossil, solid wood after treatment is only protected
The appearance of timber has been stayed, quality is but completely different, will not cracking deformation, less suffers insect bite with worry, is corroded, moreover,
Intensity also greatly increases.
In addition, also a kind of frame structure is referred to as aluminium Bao Mu, the outdoor part of wood frame is one layer of aluminium alloy structure,
In fact, this be combine wood frame thermal insulation is good and advantage that intensity of aluminum alloy is high, integrate, maximize favourable factors and minimize unfavourable ones.
The wooden unique disadvantage of window is exactly that cost is too high.
Current window control model falls behind, and automatic window can not be carried out according to external circumstances or closes window control, in order to gram
Above-mentioned deficiency is taken, the present invention has built a kind of security window control platform based on image procossing, asked for solving above-mentioned technology

Two basic problems：The noise that can be effectively removed in target and background；Meanwhile can protect well image object shape,
Size and specific geometry and topological features.
In common image filtering pattern one is nonlinear filters, it is, in general, that when signal spectrum and noise frequency
When composing aliasing or such as the noise caused by mission nonlinear or there are non-gaussian to make an uproar when containing nonadditivity noise in signal
Sound etc.), traditional linear filter technology, if Fourier converts, while filtering out noise, always blurred picture is thin in some way
Section (such as edge) and then the extraction property reduction for leading to the positioning accuracy and feature as linear character.And nonlinear filter is
Based on a kind of Nonlinear Mapping relationship to input signal, often a certain specific noise approximatively can be mapped as zero and retained
Signal wants feature, thus it can overcome the shortcoming of linear filter to a certain extent.
