For inpatient, the environment in room is extremely important for the rehabilitation of patient, comfort level gradually at
For the factor of consideration.Particularly, for window or windowsill, windowing ventilation faces outdoor dust, the suspension in air can
Object, automobile noise etc. have no to enter in ward with blocking, and seriously affect the health of patient, influence the rest and work of patient
Make.If encountering the weather of blowing and raining, sandstorm or outdoor serious pollution, can't open a window ventilation.Meanwhile in closing ward
In the case of, oxygen is limited in ward, due to the respiration of patient, is consumed oxygen and is completely converted into carbon dioxide, make
Oxygen owning amount declines in ward, and carbon dioxide composition rises, and causes patient respiration to have some setbacks, influences sleep quality.Ordinary people
Everyone can breathe out 20 liters of carbon dioxide per hour, account for the 4% of exhaled gas total amount, and the carbon dioxide content in fresh air is

In addition, image filtering, i.e., press down the noise of target image under conditions of retaining image minutia as far as possible
System, is indispensable operation in image preprocessing, and the quality for the treatment of effect will directly influence subsequent image processing and divide
The validity and reliability of analysis.
Not perfect due to imaging system, transmission medium and recording equipment etc., digital picture formed at it, transmission log mistake
The often pollution by a variety of noises in journey.In addition, certain links in image procossing when the picture object inputted and are not so good as pre-
Also noise can be introduced when thinking in result images.These noises often show as one on the image and cause the isolated of stronger visual effect
Pixel or block of pixels.Generally, noise signal it is uncorrelated to the object to be studied it occur with useless message form, upset figure
The observable information of picture.For data image signal, psophometer is either large or small extreme value, these extreme values are acted on by plus-minus
On the true gray value of image pixel, cause bright, dim spot to interfere image, greatly reduce picture quality, influence image restoration,
The progress of the subsequent work such as segmentation, feature extraction, image recognition.The filter for constructing a kind of effectively inhibition noise must be taken into consideration
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.
One of common image filtering mode is nonlinear filter, it is, in general, that when signal spectrum and noise frequency
When composing aliasing or such as the noise as 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.
