A image slice calculates the standard deviation of form and aspect signal component value in the wherein space HSB of each pixel.
In the extended pattern electronic violin, further includes:
It is sliced output equipment, is connect with standard deviation identification equipment, for calculating each standard of each image slice
The mean value of difference, and the image slice using standard deviation more than the mean value exports the subsequent processing image as slice to be analyzed
One or more of slice to be analyzed；
Homomorphic filtering equipment judges that equipment and the slice output equipment are connect with the posture respectively, for described
One or more slices to be analyzed carry out homomorphic filtering processing respectively, to obtain corresponding one or more homomorphic filtering slices,
And one or more of homomorphic filterings slice is replaced the subsequent processing image and exported and judges equipment to the posture.
In the extended pattern electronic violin: the standard deviation identification equipment includes space conversion unit, for calculating
Form and aspect signal component value, luminance components value and saturation degree signal component value in the space HSB of each pixel in each image slice out.
In the extended pattern electronic violin, further includes:
Parallel communication interface, setting identify between equipment and the slice output equipment in the standard deviation, are used for as institute
The image data communication stated between standard deviation identification equipment and the slice output equipment provides channel；
Wherein, the parallel communication interface is arranged to 8 data communication interfaces or 16 data communication interfaces.
In addition, the image filtering mode that the homomorphic filtering equipment uses, in the condition for retaining image minutia as far as possible
Under the noise of target image is inhibited, be indispensable operation in image preprocessing, the quality for the treatment of effect will be straight
Connect the validity and reliability for influencing subsequent image processing and 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.
Using extended pattern electronic violin of the invention, can not implement for electronic violin in the prior art to bridge appearance
The technical issues of real-time monitoring of gesture, carries out real-time monitoring and analysis by the posture to bridge, with timely when posture is wrong
User is reminded to be modified；Meanwhile more than Lai Natu and the gray level resolution promotion limited the quantity, treated by gray level resolution
The gray level resolution that image carries out specific position image block compares, and is adaptively determined with the multiple proportion based on gray level resolution
The number that subsequent multiple gray level resolution is promoted is executed to increase resolution image, to guarantee image grayscale resolution adjustment effect
Fruit；To solve above-mentioned technical problem.
