Description

Intelligent live image filtering system
Technical field
The present invention relates to image filtering field more particularly to a kind of intelligent live image filtering systems.
Background technique
Image filtering inhibits the noise of target image under conditions of retaining image minutia as far as possible, is Indispensable operation in image preprocessing, treatment effect quality will directly influence subsequent image processing and analysis have Effect property and reliability.
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.
Summary of the invention
The present invention provides a kind of intelligent live image filtering systems, can be obtained by high-precision image procossing The history of the user of washbowl uses data, and the history of the user based on washbowl uses data to the height of washbowl The height of adjustable closed part is voluntarily adjusted.
According to an aspect of the present invention, a kind of intelligent live image filtering system is provided, the system comprises:
The collector nozzle of washbowl is arranged in adjustable height closure member, and the height adjustment based on closure member is lauched slit width Degree, wherein the height of closure member is adjusted higher, and the gap width that is lauched of the washbowl of the height adjustment based on closure member is got over Greatly;
Scene capture equipment is arranged in toilet, for shooting in front of washbowl, to obtain frontal scene Image, and export the frontal scene image;
Recursion process equipment is connect with the scene capture equipment, for receiving the frontal scene image, before described Square scene image executes adaptive recursive filtering processing, to obtain the first filtering image;
Signal-to-noise ratio detection device is connect with the Recursion process equipment, for receiving first filtering image, and to institute The signal-to-noise ratio for stating the first filtering image is parsed, and when the signal-to-noise ratio being resolved to is more than or equal to preset ratio threshold value, issues nothing Signal need to be handled, when the signal-to-noise ratio being resolved to is less than preset ratio threshold value, issues and continues filtering signal;
Wavelet filtering equipment is connect with the signal-to-noise ratio detection device, for when receiving the continuation filtering signal, Wavelet filtering processing is executed to obtain and export the second filtering image to first filtering image, be also used to receive it is described When without handling signal, exported using first filtering image as the second filtering image;
Data storage device, for the signal-to-noise ratio piecemeal table of comparisons to be stored in advance, the signal-to-noise ratio piecemeal table of comparisons is saved It take signal-to-noise ratio grade as the corresponding image block of index, wherein in the signal-to-noise ratio piecemeal table of comparisons, signal-to-noise ratio grade Higher, corresponding image block is smaller.
It can be seen that the present invention at least has following several key inventives point:
(1) history of the user based on washbowl uses data, to the height of the adjustable height closure member of washbowl It is adjusted, so that the preference height for being lauched gap width and being adjusted to user of washbowl, so that having catered to every makes The use habit of user;
(2) two stage filter linkage treatment mechanism is used, is filtered using the higher wavelet filtering equipment of complexity as rear class Wave device is only unsatisfactory for noise in prime filtering using the lower recursive filtering equipment of complexity as prime filter apparatus In the case where requiring, just the complicated wavelet filtering equipment of starting carries out secondary filtering, thus not influencing the same of filter effect When, reduce the operand of filtering;
(3) the image block mechanism based on the real-time signal-to-noise ratio grade of image is established, while passing through the specific of three primary colours channel The region to be identified where target is judged in numerical analysis, to improve the precision of image recognition.
Detailed description of the invention
Embodiment of the present invention is described below with reference to attached drawing, in which:
Fig. 1 is the structural schematic diagram according to the intelligent live image filtering system shown in embodiment of the present invention.
Specific embodiment
The embodiment of intelligent live image filtering method of the invention is described in detail below with reference to accompanying drawings.
The a little higher than table top of basin side palpus of washbowl, but had to smoothly with table top joint, it is therefore intended that table top will be splashed On water wipe back it is unobstructed when being gone in basin, while be convenient for table top cleaning.Table top itself has to select surface smooth Material, edge and two corners must be round and smooth, in order to avoid collide with.The finish of washbowl itself is also extremely important, highly polished pelvic surface of sacrum So that the sundries in water is not easy attaching surface, comparatively reduces the number to need cleaning.Conventionally, the depth and peace of washbowl The intensity of the tap water flow of top loading is directly proportional, i.e., deep basin could install the strong faucet of water flow.Ten million can not be the bottom of at Coarse tap is installed on the shallower basin in portion, with this can make one to splash when with water.Enough arcs will be arranged at the bottom of basin Degree, cannot be too flat, and otherwise water can accumulate inside.
Currently, the lower water speed of washbowl is adjusted by the height of the adjustable height closure member built in it, Adjustable height closure member is higher, then the lower water speed of washbowl is faster, adjustable height closure member be by manually voluntarily controlling, It can not be carried out automatically controlling according to the usage history data of user.
