The specific embodiment
Key problem in technology of the present utility model is B ultrasonic fetus image is carried out Intelligent Recognition, whether the image that is automatically identified when pre-treatment by machine contains sex of foetus position and the sex of foetus position particular location in image, uses mosaic or other shielding patterns that the sex position is blocked then.
Fig. 1 is the sketch map of the B ultrasonic equipment of this utility model one better embodiment.This B ultrasonic equipment 10 comprises a ultrasonography sniffer 11, a ultrasonography generating apparatus 12, a sex screen unit, and the sex screen unit is a smart card 13 in this example, and an image display device 14.Ultrasonography sniffer 11 adopts ultrasound wave that the fetus image in the pregnant woman uterus is surveyed; The signal that ultrasonography generating apparatus 12 is used for detecting according to ultrasonography sniffer 11 generates the fetus image.Sex shielding smart card 13 is at first found out the sex of foetus position from the fetus image that ultrasonography generating apparatus 12 generates, and then it is shielded, and the image at shielding sex position shows by image display device 14.
Sex shielding smart card 13 comprises memorizer 15, an image pretreatment module 16, an image segmentation module 17, a sex of foetus identification module 18 and a sex of foetus shroud module 19 of depositing sex of foetus view data parameter.Image pretreatment module 16 is used for the fetus image that ultrasonoscopy sniffer 11 generates is carried out pretreatment such as filtering and noise reduction; Image segmentation module 17 is carried out pretreatment according to the parameter in the memorizer 15 to pretreated fetus image, fetus view data parameter storage 15 has reflected the sex of foetus position characteristics of image of different anemia of pregnant woman's positions and different gestational age, the Primary Location point that extracts segmentation threshold and 18 pairs of doubtful sexes of sex of foetus part Identification module position when being used for image segmentation module 17 and carrying out image segmentation is discerned, and is partitioned into the image at least one doubtful sex position; The fetus image that sex of foetus identification module 18 is used for after cut apart identifies the sex of foetus position; Sex of foetus shroud module 19 is used for generating mosaic or other shielding patterns at the sex of foetus position, with shielding sex of foetus position.
The particular flow sheet that Fig. 2 shields the sex of foetus position for this utility model.The key step of this method is as follows:
S10: the original ultrasonoscopy to input carries out the image pretreatment, and this step has this image pretreatment module 16 to finish.
Signal to noise ratio is low, the speckle noise phenomenon serious because the restriction of ultrasonic device image-forming principle, ultrasonoscopy exist and characteristics such as imaging object edge blurry, therefore need carry out pretreatment to original B ultrasonic image.Can adopt auto-adaptive filtering technique that original B ultrasonic image is carried out pretreatment, this technology is at first analyzed the whole signal noise ratio level and the speckle noise order of severity of ultrasonoscopy, then each the picture element portion in the image is judged that by the intensity profile situation of local neighborhood around it this pixel is positioned at homogeneous region or different filtering modes is selected in the non-homogeneous zone.Under the occasion that algorithm speed is had relatively high expectations, can directly use traditional filtering modes such as mean filter that image is carried out pretreatment.
S20: pretreated ultrasonoscopy is carried out image segmentation, and this step is finished by the image segmentation module.
Because ultrasonic fetus image imaging content is very complicated, and the sex position imaging difference of different all numbers, different anemia of pregnant woman's position and different fetus individualities is very big, if conventional art means such as pretreated ultrasonoscopy use template similarity coupling are unpractical and do not have feasibility.For the progressive information of extracting in the image, need carry out image segmentation to pretreated image and handle.
When the method that adopts adaptively selected segmentation threshold is cut apart, need set up fetus image pattern storehouse.Fetus image pattern storehouse is made up of 20000 width of cloth typical case fetus image, wherein includes the sex of foetus position in 9273 width of cloth images, and 10727 width of cloth images do not comprise the sex of foetus position.The fetus image of these images from 16 weeks of gestational age to 34 weeks do not limit anemia of pregnant woman's position from the ultrasound diagnosis collection in worksite during collection, comprise multiple anemia of pregnant woman's positions such as dorsal position, right arm reclining and left lateral position.The particular location that whether comprises sex of foetus position and sex position in the image is confirmed jointly by several veteran gynecologists.This image pattern storehouse has fully covered the sex of foetus station diagram picture of different anemia of pregnant woman's positions and different gestational age, is a standard sample database describing sex of foetus station diagram picture, and this sample the stock be placed in the memorizer 15.
S30: extract the Primary Location point at doubtful sex of foetus position, this step is finished by sex of foetus part Identification module 18.
The sex of foetus position only accounts for very little a part of area usually in fetus B ultrasonic image, for example a width of cloth B ultrasonic image is made up of 768 * 576 picture elements, wherein the sex of foetus position generally accounts for 50 * 50 pixel sizes, and proportion only has about 5/1000ths in entire image.In order in image, accurately to locate the sex of fetus position, at first need sex of foetus is carried out coarse positioning.According to sex of foetus position imaging characteristics, image object edge contour after cutting apart will pass through the sex of foetus position usually, and the contour line at fetus position has the high feature of degree of crook, therefore, need to extract the edge wheel profile of cutting apart the back object, and the contour line curvature value extracted, and obtain the curvature extreme point as sex of foetus position Primary Location point.
B ultrasonic image outline line drawing uses the profile tracking technique to finish after the image segmentation, uses chained list to represent by the continuous adjacent mode complete contour line.Curvature is described the degree of crook of line segment, has reflected the tendency information of line segment, and the line segment curvature value can use 11 methods or B batten method to extract.Because sex position contour line degree of crook height, pairing curvature absolute value is bigger, and the curvature value to each picture element on the contour line carries out analytical judgment subsequently, selects the bigger picture element of its mean curvature absolute value as anchor point.The scope that the Primary Location point has dwindled image recognition has improved the levels of precision of identification.
S40: judge whether doubtful sex position is positioned at the sex of foetus position, and this step is finished by sex of foetus identification module 18.
The sex position Primary Location number of spots of one width of cloth fetus image preliminary election has nothing in common with each other according to picture material is different, usually about 10 to 50, if include the sex of foetus position in the image, these Primary Location have been named a person for a particular job and one have been positioned at inside, sex of foetus position to several anchor points, and the first anchor point that therefore is positioned at non-sex position need further be excluded; If do not comprise the sex position in the image, then all first anchor points all need to be excluded.
S50: to the sex position of identification gained in addition mosaic or other shielding patterns shield, mosaic all is to be the center with the anchor point, its shape, size and pixel ash value also are adjustable.This step is finished by sex of foetus position shroud module 19.It is the center that the scope of interpolation mosaic is chosen as with identification gained sex spots localization point, and 25 picture element sizes are the square area of radius, and the pixel gray value unification in this zone is revised as 128.The image pixel gray scale at other non-sex positions remains unchanged, thereby has obtained covering the B ultrasonic image at sex of foetus position.
Compared to prior art, above-mentioned B ultrasonic equipment can be realized easily to the sex of foetus position in the B ultrasonic image Shield, and the information at other positions and original B ultrasonic image are identical, the image after processing is passed through Hardware platform is sent into B ultrasonic equipment and is replaced original image to play demonstration, and the doctor can't be from the B ultrasonic image just Really judge sex of foetus, thereby reach the purpose that illegal sex identification phenomenon is contained.
