Referring now to Fig. 3, the operation of rectangle frame generating means is described in conjunction with the example of specific portrait photo.
According to top description to the match device, learnt and can come in the match portrait photo to be figure 3 illustrates this ellipse with an ellipse by the person's of taking pictures head, suppose elliptical center be (x0, y0).It should be understood that with regard to the relative position among Fig. 3 oval trunnion axis (or minor axis) defines by the width of the person's of taking pictures head, the left and right end points of trunnion axis is represented respectively by the person's of taking pictures left cheek and right cheek; Oval vertical axes (or major axis) defines by the height of the person's of taking pictures head, and the upper and lower end points of vertical axes is represented respectively by the person's of taking pictures the crown and lower jaw.The R line that Fig. 3 also shows the A line that is positioned at oval top horizontal level, the B line that is positioned at oval bottom horizontal level, is positioned at the L line of oval left end vertical position and is positioned at oval right-hand member vertical position.In the following description, suppose the distance between L line and the R line, promptly the length of ellipse short shaft is a pixel; Distance between A line and the B line, promptly the length of transverse is the b pixel.In Fig. 3, also show by the horizontal level of the person's of taking pictures eyes, in the following description, suppose that the distance between C line and the A line is the c pixel with the C line.Need to prove, the eyes position is had under the situation of specific requirement at photo, be necessary to determine the position of the quilt person of taking pictures eyes, this can utilize the known method of this area to realize, for example, the middle and upper part of facial zone detects the position of eyes by template matching algorithm in portrait images, and then obtains the position and the centre coordinate of pupil on the image of each eye with histogrammic method, thereby determines the horizontal level of eyes.Be used for determining that the device of eyes position can be computer program module that moves or the hardware module that realizes separately in the CPU outside on CPU.
In conjunction with above-mentioned fitted ellipse the process of utilizing the rectangle frame generating means to generate rectangle frame is described now.
In general, certificate photo has some common specifications parameters, for example the width of photo, highly, the distance to the distance of photo corresponding edge, the crown to the photo top about cheek, lower jaw distance or the like to the distance of photo bottom, eyes to the photo top.
At first, determine the width and the height of rectangle frame according to the relevant parameter of the length of one of the minor axis of ellipse and major axis and photo.In one embodiment, can determine the width of rectangle frame and highly to the predetermined distance of photo both sides or by the Rack of the person's of taking pictures cheek according to the Rack of the length of regulation the ratio of width to height of photo, oval trunnion axis, photo and by the person of taking pictures left and right sides cheek.In another embodiment, can be according to length, the specified altitude of photo and other parameter of photo of regulation the ratio of width to height of photo, oval vertical axes, for example by the person's of taking pictures the crown to the predetermined distance of photo top edge, by the person's of taking pictures lower jaw to the predetermined distance of photo lower limb or by the person's of taking pictures eyes to the predetermined distance of photo top edge etc., determine the width of rectangle frame and highly.In other embodiments of the invention, can determine the width and the height of rectangle frame according to other the combination of photo parameter.
Then, on image display area according to determined rectangle frame width with highly draw rectangle frame.Be understandable that, can make in the width of rectangle frame and two axles that short transverse is parallel to described ellipse respectively one and another when drawing rectangle.In Fig. 3, the Width of rectangle frame is parallel to oval trunnion axis, and its short transverse is parallel to oval vertical axes.
At last, determine the position of described rectangle frame based on the related parameter that has of photo.Photo have related parameter for example, but be not limited to, by the Rack of the person of taking pictures cheek, by the person's of taking pictures left cheek to the predetermined distance of photo left hand edge, by the person's of taking pictures right cheek to the predetermined distance of photo right hand edge, by the person's of taking pictures the crown to the predetermined distance of photo top edge, the quilt person's of taking pictures lower jaw to the photo lower limb predetermined distance or the quilt person's of taking pictures eyes to the predetermined distance of photo top edge etc.
In a particular embodiment, suppose that certificate photo regulation digital photos size is wide for the W pixel, H pixel height; Be D1 ± d1 pixel apart from the photo both sides about cheek; The crown is no more than the H2 pixel apart from the photo top; And eyes are H1 ± h1 pixel apart from the photo top.Fig. 3 has schematically shown the rectangle that constitutes rectangle frame.In this particular example, can and be determined that to the distance D 1 ± d1 of photo both sides the width of rectangle frame is a*W/ (W-2*D1) pixel, highly is a*H/ (W-2*D1) pixel about the person's of taking pictures cheek according to Rack W, the specified altitude H of the length a of the trunnion axis of ellipse, photo, thereby the ratio that obtains a width and height equals the rectangle of ratio of the specified altitude of the Rack of photo and photo.Then, preferably, (x0 is that rectangle frame is drawn at the center y0) with the center of ellipse.Then, by along the center of the vertical axes translation rectangle frame of ellipse and based on by the person's of taking pictures the crown to the predetermined distance and the quilt person's of taking pictures the eyes of photo top edge are determined described rectangle frame to the predetermined distance of photo top edge position, if supposition rectangle frame center is (x0, y0+ Δ y), then the coordinate of the short transverse at rectangle frame center is adjusted to and makes: for the distance (be A line distance to rectangle top margin) of summit on the ellipse to the rectangle frame top margin, relational expression (1) H/2-b* (W-2D1)/(2*a)+Δ y* (W-2*D1)/a＜H2 sets up; And for by the distance (be C line distance to rectangle top margin) of the position of the person of taking pictures eyes to the rectangle frame top margin, when relational expression (2) H1-h1≤H/2+ (2*c-b) * (W-2*D1)/(2*a)+Δ y* (W-2*D1)/a≤H1+h1 sets up, the position of rectangle frame meets the demands, and can determine the position of rectangle frame thus.Should be noted that, in this particular example, rectangle frame is drawn in any position that can be in image display area, also will be based on by the distance (L line and R line branch be clipped to the distance on the rectangle left side and the right) of the person of taking pictures left and right sides cheek to the photo both sides when just next determining the position of rectangle frame.
Dash area region representation among Fig. 3 is dropped in this zone with respect to rectangle frame by the person's of taking pictures head and all satisfies condition, and just the position for rectangle frame provides certain margin of tolerance.For example, in this embodiment, requiring about cheek apart from the photo both sides is D1 ± d1 pixel, but then the position of rectangle frame has the excursion of 2d1 pixel in the horizontal direction.Be understandable that, above-mentioned relation formula (1) and (2) but embodied the excursion of the position in the vertical direction of rectangle frame.
When in addition, the size of determining rectangle frame is with the position based on parameter can be different as the case may be.For example, in another embodiment, can be based on the position of being determined rectangle frame by the person's of taking pictures lower jaw to the predetermined distance of photo bottom.In addition, the photo parameter be not limited to above-mentioned those, according to circumstances can be other parameter.
More specifically, suppose a kind of portrait photo require as follows:
1. photo is level (W) 300 pixels, vertically (H) 400 pixels;
2. edge, the crown is no more than 30 pixels far from photo top (H2);
3. lower jaw is no more than 30 pixels apart from the photo bottom;
4. (D1 ± d1) is 30 ± 5 pixels apart from the photo both sides about cheek;
5. two are positioned at same horizontal line, and (H1 ± h1) is 100 ± 5 pixels on the distance picture top.
As mentioned above, can (x0 y0) be the center, draws a width and is a*300/ (300-30*2) pixel, highly is the rectangle frame of a*300/ (300-30*2) * (400/300) pixel with the center of ellipse.Determine the position of rectangle frame then based on following condition: the A line to the distance of rectangle top margin be no more than 30 pixels, B linear distance rectangle base be no more than 30 pixels and C line to the distance of rectangle top margin in the scope of [95,105] pixel.In this process, preferably by in that (x0 chooses in the scope of y0 ± h) a bit and comes the translation rectangle frame to determine the appropriate location of rectangle frame as the rectangle frame center, and wherein h can value b/2.
In addition, in this example, because the distance that arrives the photo both sides about cheek is [25,35] all meet the demands in the scope of pixel, so position in the horizontal direction, rectangle frame center can oval abscissa x0 be that the center changes in certain scope, in Fig. 3, this scope is embodied by the dash area zone that schematically marks on L line and the R line.Similarly, the center of rectangle frame neither be unique in the position of vertical direction, but the excursion of position is by the common decision in dash area zone that schematically marks on A line, B line and the C line among Fig. 3.
After generating rectangle frame, utilizing Scissoring device is that frame carries out cutting to portrait images with the rectangle frame.And ((300-30*2)/a) carries out convergent-divergent so that image reaches the size of 300 * 400 pixels with identical zoom factor with the wide of images cut (be rectangle frame in image) and height can to utilize device for zooming.The photo that like this, finally obtains will satisfy above-mentioned each requirement.
To different portrait photos, the numerical value of parameter can be different, but principle is the same.
The description intention of front only is illustrative, rather than in order to limit the present invention, numerous other alternative embodiments according to the present invention are obvious for a person skilled in the art.Those of ordinary skill in the art can be to here form and the details of disclosed embodiment are carried out many variations.For example, in the superincumbent description, for simplicity, the have related parameter and the relevant variable of photo have adopted the absolute figure representation, but be understandable that, the absolute figure representation of photo parameter and relevant variable can change into relative value representation of equal value, for example, and the Rack of photo and can be changed into the ratio of the Rack of the predetermined distance that arrived the photo both sides about the person's of taking pictures cheek and photo to the predetermined distance of photo both sides about the person's of taking pictures cheek.More specifically, for example, in an above-mentioned embodiment, the width of rectangle frame is a*W/ (W-2*D1) pixel, highly for a*H/ (W-2*D1) pixel, if they are changed into width that the relative value representation obtains rectangle frame is a* (W/H)/(W/H-2* (D1/W) * (W/H)) pixel, highly is a/ (W/H-2* (D1/W) * (W/H)) pixel, substantially be of equal value before transforming, wherein (W/H) is the ratio of width to height of photo, (D1/W) for being arrived the distance of photo left and right edges and the ratio of photo width about the person's of taking pictures cheek.Therefore, though disclose some preferred embodiment of the present invention here, it will be apparent to those skilled in the art that: the various changes that may make on form of the present invention and details do not have to break away from the shown the spirit and scope of the present invention of entire scope as following claim.
