Profile perimeter, in other application, however not excluded that the size of luminescent characters is further included perpendicular to the positive luminous word height of luminescent characters.
The luminescent characters size computing method that the present embodiment is provided, including：
Step S10：It is gray level image by luminescent characters image procossing.
In a particular application, luminescent characters image can be the design manuscript base picture of luminescent characters or arbitrarily include luminescent characters just
The image in face, for example, shooting the luminescent characters image that entity luminescent characters obtain, the luminescent characters image intercepted from other images
Deng.Since luminescent characters are not usually a complete monoblocks, there is gap, therefore, luminescent characters between each stroke of font
Image further includes background image in addition to including the image of luminescent characters in itself.
It should be appreciated that do not include the side that can also be provided through this embodiment of the luminescent characters image of background image
Method carries out size calculating.
In a particular application, in order to distinguish the image of background image and luminescent characters in itself, it is necessary to luminescent characters figure
As being pre-processed, the color of background and luminescent characters in luminescent characters image is adjusted, the color of the two is enable to be distinguished without mixed

In one embodiment, the gray value of background pixel be equal to 255 (i.e. background pixel be pure white, tonal range
A value 255 is only included, then step S30 includes：Count gray value in the gray level image [0,255) pixel number in section
Amount.
Step S40：According to the pixel quantity, gray value is calculated in the gray level image not in the gray scale model of background pixel
The gross area of all pixels in enclosing, obtains the front face area of the luminescent characters.
In a particular application, due to the size of single pixel be it is known, knowing the picture that belongs to luminescent characters
In the case of prime number amount, the front face area of luminescent characters can be calculated, i.e., the front face area of luminescent characters=single pixel area ×
Pixel quantity.
Step S50：Edge detection is carried out to the gray level image, obtains all edges of the gray level image.
In a particular application, the color of background is typically unified, therefore default background is no edge in the present embodiment
, by carrying out edge detection to gray level image, all edges finally obtained are all the edges for belonging to luminescent characters.It can basis
Actual needs selects arbitrary edge detection algorithm to carry out edge detection, for example, Laplacian algorithms, Roberts algorithms,
One kind in Sobel algorithms, log (Laplacian-Gauss) algorithm, Kirsch algorithms, Prewitt algorithms or Canny algorithms
Or a variety of combinations, other effective algorithms can also be selected certainly.
Step S60：The total length at all edges in the gray level image is calculated, obtains the luminous glyph perimeter.
It in a particular application, then can root after all edge pixels in gray level image are identified by edge detection
According to the length of side of single pixel, the length of each of the edges is calculated, all edges can be obtained by the length at all edges that add up
Total length to get to luminous glyph perimeter.
In a particular application, the image that the design manuscript base picture of usual luminescent characters or shooting obtain, is all in entity luminescent characters
Size on the basis of, it is scaled to obtain, therefore, if the size of the luminescent characters in luminescent characters image and entity luminescent characters
Size it is different, then the dimension scale relation between the luminescent characters in image and entity luminescent characters, further according to figure
The front face area of luminescent characters and profile perimeter as in, are calculated the front face area of entity luminescent characters and profile perimeter.
In one embodiment, the front face area of the luminescent characters in luminescent characters image and the positive face of entity luminescent characters are set
The ratio between product is 1：A, luminous glyph perimeter in luminescent characters image and entity shine the ratio between glyph perimeter as 1：B, then
The front face area of luminescent characters in front face area=A × luminescent characters image of entity luminescent characters, entity shine glyph perimeter
Luminous glyph perimeter in=B × luminescent characters image.
