Description of drawings
Fig. 1 is the structured flowchart of the infrared simulation image platform under the marine background of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, the infrared simulation image platform under the marine background of the present invention is based on Visual Studio 2008, utilizes C# language to write; This platform comprises that the infrared face statistical mask generates subsystem, the marine background infrared image is chosen subsystem and infrared simulation image generation subsystem; Described infrared face statistical mask generates the face template image that subsystem is used to generate different distance, the infrared database of choosing the management subsystem background image of marine background, according to user's selective extraction marine background image, the infrared simulation image generation subsystem is used for face template image and marine background image are combined.
Below in conjunction with a specific embodiment, further set forth the image generating method of this platform:
Infrared simulation image generating method under a kind of marine background, described method comprises the steps:
1) generation of face simulation template
Because the facial image that photographs is had powerful connections, so people's face need be split from background image.At first manual intercepting contains the roughly image of the image of people face part, this image is averaged again, and the image that promptly adopts neighborhood averaging adversary work point to cut is handled, and gets 3 * 3 neighborhood, as the formula (1),
(1)
Wherein
Be input picture,
Be the average image.
Select
The coordinate of middle gray-scale value maximum point
As center that will split image,
In with
For center unified intercepting size is that 9 * 9 facial image is as training image
Again to image
Do threshold process, the people face part is split from background.
Image after cutting apart is obtained by formula (2),
Wherein
Be image to be split,
Be image after cutting apart,
Be threshold value.
Then each pixel of cutting apart good image is done statistics, statistical mask generates according to the probability of training image, promptly adds up the probability of occurrence of each pixel, finally forms statistical mask.To do statistics through each pixel that formula (2) cut apart good training image, whether this picture element be belonged to people's face, as the probability of occurrence of this picture element.As the formula (3),
Wherein
For all training samples exist
The place is greater than 0 sample number,
Sum for training image.
Be the statistical mask of being asked, when
Greater than 0.5 o'clock again with all training samples
The gray scale at place is averaged, when
Be less than or equal to the gray-scale value zero setting that to put at 0.5 o'clock, obtain new images thus
, promptly
Wherein
Be k sample image.
2) the marine background image chooses
Take the image of a large amount of marine backgrounds early stage by marine real ship, when background simulation, we are just according to the difference of sea situation, weather, set up different databases, the storage associated picture, when emulation needs,, choose in such cases image as the Background of emulating image according to sea situation and the weather that experimental situation requires;
3) generation of emulating image
The generation final step of infrared simulation image, the outer image template of exactly people being blushed is embedded in the marine background image.The people who generates blushes outer image template, also needs the marine background feature of image according to reality, carries out greyscale transformation.
1) greyscale transformation
The quantitative formula of greyscale transformation is
Wherein,
The statistical mask image of behaviour face,
For the image after quantizing, right then
Indivedual points that middle gray-scale value crosses the border process, and generate final quantized result
,
With
Minimum and maximum gradation value in the behaviour face statistical mask image,
With
Be minimum in the background image and maximum gradation value [45].
2) people is blushed outer image and marine background image co-registration
The template image of the respective distances that re-quantization is good adopts maximal criterion to be fused in the background image, promptly compares the picture element of template image and background image, selects the big image of gray-scale value for use, suc as formula (7).
Wherein,
For the background image gray scale, work as a little
The gray scale of place's background is less than the analogous diagram picture point
When locating gray scale, point
The gray scale at place is exactly
,
For the final embedding people who generates blushes the extra large background infrared image of outer emulating image.
Through after the greyscale transformation, the gray scale maximal value of facial image equates with true picture, but the intensity profile of template image is too even, has big difference with true picture, therefore needs The disposal of gentle filter.
3) picture smooth treatment
After the image co-registration, more level and smooth for the edge and the background transition that make people's face, need further do Filtering Processing.Select low-pass filtering for use, the high-frequency information at reduction edge.Select for use the low pass spatial filtering method to handle at present.
The specific implementation of mean filter is:
(3.13)
Wherein,
Be the background image of embedding infrared face emulating image,
For behind the mean filter
,
For greater than zero integer,
Be the image buffer storage district, buffer memory be filtered infrared face emulating image,
Be the background image of finally finishing dealing with, wherein c has determined the size of average template, i.e. c=1,3*3 template, c=2,5*5 template.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof
