In the embodiment of the present application, if desired in the original image foreground target carry out Local treatment, need by
Affiliated foreground target is split from original image, on the basis of embodiment shown in Fig. 2, is already available to the foreground
The detection block of target, since the image in detection block is largely foreground target image, so, it can be based in the detection block
Image segmentation described in foreground target.
Step S302, based on the shade of gray of the image in the detection block, before identifying in the image in the detection block
The boundary of scape target obtains foreground target contour line.
In the embodiment of the present application, the boundary of foreground target is to discriminate between the important evidence of foreground target and background image, and
In general, surrounding's gray-value variation rate of foreground target boundary point is higher, therefore, before being identified by the shade of gray of image
The boundary of scape target obtains foreground target contour line.However, foreground target contour line can also have a problem that is：In image
Actually boundary, however since graded unobvious may would not generate contour line；Alternatively, actually not boundary,
Contour line is generated inside foreground target since the gray-value variation inside foreground target is more apparent.So generating at this time
Foreground target contour line be not be real foreground target contour line.
Step S303 obtains gray threshold sequence, and by each gray threshold in the gray threshold sequence to institute
The image stated in detection block carries out binary conversion treatment, obtains gray scale foreground target image sequence.

Gray threshold sequence is obtained afterwards, and two are carried out to the image in the detection block by each gray threshold in gray threshold sequence
Value is handled, so that it may to obtain gray scale foreground target image sequence, in these gray scale foreground target image sequences, can there is one
Gray scale foreground target image, this gray scale foreground target image can rough expression foreground target regions.
In gray threshold sequence, if threshold value setting is suitable, the foreground target region can be obtained.However, practical
In, foreground target and background image are separated to suitable threshold value it is difficult to accurately choose, even if choosing to suitable
Threshold value can inevitably have pixel identical with the gray value of the pixel in foreground target in background image.
By the analysis of step S302 and step S303 it is found that in fact, the method for the method and shade of gray of binaryzation
Can there be certain defect, the result of acquisition is not highly precisely result.It is accurate as a result, this Shen in order to obtain
Please embodiment the method for the method of binaryzation and shade of gray is combined together acquisition foreground target, such as step S304 is to walking
The content of rapid S305 descriptions.
Step S304 is obtained with the foreground target shape matching degree most from the gray scale foreground target image sequence
High gray scale foreground target image.

How the regional extent of scape target obtains closest to the true regional extent of foreground target from gray scale foreground target image sequence
Image closest to the true regional extent of foreground target can be obtained from the gray scale foreground target image sequence and institute
State the highest gray scale foreground target image of foreground target shape matching degree.Matching degree can pass through binarization method and gray scale ladder
The registration in the region for the foreground target that degree method obtains respectively is as matching degree.In each gray scale foreground target image sequence
Target area can temporarily regard foreground target region as, the region in foreground target contour line that shade of gray method obtains
Foreground target region can temporarily be regarded as, find the highest gray scale of foreground target area coincidence degree obtained with shade of gray method
Foreground target image.Before foreground target region in this gray scale foreground target image comparatively can be than more actually indicating
Scape target area, but nor completely accurate foreground target region.
Step S305, by with the highest gray scale foreground target image of the matching degree of the foreground target contour line with it is described before
The fusion of scape target profile curve generates continuous foreground target region, the figure in the foreground target region described in the original image
As being foreground target.
In the embodiment of the present application, the foreground in the highest gray scale foreground target image of matching degree actually no matter obtained
The foreground target region that the foreground target contour line that target area or shade of gray method obtain indicates all can not accurately retouch
State foreground target region, however, it is possible to by with the highest gray scale foreground target image of the matching degree of the foreground target contour line
It is merged with the foreground target contour line and generates continuous foreground target region, shade of gray is abandoned by binary image and is obtained
Inaccurate part, the foreground target contour line obtained by shade of gray method abandon ash in the foreground target contour line obtained
Part inaccurate in foreground target image is spent, continuous foreground target region is obtained after fusion, the foreground mesh obtained after fusion
It is not real foreground target image to mark region, because being merged by gray level image after binaryzation and contour line, institute
With the foreground target region expression of acquisition is coordinate of the foreground target in the original image.Before in original image
Image in scape target area is only foreground target.
It should be understood that the size of the serial number of each step is not meant that the order of the execution order in above-described embodiment, each process
Execution sequence should be determined by its function and internal logic, the implementation process without coping with the embodiment of the present application constitutes any limit
