Mode one, according to the size of the subgraph, determine the size of dynamic window in the current video image.
Optionally, according to the corresponding relationship of subgraph size and zoom factor, the corresponding scaling system of the subgraph is determined
Number；Size by the product of the corresponding zoom factor of the subgraph and the size of the subgraph, as the dynamic window.
Wherein, subgraph size is the number of the pixel column number that subgraph occupies and the pixel column that subgraph occupies；
For example, subgraph size is 160*90, indicate that the pixel column number that subgraph occupies is 160, the pixel column of occupancy
Number be 90.
In implementation, it is previously stored with the corresponding relationship of subgraph size and zoom factor；
Optionally, which can be tables of data.
After determining subgraph in current video image, by searching for tables of data, determine that subgraph size is corresponding
Zooming parameter, using subgraph size and the product of zooming parameter as the size of dynamic window；
For example, subgraph is determined in current video image, it is big according to subgraph when the size of subgraph is 160*90
It is small when determining that the corresponding zoom factor of the subgraph is k1 with the corresponding relationship of zoom factor, by the number of pixels and contracting of subgraph
Size of the product as dynamic window of coefficient k 1 is put, that is, determines that the number for the pixel column that dynamic window occupies is 160*k1, accounts for
The number of pixel column is 90*k1.
It should be noted that hiding the dynamic window when the size of subgraph is greater than preset threshold；
For example, the corresponding zooming parameter of subgraph size is 0 when the size of subgraph is greater than preset threshold.
Mode two, the first instruction for receiving the size for being used to indicate dynamic window that user inputs, and according to the first instruction
Determine the size of dynamic window in current video image.

Mode one, according to the position of current video image neutron image and the position of previous frame video image neutron image
It sets, determines the position of dynamic window in current video image.
Optionally, according to the position of the current video image neutron image and previous frame video image neutron image
Position, determine subgraph location variation；It is closed according to subgraph location variation is corresponding with dynamic window location variation
System, determines the corresponding dynamic window location variation of the subgraph location variation；According to the dynamic window before described
Position and the dynamic window location variation in one frame video image, determine the dynamic window in the current video figure
Position as in.
Wherein, subgraph location variation includes position moving direction and position moving distance；
Dynamic window location variation includes position moving direction and position moving distance.
The corresponding relationship of subgraph location variation and dynamic window location variation is preset.
When the embodiment of the present invention determines the position of dynamic window, respectively obtain current video image neutron image position,
The position of previous frame video image neutron image, and calculate subgraph location variation；By searching for subgraph location variation
With the corresponding relationship of dynamic window location variation, the corresponding dynamic window location variation of subgraph location variation is determined,
It is adjusted according to position of the determining dynamic window location variation to dynamic window in previous frame video image, to obtain
Position of the dynamic window in current video image.
In implementation, subgraph location variation can be calculated according to the central pixel point position of subgraph, and according to dynamic
The center position of state window determines dynamic window location variation.
It should be noted that when position of the target object in two frame video image of front and back does not change, correspondingly,
Position of the subgraph in two frame video image of front and back does not also change, then subgraph location variation is zero, and
When subgraph location variation is zero, corresponding dynamic window location variation is set as zero；That is, in the position of subgraph
It sets when not changing, the position of dynamic window does not also change；
For example, the position of dynamic window and the position of subgraph in previous frame video image as shown in Figure 5, previous
The position of frame video image neutron image is position 1, and the position of dynamic window is position A；In current video image, subgraph
Position also be located at position 1, then subgraph location variation be 0, at this time determine dynamic window location variation be 0, be not required to
Adjust the position of dynamic window.
It should be noted that picture position variable quantity and dynamic window position become the embodiment of the present invention through reasonable settings
The corresponding relationship of change amount may be implemented dynamic window and be changed according to preset motion track；Wherein, the preset moving rail
Mark can be elliptical path.
Since the embodiment of the present invention is that influence user is avoided to check target object by current video image, also need
Guarantee that the position of dynamic window is different from position of the subgraph in current video image；It, can be in setting subgraph in implementation
It is realized when the corresponding relationship of location variation and dynamic window location variation.
Mode two, the second instruction for receiving the position for being used to indicate the dynamic window that user inputs, and according to described
Second instruction determines the position of dynamic window described in the current video image.
Wherein, user passes through the second instruction of the interface UI input；
Specifically, the second instruction is that user passes through the touch operation carried out in the display interface；
For example, user pulls dynamic window in the display interface, position of the dynamic window in current video image is adjusted.
Alternatively, the data of the position for the expression dynamic window that the input window that the second instruction is display interface is arranged；
One input window, the expression dynamic window that user needs to be arranged by input window input are set in the display interface
The data of mouth position；For example, user inputs the pixel coordinate value in the dynamic window upper left corner by input window, and input is moved
The pixel coordinate value in the state window lower right corner.
Alternatively, the second instruction is the instruction that user is inputted by external equipment；For example, when showing equipment is television set,
User adjusts position of the dynamic window in current video image by remote controler.
It can be by the mutability of target object when identifying target object from current video image due to the embodiment of the present invention
Feature, but the variable feature of target object is easy to happen variation；Such as the dress ornament of target object changes；In order to improve
The efficiency for identifying target object, needs to constantly update the variable feature of target object.
Optionally, after identifying target object, the variable feature of target object is extracted；In the target pair extracted
When the variable feature difference of the target object of the variable feature and storage of elephant, the easy of the target object extracted is used
Become the variable feature of the target object of feature replacement storage.
When the variable feature of target object changes, due to target object fixed character be it is changeless, because
This, can identify the target object in current video image according to the fixed character of target object, and extract target object
Variable feature uses the newest variable feature extracted in variable feature and the variable feature difference of the target object of storage
Replace the variable feature of the target object of storage；
For example, extracting the variable feature of target object after identifying target object in current video image；Assuming that mentioning
The dress ornament color for the target object got is red, and the dress ornament color of the target object stored is blue；Determine newest extraction
The dress ornament color of the target object arrived and the dress ornament color of the target object of storage are different, then by the dress ornament of the target object of storage
Color replaces with red.
Since the embodiment of the present invention from current video image when identifying target object, according to the fixed special of target object
Variable feature of seeking peace is identified, accurately and quickly identifies target object so as to basis；For example, watching body in user
When educating match, each player has unique number, and the unique number is the variable feature of player, and according to the volume
Number it can quickly recognize target object；
The embodiment of the present invention can deposit newest variable feature after the variable feature of target object changes
