Processing unit 13 is in order to capture a filmstrip 22 of film 20, and wherein filmstrip 22 can comprise several continuous pictures.Processing unit 13 is more used to, in one first picture of these continuous pictures, define the position 40 of at least one first object, and in one second picture of these continuous pictures, defines the position 42 of this at least one first object.At least one object described in the present embodiment can be considered one or more object.Processing unit 13 is also in order to be positioned at the position 40 of this first picture according to this at least one first object and to be positioned at the position 42 of this second picture, judge the position in each picture of this at least one first object between this first picture and this second picture, use this at least one first object of estimation from this first picture to the motion track of this second picture.
For ease of illustrating, the processing unit 13 of the present embodiment can comprise film cutting module 131, object and define module 133 and an object tracking module 135.In other embodiments, processing unit 13 also can be only single processor, and performs the corresponding operation of above-mentioned modules.
As shown in Figure 1, after film supplier unit 11 supplies film 20 to processing unit 13, first processing unit 13 captures the filmstrip 22 of film 20 by film cutting module 131.The object of film cutting module 131 is to have at least one common objects in several continuous pictures that the filmstrip 22 guaranteeing to capture comprises.Therefore, filmstrip 22 can be whole section of film 20, also can be arbitrary section of fragment in film 20.
For example, whether film cutting module 131 can switch according to the picture camera lens of shooting film 20, judges that whether picture is continuous.If picture is discontinuous, then film cutting module 131 can cut film 20, and captures the filmstrip 22 comprising several continuous pictures.In other embodiments, processing unit 13 also can not have film cutting module 131, and direct film 20 to the object that transmits of film supplier unit 11 defines module 133.
When electronic installation 1 does not comprise user's interface unit 15, after the film cutting module 131 of processing unit 13 captures the filmstrip 22 of film 20, the object of processing unit 13 defines module 133 and in order to define the position 40 of at least one first object at this first picture of these continuous pictures, and can define the position 42 of this at least one first object at this second picture of these continuous pictures.
When electronic installation 1 comprises user's interface unit 15, the object of processing unit 13 defines module 133 and can input 60 according to the user from user's interface unit 15, defines the position 40 of this at least one first object and in this second picture, define the position 42 of this at least one first object in this first picture.For example, user is by a touch screen, a slide-mouse, a keyboard or various input media (not illustrating), and in this first picture and this second picture, this at least one object selected by manual frame.Then, user's interface unit 15 inputs 60 by producing user according to user's scope that institute's frame selects in this first picture and this second picture.Then, the object of processing unit 13 defines module 133 and will input 60 according to user, defines the position 40 of this at least one first object and in this second picture, define the position 42 of this at least one first object in this first picture.
After the object of processing unit 13 defines the position 40 that module 133 defines this at least one first object in this first picture and the position 42 defining this at least one first object in this second picture, the object tracking module 135 of processing unit 13 can in order to be arranged in the position 40 of this first picture according to this at least one first object and to be positioned at the position 42 of this second picture, judge the position in each picture of this at least one first object between this first picture and this second picture, use this at least one first object of estimation from this first picture to the motion track of this second picture.
Below using Fig. 2 and Fig. 3 as a demonstration example, the above-mentioned running that object defines module 133 and object tracking module 135 will be further illustrated.Fig. 2 is a schematic diagram of filmstrip 22, and Fig. 3 is a running schematic diagram of object tracking module 135.
As shown in Figure 2, filmstrip 22 comprises several continuous pictures.For convenience of explanation, suppose that the first picture F1 is the start picture in these continuous pictures of comprising of filmstrip 22, and the end picture in these continuous pictures that the second picture F2 is filmstrip 22 to be comprised.In other embodiments, the first picture F1 and the second picture F2 can also be wantonly two the non-adjacent pictures in these continuous pictures of comprising of filmstrip 22.
The object of processing unit 13 defines module 133 and first judges whether the first picture F1 and the second picture F2 occurs identical object.Because the first object X1(circular object all appears in the first picture F1 and the second picture F2) time, therefore the object of processing unit 13 defines module 133 is positioned at the position 40 of the first picture F1 by defining the first object X1 and is positioned at the position 42 of the second picture F2.Afterwards, the object tracking module 135 of processing unit 13, by being positioned at the position 40 of the first picture F1 according to the first object X1 and being positioned at the position 42 of the second picture F2, judges the position in each picture of the first object X1 between the first picture F1 and the second picture F2.
If multiple first object X1 appears at the first picture F1 and the second picture F2 simultaneously, the object of processing unit 13 defines module 133 and synchronously can define several first object X1 and be positioned at several positions 40 of the first picture F1 and be positioned at several positions 42 of the second picture F2, and the object tracking module 135 of processing unit 13 will be positioned at these positions 40 of the first picture F1 and be positioned at these positions 42 of the second picture F2 according to several first object X1, judge the position respectively in each picture of this first object X1 between the first picture F1 and the second picture F2.
In other embodiments, even continuous pictures, in filmstrip 22, some object may not appear at the first picture F1, but appears at the second picture F2; Or some object may appear at the first picture F1, but do not appear at the second picture F2.The former is the second object X2(triangle object as shown in Figure 2 still), and the latter is just as the square object of the third body X3(shown in Fig. 2).The quantity of the second object X2 and third body X3 can be one or several.
Only appear at the second picture F2 due to the second object X2 and do not appear at the first picture F1, therefore the second object X2 may start to occur by a certain picture between the first picture F1 to the second picture F2, and continue to occur until the second picture F2.Therefore, the object of processing unit 13 defines module 133 more in order to define the position 43 of the second object X2 in the second picture F2; And a selected 3rd picture F3 in picture between the first picture F1 and the second picture F2, in the 3rd picture F3, then define the position 44 of the second object X2.Then, the object tracking module 135 of processing unit 13 is more in order to be arranged in the position 43 of the second picture F2 and to be positioned at the position 44 of the 3rd picture F3 according to the second object X2, judge the position in each picture of the second object X2 between the second picture F2 and the 3rd picture F3, use estimation second object X2 from the 3rd picture F3 to the motion track of the second picture F2.
Similarly, only appear at the first picture F1 due to third body X3 and do not appear at the second picture F2, therefore third body X3 may disappear by a certain picture between the first picture F1 to the second picture F2, and continued depletion is until the second picture F2.Therefore, the object of processing unit 13 defines module 133 more in order to define the position 45 of third body X3 in the first picture F1; And a selected 3rd picture F3 in picture between the first picture F1 and the second picture F2, in the 3rd picture F3, then define the position 46 of third body X3.Then, the object tracking module 135 of processing unit 13 is more in order to be arranged in the position 45 of the first picture F1 and to be positioned at the position 46 of the 3rd picture F3 according to third body X3, judge the position in each picture of third body X3 between the first picture F1 and the 3rd picture F3, use estimation third body X3 from the first picture F1 to the motion track of the 3rd picture F3.
When to there is the second object X2 and third body X3 simultaneously, the object of processing unit 13 defines module 133 can select two different the 3rd picture F3 respectively to define the position 44,46 of the second object X2 and third body X3 respectively from the picture between the first picture F1 from the second picture F2, only can also select identical a 3rd picture F3 to define the position 44,46 of the second object X2 and third body X3.In addition, from the picture between the first picture F1 and the second picture F2, select the rule of the 3rd picture F3, thumb rule, dichotomy can be adopted then or other known methods.For example, the object of processing unit 13 defines module 133 and can adopt dichotomy and select that picture of centre in the picture between the first picture F1 and the second picture F2 as the 3rd picture F3.In other embodiments, also the 3rd picture F3 can be selected by user's interface unit 15 by user from the picture between the first picture F1 and the second picture F2.
Except the situation of above-mentioned second object X2 and third body X3, some object may appear in the picture between the first picture F1 and the second picture F2, and disappears in the picture between the first picture F1 and the second picture F2.In other words, these objects do not come across in the first picture F1 and do not come across in the second picture F2 yet.But known based on above-mentioned disclosure, the object of processing unit 13 defines module 133 and still can effectively estimate the motion track these objects with object tracking module 135.
For example, suppose that the object of processing unit 13 defines module 133 in the 3rd picture F3, defines one the 4th object (not illustrating), and the 4th object does not come across in the first picture F1 and does not come across in the second picture F2 yet.Now, the object of processing unit 13 defines module 133 and can select one the 4th picture (not illustrating) in the picture between the first picture F1 and the 3rd picture F3, or selected one the 5th picture (not illustrating) in picture between the 3rd picture F3 and the second picture F2, in the 4th picture and/or the 5th picture, then define the position of the 4th object.Similarly, the object tracking module 135 of processing unit 13 can be positioned at the position of the 4th picture according to the 4th object and be positioned at the position of the 3rd picture F3, judge the position in each picture of the 4th object between the 4th picture and the 3rd picture F3, use estimation the 4th object from the 4th picture to the motion track of the 3rd picture F3.Or, the object tracking module 135 of processing unit 13 can be positioned at the position of the 3rd picture F3 according to the 4th object and be positioned at the position of the 5th picture, judge the position in each picture of the 4th object between the 3rd picture F3 and the 5th picture, use estimation the 4th object from the 3rd picture F3 to the motion track of the 5th picture.
In other embodiments, the object of processing unit 13 defines module 133 and also can determine several specific picture (not illustrating) between the first picture F1 and the second picture F2.For example, object defines module 133 can from the first picture F1, equally spaced at interval of N number of picture (N is positive integer), just determines a specific picture until the second picture F2.Or object defines module 133 also can determine these specific pictures at random between the first picture F1 and the second picture F2.When after these specific pictures of decision, object defines module 133 from two adjacent pictures the first picture F1, the second picture F2 and these specific pictures, can define the position of a same object respectively.Then, the object tracking module 135 of processing unit 13 according to this same object these positions in this two adjacent pictures, can judge the position in each picture of this same object between this two adjacent pictures.

Suppose to also have three pictures between the first picture F1 and the second picture F2, object tracking module 135 can utilize box frame B1 to define the position 40 of the first object X1 in the first picture F1, then various known film object tracking technology is adopted, carry out forward tracking to the position of the first object X1 in all the other four pictures, wherein the estimation position of the first object X1 in all the other four pictures represents with box frame B2 respectively.Known film object tracking technology can be but be not limited to: average displacement algorithm (Mean Shift Algorithm), continuously adaptive average displacement algorithm (Continuously Adaptive Mean Shift Algorithm), overall tracking algorithm (Ensemble Tracking Algorithm) etc.
Object tracking module 135 also can for estimation position calculation one weighted value of the first object X1 in each picture.For example, the weighted value of the first position of object X1 in each picture can be sequentially 1,0.75,0.5,0.25,0.It is more complete that weighted value higher expression box frame B1, B2 contain the first object X1, and the estimation position of the first object X1 in each picture is more accurate.
Similarly, object tracking module 135 can utilize box frame B1 to define the position 42 of the first object X1 in the second picture F2, then various known film object tracking technology is adopted, carry out backward tracing to the position of the first object X1 in all the other four pictures, wherein the estimation position of the first object X1 in all the other four pictures represents with box frame B2 equally respectively.Object tracking module 135 equally can for estimation position calculation one weighted value of the first object X1 in each picture.For example, the weighted value of the first position of object X1 in each picture can be sequentially 0,0.25,0.5,0.75,1.
Finally, to follow the trail of according to forward and backward tracing calculates these weighted values for the first position of object X1 in each picture and to be averaged weighted calculation, to judge that the first object X1 is arranged in the position of each picture, and then estimation the first object X1 is from the first picture F1 to the motion track of the second picture F2.Based on identical determination methods, the motion track of the second object X2 and the second object X3 can be estimated.
In other embodiments, object tracking module 135 also can be positioned at the position 40 of the first picture F1 according to the first object X1 and be positioned at the position 42 of the second picture F2, adopt various known interpolation algorithm, judge the position in each picture of the first object X1 between the first picture F1 and the second picture F2, use estimation first object X1 from the first picture F1 to the motion track of the second picture F2.
