Description of drawings
Fig. 1 is the flow chart of steps of the embodiment of the invention one method.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated as follows.
Embodiment one:
As shown in Figure 1, present embodiment has been put down in writing the method that a kind of control of video that uses gesture is play, and may further comprise the steps:
S1: catch and import sequential frame image;
Said step S1 comprises that also the single-frame images to input carries out pretreated step; Said pre-service comprises format conversion, the color space conversion to image, one or more during denoising, smoothing processing, adjustment size are handled.
S2: receive the sequential frame image of input, successively every two field picture is analyzed the hand region in the recognition image and write down hand position, identify then dynamically or static gesture and obtain hand signal;
Wherein through the hand region in hand colouring information or other profile information recognition images; Through the hand exercise track, identifying this gesture is dynamic gesture, obtains hand signal according to the dynamic gesture of discerning; Through the hand shape, identifying this gesture is static gesture, obtains hand signal according to the static gesture of discerning.
S3: according to the implication of predefined hand signal, convert hand signal into the player control signal, the controls playing device is made corresponding actions.
The method that the said control of video that uses gesture is play also comprised before step S1 sets up a hand gesture location formation that is used to preserve the hand coordinate, and said hand gesture location formation is initially empty step;
Said step S2 specifically comprises: judge whether comprise hand region in this two field picture:
(I) if do not comprise hand region, and:
A) the hand gesture location formation is empty, and promptly hand is not all made action always, and not in video collection area or fail identification, need not judge gesture this moment, then directly imports the next frame image and analyze;
B) the hand gesture location formation neither sky also less than, promptly hand just shifts out the Video Detection zone, and has just made a dynamic gesture; Streak from left to right such as hand, at this moment, because comprise hand in the image of front certainly; But because hand streaks rapid speed, can not fill up whole formation, therefore judge that this gesture is a dynamic gesture; According to the continuous position of hand in the hand gesture location formation, obtain the corresponding hand signal of this dynamic gesture;
C) the hand gesture location formation is for full, and promptly staff has been accomplished a static gesture, and the consecutive numbers two field picture has detected hand position and shows; Staff is through accomplished a static gesture for a long time; This width of cloth image detection is left to hand, judges that then static gesture accomplishes, and empties the hand gesture location formation; Open gesture identification module and the interface of playing module time, input next frame image is analyzed;
(II) if comprise hand region, then hand position is recorded in the hand gesture location formation, judge again whether formation is full:
A) if formation is full; Then judge and accomplished a static gesture,, obtain the pairing hand signal of static gesture according to the hand shape; Close the interface between gesture identification module and the playing module then; Promptly before hand shifts out surveyed area, do not send control signal to player, the purpose of doing like this is the repeatedly identification that prevents an order;
B) if formation is discontented, can't judge that gesture is static gesture or dynamic gesture this moment, therefore need not discern, and input next frame image is analyzed.
