Abstract
The invention discloses the methods that dynamic adjusts image coding region, comprising the following steps: step (1): obtaining picture depth situation of change；Step (2): situation of change is mapped to entire picture, obtains the coding parameter in each region；Step (3): for the region not encoded, polishing is carried out；Step (4): exports coding is as a result, the present invention can accelerate coding rate, raising code efficiency；The data volume after coding is reduced, convenient for saving and transmitting.
Description
Technical field
The present invention relates to field of image processings, the specially method of dynamic adjustment image coding region.
Background technique
Current image coding is all completely to encode to entire picture, but under the scene of part, draw to entire
Face is encoded, and it is bigger than normal to will lead to data volume, is unfavorable for transmitting and be saved.The time spent on coding simultaneously is also partially long.
Summary of the invention
The purpose of the present invention is to provide the method that dynamic adjusts image coding region, the present invention can accelerate coding speed
Degree improves code efficiency；The data volume after coding is reduced, convenient for saving and transmitting.
To achieve the above object, the invention provides the following technical scheme: the following steps are included:
Step (1): picture depth situation of change is obtained；
Step (2): situation of change is mapped to entire picture, obtains the coding parameter in each region；
Step (3): for the region not encoded, polishing is carried out；
Step (4): exports coding result.
Preferably, the step (3) specifically includes: judging whether to fill uncoded region, if otherwise direct exports coding
As a result；If then carrying out polishing for the region not encoded.
Preferably, in the step (1): being detected using depth of the accessory external equipment to picture, outside the auxiliary
Portion's equipment is 3D structure light and TOF.
Preferably, the step (1) further include: compare the situation of change of picture depth, and record.
Compared with prior art, beneficial effects of the present invention are as follows: the present invention can accelerate coding rate, improve coding
Efficiency；The data volume after coding is reduced, convenient for saving and transmitting.
Detailed description of the invention
Fig. 1 is workflow schematic diagram of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that term " on ", "lower", "inner", "outside" " front end ", " rear end ",
The orientation or positional relationship of the instructions such as " both ends ", " one end ", " other end " is to be based on the orientation or positional relationship shown in the drawings, only
It is that for the convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning must have specifically
Orientation is constructed and operated in a specific orientation, therefore is not considered as limiting the invention.In addition, term " first ", " the
Two " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation " " is set
Be equipped with ", " connection " etc., shall be understood in a broad sense, such as " connection ", may be a fixed connection, may be a detachable connection or one
Connect to body；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, it can also be indirect by intermediary
It is connected, can be the connection inside two elements.For the ordinary skill in the art, on being understood with concrete condition
State the concrete meaning of term in the present invention.
The present invention provides the method that dynamic adjusts image coding region, comprising the following steps:
Step (1): picture depth situation of change is obtained, wherein visiting using depth of the accessory external equipment to picture
It surveys, the accessory external equipment is 3D structure light and TOF；
Step (2): situation of change is mapped to entire picture, obtains the coding parameter in each region；
Step (3): for the region not encoded, carrying out polishing, wherein specifically include judge whether to fill it is uncoded
Region, if otherwise direct exports coding result；If then carrying out polishing for the region not encoded；
Step (4): exports coding result.
Embodiment 1
Shown in referring to Fig.1, the method that dynamic adjusts image coding region utilizes accessory external equipment (such as 3D structure light
And TOF) depth of picture is detected；It so as to compare the situation of change of picture depth, and records, according to depth
Situation of change, to different zones use different resolution ratio.Hence for the unconverted region of picture depth, or even without
Coding；The present invention can accelerate coding rate, improve code efficiency；The data volume after coding is reduced, convenient for saving and passing
It is defeated.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
