Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, in one embodiment, a kind of picture method for splitting, comprises the following steps:
Step S10, obtains original image.
The picture resource and dimension information etc. of original image can be obtained.Dimension information is the ranks quantity information of the pixel forming picture, and such as original image is of a size of 1024 × 768, then represent that this original image is made up of 1024 row, 768 row pixels.
Step S20, splits original image according to pre-set dimension, obtains local picture.
The size of original image is about the integral multiple of the size of local picture.
In one embodiment, doubly, original image wide is about the M power of wide 2 of local picture doubly to the Nth power being about 2 of length for local picture of original image, and M, N are natural number, but are 0 when M, N are different.That is, when splitting original image, original image can be separated in half, repeat to be separated in half splitting the local picture obtained, presetting secondary fractionation until complete.For rotational symmetry or centrosymmetric picture, split according to above-described embodiment, more easily obtain rotational symmetry or centrosymmetric local picture, contribute to original image to split into the local picture multiple local picture comprising redundancy, the redundancy picture that the local picture split comprises is more, and the local picture of reservation is also fewer.
Step S30, removes the local picture of redundancy in the picture of local.
In one embodiment, the local picture of redundancy is can by other local picture beyond self through local picture that geometric transformation obtains.
Concrete, the local picture of redundancy is can by any pictures in other Local map beyond self through local picture that geometric transformation obtains.
Geometric transformation comprises turning-over changed and rotational transform etc.Two identical pictures can be thought and obtain by rotating 360 degrees each other.
Step S40, generates the recovery information of the local picture removed according to the local picture retained.

In one embodiment, step S30 comprises the following steps: remove the local picture of more than two width or two width that can mutually obtain through geometric transformation locally in picture beyond any width.
In one embodiment, the width local picture that step S30 can choose in the local picture splitting and obtain successively compares with remaining local picture, judge that can remaining local picture be obtained through geometric transformation by the local picture chosen, removing in the local picture splitting and obtain can by the local picture chosen through local picture that geometric transformation obtains.
Step S40 can generate the corresponding relation of the geometric transformation that the position of the local picture chosen, the position of the local picture of removal and the local picture that transforms to removal by the local picture chosen need pass through.
Step S50 can store the picture resource of the local picture of reservation and positional information and store the corresponding relation of above-mentioned generation.Namely the picture resource of the local picture of reservation and the positional information of local picture in original image of reservation is stored.
The position of local picture is the position of picture in original image, local.
The position of picture in original image, local can represent with the column locations of the pixel of local picture in original image, concrete, the column locations of two summit pixels in original image that the diagonal line of available local picture connects represents, such as, ((1, 1), (50, 60)) represent that local picture is positioned at the 1st of original image and walks to the 50th row, between 1st row to the 60th row, the pixel of local picture is positioned at the pixel (1 with original image, 1) and (50, 60) connecting line is in cornerwise rectangular coverage area, also can illustrate that the local left upper apex of picture and bottom right vertex are respectively the pixel (1 of original image, 1) and (50, 60).
Such as, note the first local left upper apex of picture and location of pixels of bottom right vertex in original image are respectively (1,1) and (50,60), the second local left upper apex of picture and the location of pixels of bottom right vertex are respectively (1,61) and (50,120).
If one in above-mentioned corresponding relation is recorded as: ((1,1), (50,60)), ((1,61), (50,120)), " flip horizontal+dextrorotation turn 90 degrees ", then above-mentioned record can represent that the second local picture can be turn 90 degrees through flip horizontal and then dextrorotation by the first local picture and obtains.
If be recorded as: ((1,1), (50,60)), ((1,61), (50,120)), "None", or ((1,1), (50,60)), ((1,61), (50,120)), " rotating 360 degrees ", then this record can represent that the second local picture is identical with the first local picture, through geometric transformation or the first local picture rotation 360 degree need not can be obtained the second locally picture.
