Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As described in the background art, existing image segmentation and the method for storage, consume a large amount of memory spaces, and each
Secondary inquiry and retrieval data will be by databases；In the case where request amount is big, because checking storehouse in real time, to database
Pressure is larger, and influences server performance.Efficiency is relatively low in the case of maintenance and inquiry.
In order to solve the problem, the method that the embodiment of the present application provides a kind of storage of digital specimen tile data can be with
The method for solving conventional images segmentation and storage, consumes the problem of a large amount of memory spaces.
A kind of flow of the method for the digital specimen tile data storage for being provided for the embodiment of the present application as shown in Figure 1
Figure, the described method comprises the following steps：
(1) by the treatment of original image data slicer, the picture of each multiplication factor is obtained, and divided according to multiplication factor
Level, the picture of each level is placed in a file.
One large scale original image is divided into the tile data comprising some sub-pictures, the picture in this article all referring to
Sub-pictures after cutting, specific cutting method includes splitting former large-size images according to N*N (N ＞ 1) Pixel Dimensions, solves
The storage problem of large scale picture, and multiplication factor is positive integer.
(2) file in step (1) is named as x, x is consistent with level is amplified, all pictures comprising this multiple, text
Part folder is arranged from small to large by numerical order.
As shown in Figure 2, file name x is the multiplication factor of picture in Arabic numerals, and the size and this document of x
Identical, file is arranged from small to large by numerical order, meets use habit of the people to numeral, facilitates the reading of picture.
(3) picture in each file in step (2) is named with (y, z) .jpg forms to the picture, wherein y, z
It is Picture Coordinate, the picture is arranged in order.
Herein described y, z for Picture Coordinate be position coordinates of the picture in original image, y is picture in original graph
Line number where in piece, z is row number of the picture where in original image, wherein, y, z value are natural number；Picture is in order
Arrangement refers to that picture is arranged according to first y positive sequences, then the order of z positive sequences, for example：0-0,0-1,1-0,1-1 etc..
(4) picture in file in step (3) is stored in big file with byte [] type, and records each picture
Position and occupancy byte number in big file.
Big file herein refers to the file where original image, and this storage method does not change the road of picture storage
Footpath, simplified step is easy-to-look-up, records position of the picture in big file, and information is provided to read, and records picture big
Byte number is taken in file, it is ensured that information is as detailed as possible.
(5) information of the picture in file in step (3) is appended to greatly according to the order of storage picture in step (4)
In file.
It is described herein pictorial information is appended in big file with storing the order of picture, facilitate the reading of pictorial information.
(6) the original image said module information in step (1) is written in step (5) big tail of file.
Time when picture reads is reduced, is easy to the reading of image data.
Picture in the step of method of digital specimen tile data storage (4) there may be various forms, more general
Time form be JFIF forms, if JFIF forms, only preserve wide high and from the data between ff da to ff d9, true
In the case that guarantor's data are complete, the space shared by data storage is reduced as far as possible；If extended formatting, or do not meet according to reality
Border needs the related preset requirement of setting, then keep whole picture.
The information of each picture of storage is needed in the step of method of digital specimen tile data storage (5) can wrap
Include：Positional information, hierarchical information, slice information；Positional information refers to Pictures location coordinate y, z, have recorded each level to figure
The transverse and longitudinal quantity of piece segmentation, hierarchical information refers to the value of x, have recorded the picture and has how many level and each level to figure
The transverse and longitudinal quantity of piece segmentation, as shown in Figure 3, each hierarchical information can take 12 bytes.The information of wherein picture may be used also
With including the byte number shared by hierarchical information, picture number and slice information；Positional information includes 69 words as shown in Figure 4
Section, substantially reduces the space shared by whole original image on the basis of existing technology；Storage level is believed as shown in Figure 5
Byte number length shared by breath, picture number and slice information can be fixed as 26.
Further, the slice information in step (5), switchs to byte storage of array and reduces storage area with Json character strings.
As shown in Figure 6, module information content-length can in the step of method of digital specimen tile data storage (6)
To be fixed as 20.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or uses the present invention.
Various modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The scope most wide for causing.
