Abstract
The present invention relates to data processing method fields, more particularly to a kind of image data mark index value correction method, by setting default color mapping matrix, by the index value of objects different in other photos and default color mapping matrix to comparing, if any difference, then modify the index value of corresponding objects in other photos, this method compensates for the difficulty that index value mistake can not be found using tools such as stingy figure softwares, keep the index value of the same target in serial-gram identical, it is convenient for machine algorithm learning training, simultaneously the energy of mark person is concentrated on scratching in figure task, improve annotating efficiency.
Description
Technical field
The present invention relates to data processing method field more particularly to a kind of image data mark index value correction methods.
Background technique
In image data annotation process, index value is used to specify the different objects in image in annotation results, for figure
As the availability of annotation results is very crucial.But in continuous picture, the rope for the same target object that stingy figure software plucks out is used
Drawing value can be different, this will lead to machine learning algorithm training mistake.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of by continuous picture
The identical image data mark index value correction method of the index value of same target object.
The present invention is to be achieved by the following technical programs:
A kind of image data mark index value correction method, which comprises the following steps:
A. the first image is read, the first color mapping matrix is obtained, the first color mapping matrix is set as default color
Mapping matrix；
B. the second image is read, second index value matrix is obtained and shows the corresponding index of different colours on the second image
Value；
C. the default color mapping matrix in the index value shown in step b and step a is compared, the rope in step b
Draw value and the default color mapping matrix in step a not to it is corresponding when modified on the second image according to default color mapping matrix
Index value.
The beneficial effects of the present invention are:
This method compensates for the difficulty that index value mistake can not be found using tools such as stingy figure softwares, makes in serial-gram
The index value of same target is identical, is convenient for machine algorithm learning training, while the energy of mark person being concentrated on to scratch figure times
In business, annotating efficiency is improved.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and most
The present invention is described in further detail for good embodiment.
As shown, the present invention the following steps are included:
A. the first image is read, the first color mapping matrix is obtained, the first color mapping matrix is set as default color
Mapping matrix；
B. the second image is read, second index value matrix is obtained and shows the corresponding index of different colours on the second image
Value；
C. the default color mapping matrix in the index value shown in step b and step a is compared, the rope in step b
Draw value and the default color mapping matrix in step a not to it is corresponding when modified on the second image according to default color mapping matrix
Index value.
Embodiment 1
The target index value of first object in the index value and default color mapping matrix of the first object in second image
When can not match, if with second object with target index value with same index value in the second image, by first pair
The index value of elephant is exchanged with the index value of the second object.
Embodiment 2
The target index value of first object in the index value and default color mapping matrix of the first object in second image
When can not match, if not having the second object of same index value in the second image with target index value, manually by the
The index value of an object is revised as target index value.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
Claims (1)
1. a kind of image data mark index value correction method, which comprises the following steps:
