Abstract
A kind of unilateral intermediate value partitioning algorithm, it is assumed that graticule is composed of several sides, a spike such as occurs, it is believed that it is composed of two sides, and then, the segmentation of graticule just switchs to the segmentation on side, i.e., side is set to a part to divide.
Description
Technical field
The present invention relates to field of image processings.
Background technique
For Local threshold segmentation method, how to determine that regional area is the key that one of them is important.Traditional local threshold
Value split plot design only considers some parameters such as variance, mean value in region etc., and the considerations of lacked to provincial characteristics.For biography
Unite local threshold graticule segmentation in there are the problem of, present invention uses unilateral median method threshold value and segmented images, though
So it is not so good as traditional Local threshold segmentation method in applicability, but divides this in graticule and specifically apply inner, unilateral intermediate value
The performance of method is much better than traditional Local threshold segmentation method.
Summary of the invention
For presently, there are main problem, the present invention provides a kind of Local threshold segmentation method.
The present invention provides a kind of unilateral intermediate value partitioning algorithm, it is assumed that graticule is composed of several sides, such as occurs one
A spike, it is believed that it is composed of two sides, and then, the segmentation of graticule just switchs to the segmentation on side, i.e., is set to side
One part is divided.
Further, each edge uses the maximum value on side and the average value of minimum value to divide as threshold value.
Although the beneficial effects of the present invention are: being not so good as traditional Local threshold segmentation method in applicability, in graticule
Divide this and specifically apply inner, the performance of unilateral median method is much better than traditional Local threshold segmentation method.
Specific embodiment
In order to which filtering image noise carries out mean filter for collected graticule data.In order to preferably remove part
Interference, can be used the processing method of direct current.DC processing is exactly that the data after wicket mean filter are subtracted big window
Data after mouth mean filter.
For Local threshold segmentation method, how to determine that regional area is the key that one of them is important.Traditional local threshold
Value split plot design only considers some parameters such as variance, mean value in region etc., and the considerations of lacked to provincial characteristics.For biography
Unite local threshold graticule segmentation in there are the problem of, present invention uses unilateral median method threshold value and segmented images, though
So it is not so good as traditional Local threshold segmentation method in applicability, but divides this in graticule and specifically apply inner, unilateral intermediate value
The performance of method is much better than traditional Local threshold segmentation method.
: it is assumed that graticule is composed of several sides, such as there is a spike in unilateral intermediate value partitioning algorithm principle, can be with
Think that it is composed of two sides, then, the segmentation of graticule just switchs to the segmentation on side, i.e., side is set to a part to divide
It cuts.Each edge uses the maximum value on side and the average value of minimum value to divide as threshold value.
Analyze the gray value curve through DC processing.Stain in each edge represents the threshold value on the side, the threshold of each edge
Value is equal to the maximum value on the side and the mean value of minimum value.The segmentation of each edge be it is independent, i.e., the threshold value of a line only to oneself
Segmentation, without will affect other sides.
