Further, the method that the dividing method based on boundary uses Canny edge detection.
Canny edge detection is to extract useful structural information from different visual objects and greatly reduce number to be processed
According to a kind of technology of amount, it is widely used to various computer vision systems at present.To edge detection on different vision systems
Requirement it is more similar, it is thereby achieved that it is a kind of be widely applied meaning edge detecting technology.Edge detection it is general
Standard includes:
1, edge is detected with low error rate, namely is intended to accurately capture as far as possible as much as possible in image
Edge.
2, the edge detected should be accurately located at the center of true edge.
3, the edge given in image should be only labeled primary, and in the conceived case, the noise of image should not produce
Raw false edge.
In order to meet these requirements, in currently used edge detection method, Canny edge detection algorithm is that have sternly
What lattice defined, one of the method well reliably detected can be provided.Since it has three standards and reality that meet edge detection
The existing simple advantage of process, becomes one of most popular algorithm of edge detection.
Canny edge detection algorithm can be divided into following 5 steps:
1, noise is filtered out with smoothed image using Gaussian filter.
2, the gradient intensity of each pixel and direction in image are calculated.
3, inhibit using non-maximum (Non-Maximum Suppression), it is spuious to eliminate edge detection bring
Response.
4, it is detected using dual threshold (Double-Threshold) to determine true and potential edge.
5, by inhibiting isolated weak edge to be finally completed edge detection.
Further, in order to preferably be handled image information, the image partition method based on threshold value is using adaptive
Answer the dividing method of threshold value.
When concrete application, it can be used according to parameters such as gray scale, gradient, forms and set adaptive threshold, this method is claimed
For Da-Jin algorithm (OTSU), it is the gamma characteristic by image, divides the image into 2 part of background and target.Between background and target
Inter-class variance it is bigger, illustrate that the difference for constituting 2 parts of image is bigger, when to be divided into background or part background wrong for partial target mistake
Being divided into target all can cause 2 part difference to become smaller.Therefore, the maximum segmentation of inter-class variance is made to mean misclassification probability minimum.
Further, in order to further increase image quality, described image identification module is also used to fused image
Pseudo Col ored Image is carried out, processing is carried out and is transformed to color image.
Further, the method for Pseudo Col ored Image uses intensity segmentation method, and the intensity segmentation method specifically includes:
Using the grayscale image of fused image as a luminance function, with one be parallel to the plane of image coordinate axis come
Luminance function is cut, luminance function is divided into two gray value intervals, and assign two different colors, is promoted, according to
Different gray levels divides gray value interval, assigns a kind of color to the pixel in each gray value interval.
Further, the method for Pseudo Col ored Image uses frequency domain filtering method, and the frequency domain filtering method specifically includes:
Fourier transformation is carried out to fused image first, according to the different frequency component in region each in image to area
Domain assigns different colors, does not obtain different frequency components and pass through the filters of three different frequency bands respectively generating different frequencies
Rate component, then the frequency component of output is subjected to Fourier inversion, the image of each access is finally separately input to processing
In system in the corresponding entrance of color monitor.
In use, the filter includes red high-pass filter, green bandpass filter and blue low-pass filter.
Further, described image identification module is also used to carry out image enhancement processing, for improving image (pretreatment shadow
As information) in visual effect, improve the clarity of image；Second is that converting images into, one kind being more suitable for the mankind or machine carries out
The form of processing is analyzed, convenient for obtaining more useful information from image.Image enchancing method is roughly divided into two classes: Yi Leishi
Spatial domain facture, another kind of is frequency domain facture；Flexible choice can be carried out when concrete application according to the actual situation, can also be carried out
It is applied in combination, by different types of Image detection, triggering system is automatically switched.
Finally, it should be noted that foregoing description is only a specific embodiment of the invention, but protection scope of the present invention
It is not limited thereto, anyone skilled in the art in the technical scope disclosed by the present invention, can readily occur in
Change or replacement, should be covered by the protection scope of the present invention.
