Abstract
The present invention discloses a method for digital processing of a medical image, and the method includes: dividing the medical image into image frames of different resolution ratios using a pyramid algorithm; performing image enhancement process on a related area of the image frames; performing signal equalization and noise suppression on the image frames; equally sampling the image frames according to a set space interval to obtain an analog signal of the image frames; performing quantization on the analog signal to obtain a quantized discrete signal; encoding the discrete signal to obtain an encoded signal; and compressing the encoded signal using a wavelet transform image compression encoding method. The method for digital processing of the medical image provided by the present invention can transform normal medical images into digital discrete signals for being processed by computer programs.
Description
Technical field
The present invention relates to medical image processing field, be specifically related to a kind of digitalized processing method of medical image.
Background technology
Medical image is the important means of medical diagnosis, Digital Medical Image has larger superiority than analog signal medical image, become by analog signal medical image being carried out to digitized processing the digital signal of calculating function identification, process and can greatly save doctor's processing time by computer program, also make up young doctor and checked that medical image lacks experience, easily caused the shortcoming of mistaken diagnosis.
Summary of the invention
The object of this invention is to provide the digitalized processing method of medical image, general medical science image can be become to digitized discrete signal, process for computer program.
One embodiment of the present of invention provide the digitalized processing method of medical image, comprising: adopt pyramid algorith to resolve into the picture frame of different resolution medical image; Image enhancement processing is carried out in the relevant range of picture frame; Picture frame is carried out to signal equalization and noise suppressed; According to the space interval of setting, picture frame is carried out to uniform sampling, obtain the analog signal of picture frame; Analog signal is carried out to quantification treatment, obtain the discrete signal quantizing; Discrete signal is encoded, obtain code signal; And code signal is compressed to processing with wavelet image compaction coding method.
The digitalized processing method of medical image provided by the invention, can become general medical science image digitized discrete signal, processes for computer program.
Brief description of the drawings
Figure 1 shows that the flow chart of an embodiment of the digitalized processing method of medical image of the present invention.
Figure 2 shows that picture frame of the present invention carries out the flow chart of an embodiment of uniform sampling.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and corresponding accompanying drawing, technical solution of the present invention is clearly and completely described.
With reference to figure 1, Figure 1 shows that the flow chart of an embodiment 100 of the method for the visible light communication signal of identification video camera reception of the present invention.Embodiment 100 comprises the steps 101 to 107.
In step 101, adopt pyramid algorith to resolve into the picture frame of different resolution medical image.
In step 102, can carry out image enhancement processing to the relevant range of picture frame, by some information that specifically need to give prominence in piece image, meanwhile, slacken or remove some unwanted information.
In step 103, picture frame is carried out to signal equalization and noise suppressed, can the less signal of gain amplifier, suppress the signal that gain is larger, noise suppressed can make signal more clear.
The step of in one embodiment of the invention, picture frame being carried out to signal equalization and noise suppressed comprises: picture frame is carried out to high-pass filtering.
In step 104, according to the space interval of setting, picture frame is carried out to uniform sampling, obtain the analog signal of described picture frame.
In one embodiment of the invention, step 104 further comprises step 201 ~ 204.
Figure 2 shows that picture frame of the present invention carries out the flow chart of an embodiment of uniform sampling.
In step 201, use the first sample frequency to sample to picture frame.
In step 202, picture frame is divided into multiple parts, and for each in multiple parts draws pixel and value, to form first group of pixel and value.
In step 203, use the second sample frequency to repeat above-mentioned steps, to form second group and value.
In step 204, the difference based between two groups and value is determined the sample frequency needing, and sample frequency is confirmed as the maximum of difference and the function of minimizing quantity between two groups and value.
In step 105, analog signal is carried out to quantification treatment, obtain the discrete signal quantizing.
In step 106, discrete signal is encoded, obtain code signal.
In step 107, code signal is compressed to processing with wavelet image compaction coding method, can save memory space, be convenient to signal fast transport.
Although the present invention has been made to detailed description with above-mentioned preferred embodiment, has not limited the present invention with above-described embodiment.Those skilled in the art should recognize in the case of not departing from technical solution of the present invention given technical characterictic and scope, and increase that technical characterictic is done, with the replacement of some same contents of this area all should belong to protection scope of the present invention.
