Image processing method and system in electronic colposcope

Abstract

The invention provides an image processing method in a electronic colposcope. Firstly, an image to be processed is segmented into three parts by using an image segmentation method, and for a key observation area, an interpolation method with high precision is adopted, and for a non-key observation area, a bilinear interpolation method with high calculation speed is adopted for interpolation; the first part is interpolated by adopting a first interpolation method, the second part is interpolated by adopting a second interpolation method, and the third part is interpolated by adopting a bilinear interpolation method. The inserted pixels of the first boundary region and the second boundary region in the intermediate image obtained after interpolation are corrected because the interpolation is easy to cause a sawtooth phenomenon in the boundary region. According to the method provided by the invention, the image processing speed of the electronic colposcope is improved, and high-quality images can be obtained.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to image processing in electronic colposcopes. Background technique [0002] Electronic colposcopy (Colposcopy) is an important device for checking women's vagina and cervix. Doctors can check whether there are abnormalities in the vagina and cervix through electronic colposcopy. The basic principle of electronic colposcopy is to put a Charge Coupled Device (CCD) and LED cold light source deep into the patient's vagina, transmit the image data collected by the CCD to the computer, and then display the image inside the vagina on the monitor through computer processing. The electronic colposcope can magnify the image dozens of times, and can display tiny lesions, erosions, etc. on the monitor through the electronic colposcope. Because it is a non-invasive inspection method, the electronic colposcope has been widely used in the examination of gynecological diseases. ...

AI Technical Summary

Problems solved by technology

If a complex image processing method is used, although the image quality has been improved, the processing speed of the processor cannot match the CCD, which may cause a freeze; and if a simple image processing method is used, the processing speed is improved. However, the image quality will be reduced. For example, if a doctor enlarges the image, there will be obvious jagged edges

[0004] Image quality and processing speed are contradictory, and it is impossible to satisfy both at the same time. Now most of them focus on the improvement of image processing methods, but so far there is no simple, fast and high-quality image quality method.
