Problems solved by technology

[0006] However, in the application of fiber optic microendoscopy image analysis based on the morphological characteristics of squamous cells, when enhancing low-contrast fiber optic microendoscopy images, it is necessary to select the best parameter combination through multiple intensity adaptive contrast enhancement experiments. Increased complexity of clinical application

Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0045] In the present invention, the optical fiber microendoscope system uses an optical fiber bundle as a probe for microscopic imaging. Because the light transmittance of a single optical fiber core and the cladding in the optical fiber bundle is different, the image collected will have obvious pixelation (brightness and darkness change) ), reducing the system resolution. The commonly used depixelization method is Gaussian filtering. Although this method is simple, fast and effective, it will blur the entire image and affect the...

Abstract

The invention provides an image contrast enhancement method, system and device, and the image contrast enhancement method comprises the following steps: carrying out the filtering preprocessing of an image collected through an optical fiber microendoscope; carrying out enhancement processing on the filtered image; carrying out nonlinear gray scale transformation on the enhanced image, and calculating a gray scale value of each pixel point on the image after nonlinear gray scale transformation to obtain a new image; and based on the obtained new image, cutting off the value of the lowest pixel of the image, standardizing the highest pixel value, and standardizing the pixel values between 0 and 255 by taking the minimum value and the maximum value of the pixels of the image as standards to obtain an image with enhanced contrast. According to the method, the morphological characteristics of squamous cells in the optical fiber microendoscopic image can be enhanced, the work of endoscopic doctors can be assisted, the work and training burden of doctors can be reduced, and the clinical efficiency can be improved.

Description

technical field [0001] The invention relates to the field of medical image processing and application, in particular to an image contrast enhancement method, system and device based on optical fiber microendoscope images. Background technique [0002] The fiber optic microendoscope based on the fiber optic bundle (hereinafter referred to as the fiber optic microendoscope) has the capability of subcellular real-time imaging. In the application field of esophageal intestinal mucosa screening, many studies have shown that fiber optic endoscopy will generate useful clinical data, which can help early detection of precancerous and cancerous lesions of the esophagus. Therefore, fiber optic endoscopy has great clinical application value in the early detection of esophageal lesions. [0003] Like other advanced esophageal endoscopy techniques, fiber optic endoscopy has a long learning curve, and the diagnostic effect of images depends on the doctor's pathological basis, high-level ...
