Example Embodiment

[0027] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0028] Such as figure 1 As shown, a flow chart of an image highlight elimination method affected by the surface highlight reflection includes:

[0029] S1, based on the SVM model, separate the highlight pixels of the image;

[0030] S2, using the adjacent areas of the image with structural similarity to assign and repair the highlight pixel area.

[0031] The highlight separation method of this embodiment is based on the assumption that there is a hyperplane in a high-dimensional space, which can effectively separate highlight and non-highlight pixels in the image.

[0032] Before S1, combine the existing automatic segmentation method and manual correction method to obtain the precise separation result of the image hi...

Abstract

The invention provides a method and a system for eliminating highlight of an image affected by highlight reflection on an object surface. The method comprises the following steps of S1.separating a highlight pixel of the image based on an SVM model; and S2.utilizing adjacent regions with structural similarity of the image to carry out assignment restoration on a highlight pixel region. A statistical learning method is utilized and the highlight pixel of an endoscope image is automatically separated based on an SVM classifier, the method fully utilizes the advantages of sample learning, after a separation model is obtained through training, an optimal classification result can be obtained without artificial participation; an image restoration method based on dynamic search and similarity measure is provided in the aspect of image restoration in order to fully utilize the effective information of the adjacent regions with the structural similarity in the full range, and the natural restoration of the highlight region is realized.

Description

technical field [0001] The present invention relates to the field of image processing, and more specifically, to a method and system for removing high light from an image affected by high light reflection on the surface of an object. Background technique [0002] At present, compared with traditional surgery, minimally invasive surgery only causes very small trauma to human tissue, and this technology can significantly reduce postoperative recovery time and mortality. Therefore, research on minimally invasive surgery and related auxiliary diagnosis and treatment methods has become a hot spot in medical technology research today. [0003] Endoscopic images provide clinicians with a true view of the internal environment as well as organ surfaces. An endoscope usually refers to a fixed tubular camera with a fiber optic light source fixed at the top of the camera for illumination and imaging. During the operation, the surgeon can obtain a real-time image of the surgical scene ...
