Embodiment Construction

[0010] 1. After using a camera or other image acquisition equipment to obtain a laryngeal image, the picture shows not only the throat but also other tissues in the oral cavity. How to deal with laryngeal images to get useful information to help doctors make a diagnosis. In the present invention, the laryngeal image is firstly segmented, and the segmented image approximately includes the tonsil, the palate around the tonsil, and the soft palate part above the tonsil. The laryngeal image segmentation method is a curve evolution method. Draw a curve arbitrarily through the evolution of the curve, specify the movement direction and speed of each point on the curve, let this curve evolve into the curve we want, and realize the segmentation of the throat image.

[0011] After the laryngeal image is segmented, the segmented complete laryngeal image will be analyzed. Beneficial information can be obtained by analyzing some features of the laryngeal image. The features of the laryn...

Abstract

The invention relates to a laryngeal image processing method, which comprises the following steps of: segmenting a laryngeal image by adopting a curve evolution method, wherein the segmented image comprises a tonsil, a palate sag around the tonsil and a soft palate part above the tonsil; Analyzing the segmented complete laryngeal image, extracting laryngeal image characteristics including colors,shapes and laryngeal qualities, carrying out color extraction analysis and comparison on the color characteristics through a fixed RGB space, and regarding the throat image characteristics as inflammation if the color is slightly red and greater than a normal color value. the shape judgment is to judge whether the tonsil and the surrounding palate sag have too large or too small glandular hyperplasia or not and whether the shape meets the standard or not.

Description

technical field [0001] The invention belongs to the field of image analysis and image processing, in particular to a laryngeal image processing method suitable for a laryngeal diagnostic instrument. Background technique [0002] Throat diagnosis plays an extremely important role in the diagnosis of pediatric diseases. However, different doctors may make different judgments on the appearance of the throat of the same child. For example, the identification of the same color by two different physicians may be biased. Therefore, the laryngeal diagnostic instrument is a medical instrument that uses standardized scientific methods to assist doctors in diagnosis, and is of great significance for the diagnosis of pediatric diseases. [0003] Therefore, it is of great significance to study the relevant feature extraction and analysis and processing methods of laryngeal diagnosis images. SUMMARY OF THE INVENTION [0004] The invention provides a laryngeal image processing method f...
