Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The example of the present invention provides a kind of image color space conversion, the method for feature recognition and feature extraction, such as figure 1 shown, including the following steps:

[0029] Step 1: Define a new color space, map the original tongue map to the new color space according to the transformation matrix, and obtain the tongue map after the enlarged prick feature, as shown in image 3 . figure 2 It is a three-dimensional information map of tongue map color in RGB space.

[0030] Step 2: Combined with the maximum inter-class variance algorithm, define the size of the filter operator according to the size of the tongue map, and dynamically define the weighting coefficient of the operator according to the color information of the tongue map points;

[0031] Step 3: Use the operator generated in step 2 to perf...

Abstract

The present invention relates to the computer technology field, in particular to an image feature identifying and extracting method. The method comprises the steps of establishing a color space, mapping a tongue picture to the new color space according to a mapping relationship of the RGB and the new color space, referencing a maximum between-cluster variance algorithm, dynamically defining a filtering operator, carrying out the high-pass filtering on the tongue picture, filtering the tongue body information, obtaining a tongue body approximate pricking information distribution diagram, carrying out the denoising smoothing operation according to a newly obtained image matrix, and obtaining and extracting the accurate tongue body pricking information.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for identifying and extracting image features. Background technique [0002] Diagnostics of traditional Chinese medicine is a discipline spanning basic and clinical. It makes the symptoms and signs correspond to syndrome-type diseases one by one, and is the primary way for doctors to diagnose and treat diseases. Observation diagnosis is the first of the four diagnostic methods of traditional Chinese medicine, "observation, hearing, questioning and palpation". [0003] Tongue diagnosis is often mentioned in inspection and can be said to be the most characteristic diagnostic method of traditional Chinese medicine. Tongue diagnosis fully embodies the principle of disease recognition in TCM diagnostics. TCM believes that the human body is an indivisible organic whole, and every part of the body is closely related to the whole or other parts. Outline Syndrome Differentiat...
