Embodiment Construction

[0047] The technical idea of ​​the present invention is: select a region of interest (ROI) according to the characteristics of the medical ultrasound image to be processed, extract image feature information and perform de-redundancy processing, and use SVM to classify the features of the region of interest. See the specific process figure 1 , including the following 5 steps:

[0048] Step 1. Select the medical ultrasound image to be processed, and obtain the region of interest ROI as the recognition region;

[0049] Step 2. Preprocessing the ROI, such as denoising, enhancing, etc.;

[0050] Step 3, performing feature extraction on the selected ROI;

[0051] The image features that can be extracted by the present invention include three types, namely texture features, morphological features and elastic features. In the present invention, the more complete the extracted features are, the better it can reflect the essential characteristics of the image.

[0052]Among them, th...

Abstract

The invention discloses an automatic medical ultrasonic image recognition method based on redundant characteristic reduction. The method comprises the following steps of: extracting regions of interest from a medical ultrasonic image to be processed, and extracting characteristics from the regions of interest; analyzing principal components of the extracted characteristics, removing redundancy and irrelevant characteristic components, and determining independent and effect characteristics; and finally classifying the regions of interest by a classifier according to the independent and effect characteristics. The medical ultrasonic image is analyzed through a computer, the space and frequency domains are covered by the extracted image characteristics, the essential characteristics of the image are more comprehensively reflected, and the accurate classification is promoted, so that the method has high clinical practicality.

Description

technical field [0001] The present invention relates to the field of computerized medical image analysis, in particular to a method for automatic recognition of medical ultrasound images based on redundant feature reduction, through feature extraction and de-redundancy of pre-analyzed medical ultrasound image regions of interest (ROI), using a classifier Its features are classified after training and learning, which provides an important reference for clinical application. Background technique [0002] In the past 20 years, medical imaging technology has achieved rapid development. Ultrasound imaging, as an important branch, has been widely used in clinical diagnosis due to its advantages of low cost, real-time, non-invasive, non-ray radiation, high repeatability and sensitivity. , and become an important tool. Ultrasound imaging holds great promise for quantitative analysis, real-time diagnosis, and surgical planning. However, image defects such as speckle noise and artif...
