Embodiment Construction

[0048] Cooperate figure 1 , figure 2 Shown, method of the present invention comprises the following steps:

[0049] ①, image preprocessing

[0050] Any unprocessed original image has a certain degree of noise interference. Noise deteriorates the image quality, makes the image blurred, and even drowns the features, making it difficult to analyze the image. In the medical image matching algorithm based on wavelet and support vector machine, since this method essentially depends on the correlation of the image gray level in the spatial distribution, this method is very effective for the description of the difference between images, but it The difference caused by noise cannot be distinguished, which is the theoretical defect of this matching method. Therefore, preprocessing must be carried out in the early stage of the method to remove the image difference between the input images, try to highlight the essential difference between the images, and match the template image with...

Abstract

The disclosed medical image template matching method based on microcomputer comprises: pre-processing image, training sample with SVM instead of RNN, extracting feature by complex wavelet, and finding out the optimal matching. This invention overcomes defects in prior art, improves speed and robustness, and has strong adaptability.

Description

technical field [0001] The invention relates to a medical image template matching method, in particular to a microcomputer-based medical image template matching method. Background technique [0002] In the past ten years, various new medical imaging devices have developed rapidly and are widely used in clinical diagnosis and treatment. Defects, so that the clinical diagnosis and treatment more comprehensive and accurate. Multimodal medical image registration is to register images from different medical imaging devices. Since different modes of equipment have different sensitivities and resolutions for tissues in the human body, as small as molecules and atoms, they have their own scope of application and limitations. The combination of multiple modes of images can make full use of the characteristics of the image itself and achieve information complementarity. Current medical imaging modes can be divided into two categories: functional imaging (SPECT, PET, etc.) and anato...
