摘要:

本研究提出了一种新的无监督医学图像特征提取方法,该方法采用空间分层技术。提出了一种基于权重的目标函数,以实现快速图像识别的目的。该算法将图像的像素划分为多个子域,并使用四叉树访问图像。提出了一种利用单纯形算法进行阈值优化的技术。针对高光谱图像的非线性特征,提出了一种基于核函数的广义判别分析算法。本项目以高光谱遥感图像为对象,研究其数学建模、求解方法和特征提取技术。研究发现,不同类型的对象在图像处理中相互独立且紧凑。与传统的线性判别方法相比,图像分割效果更好。该方法不仅能克服传统方法易受光照影响的缺点,而且能快速、准确地提取目标特征。对临床诊断具有重要的参考意义。

英文摘要:

This study introduces a novel unsupervised medical image feature extraction method that employs spatial stratification techniques. An objective function based on weight is proposed to achieve the purpose of fast image recognition. The algorithm divides the pixels of the image into multiple subdomains and uses a quadtree to access the image. A technique for threshold optimization utilizing a simplex algorithm is presented. Aiming at the nonlinear characteristics of hyperspectral images, a generalized discriminant analysis algorithm based on kernel function is proposed. In this project, a hyperspectral remote sensing image is taken as the object, and we investigate its mathematical modeling, solution methods, and feature extraction techniques. It is found that different types of objects are independent of each other and compact in image processing. Compared with the traditional linear discrimination method, the result of image segmentation is better. This method can not only overcome the disadvantage of the traditional method which is easy to be affected by light, but also extract the features of the object quickly and accurately. It has important reference significance for clinical diagnosis.
