摘要:
This invention relates generally to the detection of objects, such as stents, within intraluminal images using principal component analysis and/or regional covariance descriptors. In certain aspects, a training set of pre-defined intraluminal images known to contain an object is generated. The principal components of the training set can be calculated in order to form an object space. An unknown input intraluminal image can be obtained and projected onto the object space. From the projection, the object can be detected within the input intraluminal image. In another embodiment, a covariance matrix is formed for each pre-defined intraluminal image known to contain an object. An unknown input intraluminal image is obtained and a covariance matrix is computed for the input intraluminal image. The covariances of the input image and each image of the training set are compared in order to detect the presence of the object within the input intraluminal image.
摘要(中):
本发明一般涉及使用主成分分析和/或区域协方差描述符检测在腔内图像内的物体,例如支架。 在某些方面,生成已知包含对象的预定义的管腔内图像的训练集。 可以计算训练集的主要组成部分以形成对象空间。 可以获得未知的输入管腔内图像并将其投影到对象空间上。 从投影中可以在输入的管腔内图像中检测物体。 在另一个实施例中,为已知包含对象的每个预定义的管腔内图像形成协方差矩阵。 获得未知的输入管腔内图像,并为输入的管腔内图像计算协方差矩阵。 比较输入图像和训练集合的每个图像的协方差,以便检测输入的管腔内图像中物体的存在。
