Title
(EN) Content based image retrieval
(ZH) 基于内容的图像检索
Abstract
(EN)
A method and non-transitory computer readable medium for content based image retrieval. The method includes selecting a query image, segmenting the selected query image by applying a segmentation technique, extracting features from the segmented query image by determining at least two feature descriptors, including color feature descriptors and texture feature descriptors, and determining a similarity of the query image to a plurality of images included in a database using the determined at least two feature descriptors of the segmented query image, features being extracted from each of the plurality of images included in the database by determining the at least two feature descriptors, the color feature descriptors and the texture feature descriptors including a simultaneous combination of different color spaces, and global and local statistical measurements being carried out on the simultaneous combination of the different color spaces.

一种用于基于内容的图像检索的方法和非暂态计算机可读介质。该方法包括选择查询图像;通过应用分割技术将所选择的查询图像进行分割;通过确定至少两个特征描述符来从所分割的查询图像提取特征,至少两个特征描述符包括颜色特征描述符和纹理特征描述符;以及使用所分割的查询图像的所确定的至少两个特征描述符来确定查询图像与被包括在数据库中的多个图像的相似性,通过确定至少两个特征描述符从被包括在数据库中的多个图像中的每个图像来提取特征,颜色特征描述符和纹理特征描述符包括不同的颜色空间的同时组合,并且对不同的颜色空间的同时组合执行全局和局部统计测量。
