图象分类是搜索引擎中的重要模块.本文提出了一种基于特征元素的图象分类方法.特征元素与特征向量相比能够根据人的主观感知来提取图象的视觉特征.与传统的基于特征向量的图象分类方法不同
本文提出的图象分类方法不计算特征空间中特征向量之间的距离
而是通过关联规则挖掘发现图象的特征元素与图象所属类别之间的联系.本文实现了该分类算法并将其与一种基于特征向量的图象分类方法NFL相比较.实验的结果证实了所提方法的优越性.
With the growth of Internet and storage capability in recent years
image has become a widespread information format in World Wide Web.However
it has become increasingly difficult to search for images of interest
So effective image search engine for the WWW needs to be developed.Image classification is an important module in image search engine.In this paper a novel approach for image classification based on feature element is proposed.Compared with feature vectors
feature elements can capture visual meanings of the image according to subjective perception of human beings.By using feature element
our approach for image classification is totally different with traditional image classification method.It does not calculate the distance between two vectors in the feature space
while trying to find associations between feature element and class attribute of the image.After the implementation
we have compared it with NFL ― a traditional image classification algorithm based on feature vector.Some improved results are presented.
