基于颜色和纹理特征图像检索技术的研究

对基于内容的图像检索中的低层特征的相关检索算法进行了深入研究,对现有颜色和纹理的自然特征中提取出的特征量的检索成功率进行了测试,发现使用单一的特征对图像进行检索查全率不高.为了提高查全率,综合了颜色和纹理特征的检索算法,给颜色特征和纹理特征分配一定的权重,设计了权重设计器,确定了查全率达到最高值时颜色和纹理特征的权重分配,提高了检索效率,识别效果很好.

Research of Color and Texture-based Image Retrieval Technique

The deep research based on the relevant characteristics of low-level search algorithm of the image retrieval is mainly conducted. With the purpose of an in-depth study of color and texture of the existing natural features a characteristic of the success rate of retrieval is extracted.It is discovered that the use sole characteristic carried on the retrieval recall to the image not to be high,to raise the recall. The color and the textural property searching algorithm,giving the color characteristic and text...
