    • A system and method for content-based search and retrieval of visual objects. A base visual information retrieval (VIR) engine utilizes a set of universal primitives to operate on the visual objects. An extensible VIR engine allows custom, modular primitives to be defined and registered. A custom primitive addresses domain specific problems and can utilize any image understanding technique. Object attributes can be extracted over the entire image or over only a portion of the object. A schema is defined as a specific collection of primitives. A specific schema implies a specific set of visual features to be processed and a corresponding feature vector to be used for content-based similarity scoring. A primitive registration interface registers custom primitives and facilitates storing of an analysis function and a comparison function to a schema table. A heterogeneous comparison allows objects analyzed by different schemas to be compared if at least one primitive is in common between the schemas. A threshold-based comparison is utilized to improve performance of the VIR engine. A distance between two feature vectors is computed in any of the comparison processes so as to generate a similarity score.
    • 一种用于基于内容的视觉对象搜索和检索的系统和方法。 基础视觉信息检索(VIR)引擎利用一组通用原语来对视觉对象进行操作。 可扩展的VIR引擎允许定义和注册定制的模块化图元。 自定义原语解决领域特定问题,并可以利用任何图像理解技术。 对象属性可以在整个图像上或仅在对象的一部分上提取。 模式被定义为特定的基元集合。 具体的模式意味着要处理的一组特定的视觉特征以及用于基于内容的相似性评分的相应特征向量。 原始注册界面注册自定义原语,并便于将分析功能和比较功能存储到模式表。 如果至少一个原语在模式之间是共同的,则异构比较允许比较不同模式分析的对象。 利用基于阈值的比较来提高VIR引擎的性能。 在任何比较过程中计算两个特征向量之间的距离,以便生成相似性得分。
