 +===== Introduction =====
 +
 +**Images finding images**: ​ LTU engine is the foundation for visual search: ​ image matching, similarity search, and color search.
 +
 +
 +
 +Visual search is using one image to find other images. ​ Visual search based upon the content of an image, rather than based on textual information. ​
 +
 +
 +
 +Two key technologies of visual search are image description and image search.
 +
 +
 +**Image description (Indexation)**: ​ The first step toward making an image searchable is to create a descriptor of the image content. ​ LTU engine computes a visual signature for every image that describe its visual content in terms of color, shape, texture and many higher order visual features. These descriptors are also called image DNAs.
 +
 +
 +
 +**Image search**: ​ Image search is the comparison of one image signature with another, or with millions of other signatures. ​ LTU's proprietary architecture includes a special comparison technology by which an image signature can be compared at extremely high speed with other image signatures.  ​
 +
 +The core data for LTU engine is the **signature**,​ also called the image **DNA**, not the image itself. Image signatures are presented in the "​**Create Application**"​ section of the "​Administrative Interface"​ guide below. ​

 +These principal functionalities are packaged in **LTU engine**, which provides the components necessary for creating and managing visual search applications,​ including JSON API and a comprehensive Administrative Interface. ​   ​
