-LTU ENGINE/ON DEMAND  +
- +
-LTU engine/ON demand is a hosted software platform that provides quick and seamless access to LTU  +
-technologies’ comprehensive image recognition functionalities.  +
- +
-With limited upfront investment and no internal infrastructure or hardware needed, implementing LTU  +
-engine/ON demand is both affordable and risk-free. The LTU engine/ON demand platform is highly  +
-flexible and is designed to adjust and scale with changing demands +
- +
-A single account for LTU engine/ON demand can be used to add image recognition functionality to  +
-multiple applications. Designed as a toolbox including image matching and similarity search, you can  +
-select the features needed today and freely add and remove functionality without having to acquire new  +
-software licenses or adjust IT infrastructure in the future.  +

-MATCHING Detection of the same image or images that have been edited in any way.  +
-What it does  +
-Match images that have been distorted, printed and scanned, edited,  +
-cropped, used in compilations  +
-Find duplicates within an image collection  +
-Complements search using images uploaded by end-users ​+

-SIMILARITY Find images with similar global characteristics based on a combination of  +
-shapes and colors +
-What it does:  +
-Enables combined text keyword and image search  +
-Enables fast and easy browsing by bouncing on similar images – “see  +

 +    *Estimate number of searches per month  
 +  ***Development**  
 +    *List the public IP addresses of all machines that will make direct calls to the API interface.  
 +    *Launch sample code provided by LTU Tech to check that everything works  
 +    *Start development and unit test  
 +    *Validate (pay attention at the refresh delay per application)  
 +    *Empty ​the database and start loading content for the application ​ 
 +  ​***Production**  
 +    *Monitor the number of queries per month (also available on the LTU engine/ON demand administrative console)  
 +    *Continuously evaluate the capacity used monthly in terms of queries and image database volume ​
  
-Synchronous mode  
  
-In synchronous mode, when you query the Modify API the system will instantly process the query, update ​ 
-the database and your application. ​ 
- 
-Administration Console ​ 
- 
-LTU engine/ON demand can be accessed through an administration console that provides easy access ​ 
-to account information,​ application overview and status and history reports. ​ 
- 
-Below are some tasks that can be performed through ​ 
-the administration console: ​ 
- 
-Allow, revoke and monitor remote access via  
- 
-an IP white-list ​ 
- 
-View live applications status ​ 
- 
-Review and report on activity history ​ 
- 
-Request and report support issues ​
