The company name "Open Sesame" is known to everyone, "Open Sesame!".
There is a thought that "we will open your future with advanced technology".
In order to achieve that, it is necessary to always raise the spirit and actively adopt the latest technology.
For this reason, we are constantly working with our employees to create an environment where all employees can improve their skills.
People of different age, gender, educational background, nationality, and technicians gather together here.
It is this group of technicians who boldly challenge new technologies and make impossible possible.

Technical Strength


In recent years, AI has been applied in a wide range of fields.
It is actively used especially in the field of image processing.We have developed systems that recognize faces, people, objects, and quantities from photographs and camera images. Also developed systems that detects exterior and interior walls on drawings to support conduit design.
Currently, we are working on the theme of recognizing objects that are moving and developing functions to track people and objects and recognize their movements. Based on this, we are also working on prototype applications that can be operated by gestures.
In the future, we aim to challenge the fields of speech recognition and text processing.
