Learning outcomes
|
It is a course focused on image analysis system NIS Elements 2.3 and higher versions, and its using in evaluation of the parameters of textile assemblies. During lectures, students gain theoretical knowledge about the functions of image analysis, which they will practice and deepen during practices.
Students have both theoretical and practical knowledge about the functions of image analysis. They can use it for evaluation the parameters of textile asseblies.
