Creating an application for AOI

To create our new application, we require a few input parameters when the user executes them; all of them are optional, excluding the input image to be processed:

An input image to be processed
The light image pattern
The light operation, where the user can choose between difference or division operations:
- If the input value of the user is set to 0, then a difference operation is applied
- If the input value of the user is set to 1, then a division operation is applied
Segmentation, where the user can choose between connected components with or without statistics and findContours methods:
- If the input value of the user is set to 1, then the connected components method for the segment is applied
- If the input value of the user is set to 2, then the connected components with the statistics area is applied
- If the input value of the user is set to 3, then the findContours method is applied to the segmentation

To enable this user selection, we will use the command line parser...

Millán Escrivá

Millán Escrivá

David Millán Escrivá was 8 years old when he wrote his first program on an 8086 PC in Basic, which enabled the 2D plotting of basic equations. In 2005, he finished his studies in IT with honors, through the Universitat Politécnica de Valencia, in human-computer interaction supported by computer vision with OpenCV (v0.96). He has worked with Blender, an open source, 3D software project, and on its first commercial movie, Plumiferos, as a computer graphics software developer. David has more than 10 years' experience in IT, with experience in computer vision, computer graphics, pattern recognition, and machine learning, working on different projects, and at different start-ups, and companies. He currently works as a researcher in computer vision.
