Our client is a Californian artist, a teacher, and a founder of educational resource Proko. He turned to Azoft to develop a custom tool that analyzes and corrects lines in students’ drawings automatically. We used machine learning and neural networks to create solutions that help:rate drawings on a scale of 1 to 5check if the perspective is correct suggest corrections to parallelepiped drawingsFor the algorithm that automatically corrects errors in parallelepiped drawings, we created a web application that helps students get their works checked in a couple of clicks. The developed algorithms save teacher’s time by searching for and correcting the standard errors of novice artists. The tool will be integrated into an e-learning platform.
