Class imbalance is a common problem in machine learning, where the total number of one class of data is far less than that of another class of data. Class imbalance affects the quality and reliability of results in machine learning tasks as most of the evaluation metrics assume a balanced class d...

Plane detection is a widely used technique that can be applied in many applications, e.g., augmented reality (AR), where we have to detect a plane to generate AR models, and 3D scene reconstruction, especially for man-made scenes, which consist of many planar objects.
