Moving object detection from moving platforms using Lagrange multiplier

Moving object detection is the first key step for many automated vision analysis applications. One of the major challenges to achieve accurate moving object detection is detecting moving objects in videos captured by moving camera platforms, also called active cameras, where both interest objects and background elements are moving. This paper presents a novel algorithm for moving objects detection from active cameras. The proposed method decomposes a video from an active camera into three components: background, moving objects, and transformation matrix between consecutive frames. The proposed method formulates the problem as a robust principle component analysis (PCA) problem (low rank matrix optimization problem) and solves it using inexact augmented Lagrange multiplier (IALM). In the proposed method, the background represents the low rank matrix, and the moving objects and transformation matrix are treated as added corruption. The robustness of the proposed method is demonstrated using a challenging dataset captured by camera mounted on unmanned air vehicle. The obtained results show that the proposed method achieves best results compared to other current state-of-the-art relevant methods.
