摘要:

针对关节式物体检测的复杂性,本文提出一种新颖的视觉推理方法。该方法基于可变形的物体模型,同时利用图像中所包含的边缘信息特征(不依赖于局部特征,如肤色等)及各子部件的空间位置关系,迭代地进行关节式物体检测和定位估计。实验证明,该方法有较强的抗背景干扰能力,视觉上能大幅度改进关节式物体检测、定位的结果。

Abstract:

Aiming at the complexity of articulated object detection, this paper proposes a novel casting of visual inference, based on a standard object model, makes full use of the edge feature of the image(it does not rely on local features), as well as the space information of objects, and performs an iterative parsing process, where we can sequentially handle the articulated object detection and estimate the local object components. Experiments show that this method has a strong resistance to the background interference, and can also greatly improve the results of articulated object detection by human vision.
