摘要:

为了在只有几个样本的情况下在待检测图像中采用模板匹配的方式定位目标,提出了一种两阶段投票的目标检测方法。首先采用概率模型通过几个样本离线构造投票空间,然后采用两阶段投票的方式在待测图像中检测目标:第一阶段在待测图像中通过投票检测目标的图像块,并记录下这些部件块在样本中所处的位置信息;第二阶段基于第一阶段所得到的图像块来投票计算样本整体的相似度,从而定位目标。理论推导和实验结果验证了所提出方法比前人的工作具有更低的时间复杂度和更高的目标检测准确率。

Abstract:

A method of object detection with few samples based on two-stage voting was proposed to detect objects using template matching method while there are only a few samples. Firstly, the voting space was constructed off-line by using probability model through several samples. Then, a method of two-stage voting was used to detect objects in testing images. In the first stage, the components of object from testing image were detected, and the positions of components in query image were saved. In the second stage, the similarity of the object was computed integrally based on the components. According to the theory analysis and experimental results, the proposed method obtains lower computation complexity and higher precisions than previous works.
