中文简介:
我们描述了一种通用而精确的方法来大大加快线性物体检测系统以滑动、多尺度窗口方式运行,例如基于零件模型的单个零件检测器。其中许多系统的主要瓶颈是要处理的图像的多重重定距与线性滤波器之间的卷积计算成本。我们利用傅立叶变换的特性和巧妙的实现策略来获得与滤波器大小成比例的加速因子。性能的提高在著名的PascalVOC基准上得到了证明,在该基准上,我们将上述卷积的速度提高了一个数量级。
课程简介: We describe a general and exact method to considerably speed up linear object detection systems operating in a sliding, multi-scale window fashion, such as the individual part detectors of part-based models. The main bottleneck of many of those systems is the computational cost of the convolutions between the multiple rescalings of the image to process, and the linear filters. We make use of properties of the Fourier transform and of clever implementation strategies to obtain a speedup factor proportional to the filters' sizes. The gain in performance is demonstrated on the well known Pascal VOC benchmark, where we accelerate the speed of said convolutions by an order of magnitude.
关 键 词: 线性滤波器; 傅立叶变换; 加速因子
