(一)和目标检测2: 目标检测20年综述之(二)让大家对目标检测有个大概的认识,机器学习评价指标合辑(Precision/Recall/F1score/P-R曲线/ROC曲线/AUC)介绍了基础的评价指标,如Precision、Recall、F score等概念,目标检测3: Detection基础之IoU中介绍了目标检测的评价指标IoU,接下来我们介绍目标检测最重要的评价指标mAP...
java基础-数据容器之Map-HashMap 数据容器 在程序代码中,用来暂时存储数据的“盒子”(容器),用于后续的逻辑处理。 为什么需要map? map是数据容器中的一种数据结构,首先它是用来存储数据的;其次,与其它数据容器不同,它是一种可以通过业务数据来快速、精确检索另一个业务数据的数据结构。 map:是一种key-value的...
mAP是mean of Average Precision的缩写,意思是平均精确度(average precision)的平均(mean),是object detection中模型性能的衡量标准。object detection中,因为有物体定位框,分类中的accuracy并不适用,因此才提出了object detection独有的mAP指标,但这也导致mAP没有分类中的accuracy那么直观。但也没有那么复杂,本文将详细解...
def log(self): map_stat = 100. * self.detection_map.get_map() logger.info("mAP({:.2f}, {}) = {:.2f}%".format(self.overlap_thresh, self.map_type, map_stat)) 这不就对应着上面的第二个输出吗 那么我们去而负责阈值部分的就是 self.overlap_thresh 现在我们只需要找到self.overlap_thre...
A method for establishing a detection map of a dynamically configurable sensor network. This method determines an appropriate set of locations for a plurality of sensor units of a sensor network and establishes a detection map for the network of sensors while the network is being set up; the ...
Moreover, given a global map, such as a satellite image, our approach can locate and track the targets in geo-coordinates, namely longitude and latitude. The map information is used as a global constraint for compensating the camera motion, which is critical for motion detection on a moving ...
First, we automatically generate training road annotations for images using OpenStreetMap1, vehicle pose estimation sensors, and camera parameters. Next, we train a Convolutional Neural Network (CNN) for road detection using these annotations. We show that we are able to generate reasonably accurate...
In the big data era, the video data of social media increase rapidly. To detect and block pornographic videos, traditional pornographic image detection met
