From: 手机端运行卷积神经网络的一次实践 -- 基于 TensorFlow 和 OpenCV 实现文档检测功能 貌似不错的东西:移动端视觉识别模型:MobileNets Holistically-nested Edge Detection 是屠卓文教授课题组在ICCV 2015 的工作. 该工作最大的亮点在于,一改之前边缘检测方法基于局部策略的方式,而是采用全局的图像到图像的处理方式. 即:不再针对一个个patch进行操作,而是对整幅图像进行操作,为高层级信息的获取提供了便利. 题材看上去很…

在OpenCV中已经封装的很好只需要使用cv::CascadeClassifier类就可以很容易的实现面部的检测, 三大步: 1.训练好的特征分类器配置文件haarcascade_frontalface_alt.xml 2.使用CascadeClassifier类方法加载配置文件,face_cascade.load("haarcascade_frontalface_alt.xml") 3.使用CascadeClassifier类方法检测一张图片face_cascade.detectMu…

前不久CVPR的结果出来了,首先恭喜我一个已经毕业工作的师弟中了一篇文章.完整的文章列表已经在CVPR的主页上公布了(链接),今天把其中一些感兴趣的整理一下,虽然论文下载的链接大部分还都没出来,不过可以follow最新动态.等下载链接出来的时候一一补上. 由于没有下载链接,所以只能通过题目和作者估计一下论文的内容.难免有偏差,等看了论文以后再修正. 显著性 Saliency Aggregation: A Data-driven Approach Long Mai, Yuzhen Niu, Fen…

在Opencv初接触,图片的基本操作这篇手记中,我介绍了一些图片的基本操作,视频可以看作是一帧一帧的图片,因此图片操作其实是视频操作的基础,这篇手记就来讲讲OpenCV中的视频操作,并实现一个用笔记本自带的摄像头探测人脸的小功能,最后会把人脸提取出来并保存,作为后续用卷积神经网络进行人脸识别的训练数据. 本地视频读取 OpenCV中是通过创建一个VideoCapture对象来捕获视频,这里先以读取和播放本地视频为例: import cv2 cap = cv2.VideoCapture('clem…

http://www.chinacloud.cn/show.aspx?id=25992&cid=12 本文中,笔者将介绍OpenFace中实现人脸识别的pipeline,这个pipeline可以看做是使用深度卷积网络处理人脸问题的一个基本框架,很有学习价值,它的结构如下图所示: Input Image -> Detect 输入:原始的可能含有人脸的图像. 输出:人脸位置的bounding box. 这一步一般我们称之为“人脸检测”(Face Detection),在OpenFace中,使用的…
