| 绿霸－花季护航”流氓软件的事情大家都已经知道了，鉴于所谓的国情，很多事情都不说也罢了。抛开政治因素以单纯的技术角度看这个软件，尤其令人诧异的是这个流氓软件对BSD软件许可证肆无忌惮的践踏和侵权！请看绿坝-花季护航软件技术分析。 请注意本文以下分析内容： 图像检测进程从待检图像队列中获取图像数据，先归一化图像尺寸，然后分离肤色区域和非肤色区域，在对肤色区域关系进行分析后去除干扰，提取区域的特征送入已训练SVM分类器。当图像被检为色情图像后送入人脸检测器，若人脸不是主要部分便确定为色情图像。这套算法的主要问题是，色情图像的识别严重依赖于肤色和肤色形状；而最后使用人脸检测加权判定也只是手工打补丁避免出现大幅人脸识别为色情图像问题的办法，且经验权值可靠性缺乏验证。 The process of image detection begins when visual data is obtaining as the image is in queue to be screened, first normalizing the image's size, then separating areas of skin tone from those without skin tone; analysis of the relationship between areas of skin tone is followed by removal of noises, then extraction of the area's characteristics, which are then input into a trained SVM classifier. Once the image has been deemed pornographic it is sent to a human face detector; if a human face is not the primary component, the image is then classified as pornography. The main problem with this algorithm is that recognition of pornographic images relies heavily on skin color and shape, and the final use of a human face detector in a weighted judgment is only a manual patch aimed at preventing the problematic occurrence of large faces being identified as pornography, but also the reliability of empirical weighting lacks verification. 从 XFImage.xml可观察到，绿霸使用了OpenCV的haar分类器进行人脸检测。绿霸附带的cximage.dll、CImage.dll、 xcore.dll和Xcv.dll也来自OpenCV的库文件。都反映出绿霸主要使用了OpenCV来进行图像方面的处理。不过就像一般国产软件的做 法，绿霸大概也无视了OpenCV的BSD许可证。 From XFImage.xml it can be observed that Green Dam uses OpenCV's Haar classifier in undergoing human face detection. Included with Green Dam, cximage.dll, CImage.dll, xcore.dll and Xcv.dll, also library files from OpenCV. This all suggests that Green Dam primarily uses OpenCV to process images. However, as is done with much of domestic Chinese software, Green Dam has disregarded OpenCV's BSD license. 不过就像一般国产软件的做法，绿霸大概也无视了OpenCV的BSD许可证。 OpenCV是什么软件呢？ 请看wikipedia：http://en.wikipedia.org/wiki/Opencv， OpenCV是Intel资助的开源计算机视觉库。它由一系列 C 函数和少量 C++ 类构成，实现了图像处理和计算机视觉方面的很多通用算法。OpenCV采用的是BSD license，对非商业应用和商业应用都是免费的。那么BSD有什么要求呢： BSD要求如果再发布的只是二进制类库/软件，则需要在类库/软件的文档和版权声明中包含原来代码中的BSD协议。 好了，事情说到这里就很清楚了，那么这个所谓的“滤霸－河蟹护航”软件发行包有没有BSD协议声明呢？显而易见了！更不可思议的事情是：这个用三方库和开源软件包拼凑起来的玩具竟然还在国家专利局申请了专利！ 我强烈呼吁OpenCV组织向这个流氓公司发出律师函，指控这个所谓的垃圾公司的侵权行为，让这个垃圾公司彻底关门。最令人不可以理解的是这个侵权的垃圾软件竟然通过了所谓的中国软件评测中心的所谓广泛的评测。我想我们应该理解为什么中国是一个软件盗版大国了。 原文地址：http://robbin.javaeye.com/blog/406125 |
