这个比较有创意。

传说中的猫脸检测，目测效果还不错。 应该写一个 C/C++ 版的。 {:3_189:}

http://harthur.github.com/kittydar/

Kittydar first chops the image up into many "windows" to test for the presence of a cat head. For each window, kittydar first extracts more tractable data from the image's data. Namely, it computes the Histogram of Orient Gradients descriptor of the image, using the hog-descriptor library. This data describes the directions of the edges in the image (where the image changes from light to dark and vice versa) and what strength they are. This data is a vector of numbers that is then fed into a neural network which gives a number from 0 to 1 on how likely the histogram data represents a cat.

The neural network (the JSON of which is located in this repo) has been pre-trained with thousands of photos of cat heads and their histograms, as well as thousands of non-cats. See the repo for the node training scripts.

这各人脸检测有什么区别吗？

有点意思，好像效果还不错，我传一张图，里面有一直狗还有一只很小的闭着眼睛的猫。成功识别，顺便问下，那位知道比较好的类似人脸识别的开源项目，C/C++的。很想学习下

    OpenCV 最大的优点就是 “OpenCV is released under a BSD license”。 {:3_189:}

    OpenCV 最大的缺点就是新算法比较少。 {:3_201:}

估计Ager的那些名猫是认不出来滴

呵呵，我家的猫倒不是名猫。。。但三只加菲猫，估计是无法被认出来了。。。

现在改许可证了么？

    还是 BSD license，但是最近有些算法加了专利警告，提示可能有专利问题。{:3_198:}
