OpenCV HOGDescriptor返回值(OpenCV HOGDescriptor return value)

为什么HOG描述符返回float而不是int的向量? 它假设返回直方图..


Why does the HOG descriptor returns a vector of float and not int? It's suppose to return a histogram..

考虑更改您的locale 。 这对Rfacebook不是问题。 我可以通过将locale设置为C来复制您描述的行为,例如

x <- "Boa tarde. Há alguém de plantão na agência esses dias?"
Sys.setlocale(locale = "C")
x
# [1] "Boa tarde. H<U+00E1> algu<U+00E9>m de plant<U+00E3>o na ag<U+00EA>ncia esses dias?"

通过将字符集处理的区域设置切换为具有扩展字符集的区域设置,可以实现所需的输出,例如

Sys.setlocale(category = "LC_CTYPE", locale = "en_US.UTF-8")
x
# [1] "Boa tarde. Há alguém de plantão na agência esses dias?"

locale参数的值可能在您的系统上不同。 有关设置区域设置的更多信息,请参阅https://stat.ethz.ch/R-manual/R-devel/library/base/html/locales.html (或?locales )。


Consider changing your locale. It's not a problem with Rfacebook. I can replicate the behavior you described by setting locale to C, e.g.

x <- "Boa tarde. Há alguém de plantão na agência esses dias?"
Sys.setlocale(locale = "C")
x
# [1] "Boa tarde. H<U+00E1> algu<U+00E9>m de plant<U+00E3>o na ag<U+00EA>ncia esses dias?"

By switching the locale for character set handling to one with an extended character set, the desired output is achieved, e.g.

Sys.setlocale(category = "LC_CTYPE", locale = "en_US.UTF-8")
x
# [1] "Boa tarde. Há alguém de plantão na agência esses dias?"

The value of the locale argument may be different on your system. See https://stat.ethz.ch/R-manual/R-devel/library/base/html/locales.html (or ?locales) for more information on setting locales.
