{}We introduce a method for expression invariant face recognition. A
generative 3D Morphable Model (3DMM) is used to separate identity and
expression components. The expression removal results in greatly increased
recognition performance, even on difficult datasets, without a decrease in
performance on expression-less datasets.
It is applicable to any kind of input data, and was evaluated here on
textureless range scans.

我想删除标题为“贡献”的框的背景颜色（淡黄色）。
我已阅读此帖子更改 baposter 中框的背景但我不认为它适用于我，因为我看不到任何称为“textborder”的东西
抱歉，这个问题太蠢了。谢谢
答案1
从baposter文档：
如您所见，plain模式使用bgColorOne您定义为bgColorOne=lighteryellow。将其更改为white，阴影将消失。或者将背景样式从 更改plain为none。
更新：更改文本背景
我在文档中找不到，但从中可以看出baposter.cls，框中文本的背景是用和baposter定义的。因此，在标题中或第二个参数中更改这些参数（见下文）以获得所需的结果：boxColorOneboxColorTwoposterheaderbox
\headerbox{Contribution}{name=contribution2,
column=0, row=0, span=4,
boxColorOne=green!30 %<--------------
}{
边注：
如果你刚开始baposter，也许你想尝试一下poster图书馆（来自tcolorbox) 使用与 类似的定位系统baposter，但文档更完善，并且提供一些其他选项，例如将文本从一个框移动到另一个框。这是一个很好的教程和这里一个例子
