myRproj

一些关于R使用的练习和想法

face

以国家领导人的脸为例,使用R尝试图像分析

CloudAtlas

以《云图》在豆瓣的500篇影评为例,使用Package:topicsmodel建立主题模型

longmen

以《龙门镖局》在豆瓣的324篇影评为例,使用package:RTextTools进行文本分类

MVC

用R实现MVC(Mean-value Coordinates)图像编辑算法,Possion图像编辑的近似算法,论文见Coordinates for Instant Image Cloning。这里并没有要求严格的轮廓边界点,仅用矩形框代替轮廓。

MVC算法要求背景不能太复杂,否则效果太差。图像编辑主要通过手动三分图实现,比如Photoshop,自动实现三分图还是比较困难的,效果还不一定好。

ChinaMovie

关于10855部**电影的简单分析,数据来自豆瓣电影。
