利用背景图片生成词云,设置停用词词集

最近研究了一下 如和利用背景图片生成词云,设置停用词词集

先上一波效果图 一个简单的 一个复杂的

It uses the average color of the regionoccupied by the word in a source image. You can combine this with masking -pure-white will be interpreted as 'don't occupy' by the WordCloud object whenpassed as mask.If you want white as a legal color, you can just pass a different image to"mask", but make sure the image shapes line up.你可以使用基于图像的颜色策略来为文字云上色在ImageColorGenerator中实现。它使用了该区域的平均颜色在源图像中被这个词占据。你可以把它和掩蔽-纯白色将被文字云对象解释为“不占用”通过面具。如果你想要白色作为合法颜色，你可以通过不同的图像“蒙版”，但要确保图像的形状是一致的。http://www.cnblogs.com/MnCu8261/p/5483657.html 关于oshttp://www.liaoxuefeng.com/wiki/001374738125095c955c1e6d8bb493182103fac9270762a000/00140767171357714f87a053a824ffd811d98a83b58ec13000实际上他是用来操作图片的 例如切片、旋转、滤镜、输出文字、调色板等一应俱全"""from os import path  # os.path.dirname(path)    #返回该路径的父目录from PIL import Imageimport numpy as npimport matplotlib.pyplot as pltfrom wordcloud import WordCloud, STOPWORDS, ImageColorGeneratord = path.dirname(__file__)# Read the whole text.text = open(path.join(d, 'test.txt')).read()#os.path.join(path,name)  #连接目录与文件名或目录 结果为path/name# read the mask / color image taken from# http://jirkavinse.deviantart.com/art/quot-Real-Life-quot-Alice-282261010alice_coloring = np.array(Image.open(path.join(d, "bj.jpg")))# 设置停用词stopwords = set(STOPWORDS)stopwords.add("navigation")# 你可以通过 mask 参数 来设置词云形状wc = WordCloud(background_color="white", max_words=2000, mask=alice_coloring,               stopwords=stopwords, max_font_size=40, random_state=42)# generate word cloud'generate 可以对全部文本进行自动分词,但是他对中文支持不好wc.generate(text)# create coloring from imageimage_colors = ImageColorGenerator(alice_coloring)# show# 在只设置mask的情况下,你将会得到一个拥有图片形状的词云plt.imshow(wc, interpolation="bilinear")plt.axis("off")plt.figure()wc.to_file('sy1.png')#将生成的实验图保存# recolor wordcloud and show# we could also give color_func=image_colors directly in the constructor# 我们还可以直接在构造函数中直接给颜色# 通过这种方式词云将会按照给定的图片颜色布局生成字体颜色策略plt.imshow(wc.recolor(color_func=image_colors), interpolation="bilinear")plt.axis("off")plt.figure()wc.to_file('sy2.png')plt.imshow(alice_coloring, cmap=plt.cm.gray, interpolation="bilinear")plt.axis("off")plt.show()
