1.安装 tesserocr，PIL(pip install pillow)
2.安装 Tesseract-OCR(最好将语言包全部下载)
3.将Tesseract-OCR下的tessdata复制到你的项目下的venv中Scripts下
实例：
'''
识别图片
'''
import tesserocr
from PIL import Image
#获得图片
img = Image.open('1.jpg')
img.show()
#图像灰度化处理
image = img.convert('L')
threshold = 125
table = []
for i in range(256):if i < threshold:table.append(0)else:table.append(1)
image = image.point(table, '1')
image.show()
#识别中文需指定语言集
#tesserocr.image_to_text(img,lang='chi_sim')
result = tesserocr.image_to_text(image)
print(result)'''

图像的滤波ImageFiter:
BLUR 模糊滤波
CONTOUR 轮廓滤波
DETAIL 细节滤波
EDGE_ENHANCE 边界增强滤波
EDGE_ENHANCE_MORE 边界增强滤波（程度更深）
EMBOSS 浮雕滤波
SHARPEN 锐化滤波
SMOOTH_MORE 平滑滤波（程度更深）
GaussianBlur(radius=2) 高斯模糊
