本代码实现的是，在旋转10度的基础上，再进行增加对比度的操作。

1 代码:

代码注释中的代码都是可以运行的. 但是不怎么靠谱,因为文件名被逐个编辑,有可能与原标签不对应,,更好的做法参考代码2 # -*- coding: UTF-8 -*-

from PIL import Image

from PIL import ImageEnhance

import PIL.Image as img

from PIL import ImageEnhance

import os

def rotationImage(filepath,destpath):

count = 0

filelist=os.listdir(filepath) #所有文件的文件名

total_num=len(filelist) #所有文件的个数

print(total_num) #输出文件个数

for i in range(total_num): #对每张图像进行操作

print(count)

im=img.open(filepath+str(i+21)+str("_training")+".gif")

for j in range(72):

im_rotate=im.rotate(j*10) #每张图像都10°旋转一次

#然后对其增加亮度对比度等操作

enh_con=ImageEnhance.Contrast(im_rotate) #增加对比度 得到1440张

image_contrasted=enh_con.enhance(1.5)

image_contrasted.save(destpath + str("cont_") + str((j + 1) * 10) + str("_") + str(i + 21) + str("_") + str("manual1") + '.gif')

count=count+1

# enh_sha=ImageEnhance.Sharpness(im_rotate) #增加锐度

# image_sharped=enh_sha.enhance(3.0)

# image_sharped.save(destpath + str("sharp_") + str((j + 1) * 10) + str("_") + str(i + 21) + str("_") + str("training") + '.tif')

# enh_bri=ImageEnhance.Brightness(im_rotate) #增加亮度 但是有问题

# image_bright=enh_bri.enhance(1.5)

# image_bright.save(destpath + str("bri_") + str((j + 1) * 10) + str("_") + str(i + 21) + str("_") + str("training") + '.tif')

# enh_col=ImageEnhance.Color(im_rotate) #增加色度 但是有问题,

# image_colored=enh_col.enhance(1.5)

# image_colored.save(destpath + str("col_") + str((j + 1) * 10) + str("_") + str(i + 21) + str("_") + str("training") + '.tif')

更加靠谱的做法如下: # -*- coding: UTF-8 -*-

from PIL import Image

from PIL import ImageEnhance

import os

rootdir = r'/home/qxq/Desktop/eyedata_final/mask/original/' # 指明被遍历的文件夹

for parent, dirnames, filenames in os.walk(rootdir):

for filename in filenames:

currentPath = os.path.join(parent, filename)

im = Image.open(currentPath)

for j in range(72):

im_rotate = im.rotate(j * 10) # 每张图像都10°旋转一次

enh_con = ImageEnhance.Contrast(im_rotate) # 增加对比度 得到1440张(20*72=1440)

image_contrasted = enh_con.enhance(1.5)

newname1 = r"/home/qxq/Desktop/eyedata_final/mask/brighten/" + 'Cont_' + filename

image_contrasted.save(newname1)

enh_sha = ImageEnhance.Sharpness(im_rotate) # 增加锐度

image_sharped = enh_sha.enhance(3.0)

newname2 = r"/home/qxq/Desktop/eyedata_final/mask/brighten/" + 'sharp_' + filename

image_contrasted.save(newname2)

#

enh_bri = ImageEnhance.Brightness(im_rotate) # 增加亮度 但是有问题

image_bright = enh_bri.enhance(1.5)

newname3 = r"/home/qxq/Desktop/eyedata_final/mask/brighten/" + 'Bri_' + filename

image_contrasted.save(newname3)

#

enh_col = ImageEnhance.Color(im_rotate) # 增加色度 但是有问题,

image_colored = enh_col.enhance(1.5)

newname4 = r"/home/qxq/Desktop/eyedata_final/mask/brighten/" + 'Col_' + filename

image_contrasted.save(newname4)

j = 0
