美白,磨皮,搞笑图片处理

PIL库是一个支持图像存储、显示和处理的函数库,它能够处理几乎所有图像格式,可以完成对图像的缩放、裁剪、叠加以及图像添加条纹,文字等信息等的操作。

首先是利用pip下载一个:

 

它有许多子库,例如:Image、ImageChops、ImageDraw等等,他们各有神通,发挥着自己的作用,

首先我们当然学习的是经典的Image子库:

 

 

方法 描述
Image.open(filename) 根据参数加载图像文件
Image.new(mode,size,color) 根据给定参数创建一个新的图像
Image.frombytes(mode,size,data) 根据像素点data创建图像
Image.verify() 对图像文件完整性进行检查,返回异常

图像可视化:

from PIL import Image
im = Image.open("C:\\Users\\ZK\\Desktop\\test1.jpg") # 读取图片
im.show() # 可视化

效果如下:

灰度化h

灰度化:

from PIL import Image
img = Image.open("C:\\Users\\ZK\\Desktop\\test2.jpg")
# 灰度化:将RGB/RGBA -> L
img = img.convert("L")
img.show()

原图:

效果如下:

美白磨皮:

from PIL import Image
from PIL import ImageEnhance
import cv2
import numpy as np
 
 
# image = Image.open("C:\\Users\\ZK\\Desktop\\test1.jpg")
#image.show()
def BrightnessEnhancement(brightness):
    image = Image.open("C:\\Users\\ZK\\Desktop\\test1.jpg")
    enh_bri = ImageEnhance.Brightness(image)
#    brightness =1.5
    image_brightened = enh_bri.enhance(brightness)
    image_brightened.show()
 
def ContrastEnhancement(contrast):
    image = Image.open("C:\\Users\\ZK\\Desktop\\test1.jpg")
    enh_con = ImageEnhance.Contrast(image)
#    contrast =1.5
    image_contrasted = enh_con.enhance(contrast)
    image_contrasted.show()
 
def ColorEnhancement(color): 
    image = Image.open("C:\\Users\\ZK\\Desktop\\test1.jpg")
    enh_col = ImageEnhance.Color(image)
#    color =0.8
    image_colored = enh_col.enhance(color)
    image_colored.show()
 
def SharpnessEnhancement(sharpness):
    image = Image.open("C:\\Users\\ZK\\Desktop\\test1.jpg")
    enh_sha = ImageEnhance.Sharpness(image)
#    sharpness = 2
    image_sharped = enh_sha.enhance(sharpness)
    image_sharped.show()
 
def Filter(image):
    image =cv2.imread("C:\\Users\\ZK\\Desktop\\test1.jpg")
    Remove=cv2.bilateralFilter(image,0,0,10)
    cv2.imshow('filter',Remove)
    cv2.waitKey(0)
    cv2.destroyAllWindows()
#    res = np.uint8(np.clip((1.2 * image + 10), 0, 255))
#    tmp = np.hstack((dst, res)) 
#    cv2.imshow('bai',res)
 
 
def WhiteBeauty(image,whi):
    image =cv2.imread("C:\\Users\\ZK\\Desktop\\test1.jpg")
    white = np.uint8(np.clip((whi * image + 50), 0, 255))
    cv2.imshow('bai',white)
    cv2.waitKey(0)
    cv2.destroyAllWindows()
 
 
if __name__ =="__main__":
    filepath = "C:\\Users\\ZK\\Desktop\\test1.jpg"
    #原始图像
    brightness = 1.5
    contrast = 0.2
    color=1.9
    sharpness=0.1
    BrightnessEnhancement(brightness)
    ContrastEnhancement(contrast)
    ColorEnhancement(color)
    SharpnessEnhancement(sharpness)
    whi = 1.2
    image =cv2.imread("C:\\Users\\ZK\\Desktop\\test1.jpg")
    Filter(image)
    WhiteBeauty(image,whi)
