Python图像的增强处理操作示例【基于ImageEnhance类】

本文实例讲述了python图像的增强处理操作。分享给大家供大家参考，具体如下：

python中pil模块中有一个叫做imageenhance的类，该类专门用于图像的增强处理，不仅可以增强（或减弱）图像的亮度、对比度、色度，还可以用于增强图像的锐度。

具体见下面的例子：

				?

									#-*- coding: utf-8 -*-  

									from pil import image

									from pil import imageenhance

									#原始图像

									image = image.open('lena.jpg')

									image.show()

									#亮度增强

									enh_bri = imageenhance.brightness(image)

									brightness = 1.5

									image_brightened = enh_bri.enhance(brightness)

									image_brightened.show()

									#色度增强

									enh_col = imageenhance.color(image)

									color = 1.5

									image_colored = enh_col.enhance(color)

									image_colored.show()

									#对比度增强

									enh_con = imageenhance.contrast(image)

									contrast = 1.5

									image_contrasted = enh_con.enhance(contrast)

									image_contrasted.show()

									#锐度增强

									enh_sha = imageenhance.sharpness(image)

									sharpness = 3.0

									image_sharped = enh_sha.enhance(sharpness)

									image_sharped.show()
