本文实例为大家分享了Python将图片彩色转化为素描的具体代码，供大家参考，具体内容如下

第一种：

from PIL import Image, ImageFilter, ImageOpsimg = Image.open('E:\\picture\\1.png')def dodge(a, b, alpha): return min(int(a*255/(256-b*alpha)), 255)def draw(img, blur=25, alpha=1.0): img1 = img.convert('L') #图片转换成灰色 img2 = img1.copy() img2 = ImageOps.invert(img2) for i in range(blur): #模糊度 img2 = img2.filter(ImageFilter.BLUR) width, height = img1.size for x in range(width): for y in range(height): a = img1.getpixel((x, y)) b = img2.getpixel((x, y)) img1.putpixel((x, y), dodge(a, b, alpha)) img1.show() img1.save('E:\\picture\\10.png')draw(img)

第二种：

from PIL import Imageimport os # 图像组成：红绿蓝 （RGB）三原色组成 亮度（255,255,255）image = "E:\\picture\\123.png"img = Image.open(image)img_all = "E:\\picture\\1234.png"new = Image.new("L", img.size, 255)width, height = img.sizeimg = img.convert("L")# print(img.size)# print(img.mode) #RBG## img_get = img.getpixel((0, 0))# print(img_get) #三原色通道## img_L=img.convert('L')# print(img_L)# img_get_L=img_L.getpixel((0,0)) #换算 得到灰度值# print(img_get_L) # 定义画笔的大小Pen_size = 3# 色差扩散器Color_Diff = 6for i in range(Pen_size + 1, width - Pen_size - 1): for j in range(Pen_size + 1, height - Pen_size - 1): # 原始的颜色 originalColor = 255 lcolor = sum([img.getpixel((i - r, j)) for r in range(Pen_size)]) // Pen_size rcolor = sum([img.getpixel((i + r, j)) for r in range(Pen_size)]) // Pen_size # 通道----颜料 if abs(lcolor - rcolor) > Color_Diff: originalColor -= (255 - img.getpixel((i, j))) // 4 new.putpixel((i, j), originalColor) ucolor = sum([img.getpixel((i, j - r)) for r in range(Pen_size)]) // Pen_size dcolor = sum([img.getpixel((i, j + r)) for r in range(Pen_size)]) // Pen_size # 通道----颜料 if abs(ucolor - dcolor) > Color_Diff: originalColor -= (255 - img.getpixel((i, j))) // 4 new.putpixel((i, j), originalColor) acolor = sum([img.getpixel((i - r, j - r)) for r in range(Pen_size)]) // Pen_size bcolor = sum([img.getpixel((i + r, j + r)) for r in range(Pen_size)]) // Pen_size # 通道----颜料 if abs(acolor - bcolor) > Color_Diff: originalColor -= (255 - img.getpixel((i, j))) // 4 new.putpixel((i, j), originalColor) qcolor = sum([img.getpixel((i + r, j - r)) for r in range(Pen_size)]) // Pen_size wcolor = sum([img.getpixel((i - r, j + r)) for r in range(Pen_size)]) // Pen_size # 通道----颜料 if abs(qcolor - wcolor) > Color_Diff: originalColor -= (255 - img.getpixel((i, j))) // 4 new.putpixel((i, j), originalColor) new.save(img_all) i = os.system('mshta vbscript createobject("sapi.spvoice").speak("%s")(window.close)' % '您的图片转换好了')os.system(img_all)

如果报错

可以直接安装
命令pip install Pillow即可
