标注人像轮廓

第2关：圈出人像轮廓

from PIL import Imagedef circle_out(path):        img = Image.open('./step2/white.jpg')    img = img.convert('RGB')    edge=[]    width,height = img.size    for h in range(0,height):        s=-1;e=-1        for w in range(0,width):            pix = img.getpixel((w,h))            if sum(pix)<3*240:                s=w-1                break        if w
   
    w:                pix = img.getpixel((w1,h))                if sum(pix)<3*240:                    e=w1+1                    break                w1=w1-1        edge.append([s,e])    # 请在此处编辑您的代码    #*********** Begin **********#    for i in range(len(edge)):        if (0<=edge[i][0]
   

替换背景色

from PIL import Imagedef ba_color(path):    img = Image.open(path)    img = img.convert('RGB')    edge=[]    width,height = img.size    for h in range(0,height):        s=-1;e=-1        for w in range(0,width):            pix = img.getpixel((w,h))            if sum(pix)<3*240:                s=w-1                break        if w
   
    w:                pix = img.getpixel((w1,h))                if sum(pix)<3*240:                    e=w1+1                    break                w1=w1-1        edge.append([s,e])    # 请在此处编辑您的代码    #*********** Begin **********#    for i in range(len(edge)):        if edge[i]==[-1,-1]:            for k in range(width):                img.putpixel((k,i),(255,0,0))        else:            for k in range(edge[i][0]+1):                img.putpixel((k,i),(255,0,0))            for k in range(edge[i][1],width):                img.putpixel((k,i),(255,0,0))    #*********** End **********#    img.save('./step3/结果/red.jpg')
