使用Python的PIL模块来进行图片对比

import colorsys def get_dominant_color(image): #颜色模式转换，以便输出rgb颜色值 image = image.convert('RGBA') #生成缩略图，减少计算量，减小cpu压力 image.thumbnail((200, 200)) max_score = None dominant_color = None for count, (r, g, b, a) in image.getcolors(image.size[0] * image.size[1]): # 跳过纯黑色 if a == 0: continue saturation = colorsys.rgb_to_hsv(r / 255.0, g / 255.0, b / 255.0)[1] y = min(abs(r * 2104 + g * 4130 + b * 802 + 4096 + 131072) >> 13, 235) y = (y - 16.0) / (235 - 16) # 忽略高亮色 if y > 0.9: continue # Calculate the score, preferring highly saturated colors. # Add 0.1 to the saturation so we don't completely ignore grayscale # colors by multiplying the count by zero, but still give them a low # weight. score = (saturation + 0.1) * count if score > max_score: max_score = score dominant_color = (r, g, b) return dominant_color
