Your Cartoon Face

这是一个基于paddlehub的项目。（疯狂安利aistudio，Tesla V100警告

本项目的功能是：输入一个人的照片，输出这个人的漫画风格脸。

本项目分为两部分，第一部分，检测出图片中的人脸，并进行裁剪。第二部分，将检测出的人脸变成漫画风格的人脸。

Part 1. 人脸检测

import matplotlib.pyplot as plt
import cv2
import numpy as np
import paddlehub as hub

先看一看输入图片

img_path = ['./data/hp.jpg']
img = cv2.imread(img_path[0])
img = cv2.cvtColor(img, cv2.COLOR_RGB2BGR)
plt.figure(figsize=(10, 10))
plt.imshow(img)
plt.show()

加载face dectector预训练模型

face_detect_module = hub.Module(name='ultra_light_fast_generic_face_detector_1mb_640')
input_dict = {'image': img_path}
results = face_detect_module.face_detection(data=input_dict)
print(results[0])
data = results[0]['data'][0]
top = max(int(data['top']-20), 0)
bottom = min(int(data['bottom']+20), img.shape[0])
left = max(int(data['left']-20), 0)
right = min(int(data['right']+20), img.shape[1])
img = img[top:bottom, left:right]
plt.figure(figsize=(10, 10))
plt.imshow(img)
plt.show()
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
cv2.imwrite('./data/hp2.jpg', img)

Part 2. Style Transfer

(由于用的普通的预训练gan，transfer效果一般般，留下了菜鸡的眼泪)

看一看风格图片

style_img = cv2.cvtColor(cv2.imread('data/C00003.jpg'), cv2.COLOR_RGB2BGR)
plt.figure(figsize=(10, 10))
plt.imshow(style_img)
plt.show()

加载style transfer模型

stylepro_artistic = hub.Module(name="stylepro_artistic")
result = stylepro_artistic.style_transfer(
    images=[{
        'content': cv2.cvtColor(cv2.imread('data/hp2.jpg'), cv2.COLOR_RGB2BGR),
        'styles': [cv2.cvtColor(cv2.imread('data/C00003.jpg'), cv2.COLOR_RGB2BGR)]
    }])
cartoon_img = result[0]['data']
plt.figure(figsize=(10, 10))
plt.imshow(cartoon_img)
plt.show()
