java - 谷歌视觉 API : How to detect the image is painting image or real picture?

Question

我在检测图像时遇到问题，无论是绘画图像还是真实拍摄的照片。我查过 Google Vision REST-APIs 文档，似乎没有提到这一点。

如果您能分享如何检测它的算法，我们将不胜感激。

大多数时候，您可以搜索 JSON 响应的 webEntities 数组。我尝试使用你的第二张图片并得到以下结果:

"webEntities": [
  {
    "entityId": "/m/068jd",
    "score": 0.71919,
    "description": "Photograph"
  },
  {
    "entityId": "/m/04dtx9",
    "score": 0.71809,
    "description": "Flickr"
  },
  {
    "entityId": "/m/07glzq",
    "score": 0.71192,
    "description": "Sketch"
  },
  {
    "entityId": "/m/0k0pj",
    "score": 0.64715505,
    "description": "Nose"
  },
  {
    "entityId": "/m/01kr8f",
    "score": 0.41121,
    "description": "Illustration"
  },
  {
    "entityId": "/m/03c51f4",
    "score": 0.39885,
    "description": "Tagged"
  },
  {
    "entityId": "/m/01dv4h",
    "score": 0.37724,
    "description": "Portrait"
  },
  {
    "entityId": "/m/02csf",
    "score": 0.37219,
    "description": "Drawing"
  },
  {
    "entityId": "/m/0jjw",
    "score": 0.36841,
    "description": "Art"
  },
  {
    "entityId": "/m/03b19x",
    "score": 0.36128,
    "description": "Digital painting"
  },
  {
    "entityId": "/m/0mfx0",
    "score": 0.31653,
    "description": "Doodle"
  },

我认为除了在这些标签中搜索“paint”、“drawing”、“sketch”等单词之外，没有什么简单的方法可以做到这一点。
