摘要： Techniques for an image-based CAPTCHA for object recognition are described. The disclosure describes adding images to a database by collecting images by querying descriptive keywords to an image search engine or crawling images from the Internet.The disclosure describes generating the image-based CAPTCHA. The image is retrieved from the database, along with objects having significant values. An object is cropped from its image. The portion on the image where the object has been cropped is filled with image inpainting. The process obtains other objects from the database. The object is mixed among the other objects to form a set of candidate objects. A user is asked to select “the object” from the set of candidate objects that fits or matches the image. The image-based CAPTCHA evaluates whether a response, the selection, is from a human or a bot.

摘要翻译： 描述了用于对象识别的基于图像的CAPTCHA的技术。 本公开内容描述了通过向图像搜索引擎查询描述性关键词或从因特网爬行图像来收集图像来向图像数据库添加图像。 该公开内容描述了生成基于图像的CAPTCHA。 从数据库中检索图像以及具有重要值的对象。 一个物体从其图像中裁剪出来。 被裁剪对象的图像部分填充有图像修复。 该进程从数据库获取其他对象。 对象在其他对象之间进行混合以形成一组候选对象。 要求用户从适合或匹配图像的候选对象集中选择“对象”。 基于图像的CAPTCHA评估响应，选择是来自人还是机器人。
