Microsoft 计算机视觉 API 或 Google 的 Cloud Vision API 是否可以获取对象的位置? [英] Is it possible for either Microsoft Computer Vision API or Google's Cloud Vision API to get a location for objects?
问题描述
我正在尝试开发一个需要知道图像中标记对象位置的应用程序.知道图像中有钢琴"是不够的，我需要知道钢琴在图像中的位置.
I am trying to develop an application that needs to know the location of tagged objects in an image. Knowing that there is a "piano" in an image is not enough, I need to know where that piano is in the image.
Microsoft 的计算机视觉 API 和 Google 的 Cloud Vision API 都提供了某种形式的裁剪建议/智能缩略图生成服务，这让我认为正在检测某些对象的位置 - 但是有没有办法获取该信息(例如每个检测到的对象周围的边界框)来自 Microsoft 的计算机视觉 API 还是 Google 的 Cloud Vision API?
Both Microsoft's Computer Vision API and Google's Cloud Vision API provide some form of cropping suggestion/smart thumbnail generation service which leads me to think that the location of certain objects is being detected - however is there a way to get that information (like a bounding box around each detected object) from either Microsoft's Computer Vision API or Google's Cloud Vision API?
我知道这两个 API 都可以返回图像中检测到的人脸的位置，但是我正在寻找图像中每个对象的位置和大小:汽车、钢琴、树木、人...任何东西.
I understand that both APIs can return the location of faces detected in an image, however I am looking for locations and sizes of every object in an image: cars, pianos, trees, people...anything.
推荐答案
2020 更新:
这个问题已经有几年了，但是 Microsoft Azure 计算机视觉API 现在能够在图像中检测到的对象周围绘制边界框.这是一个 Python 示例.其他语言也可用.
This question is a few years old, but the Microsoft Azure Computer Vision API is now able to draw bounding boxes around objects that are detected in an image. Here is a sample in Python. Other languages are available as well.
