Pascal VOC: Pascal VOC stores annotation in XML file. The annotations are stored using JSON.įor object detection, COCO follows the following format: annotation] Below are few commonly used annotation formats:ĬOCO: COCO has five annotation types: for object detection, keypoint detection, stuff segmentation, panoptic segmentation, and image captioning. There is no single standard format when it comes to image annotation.
In this post, we will look at the types of annotation for images, commonly used annotation format and some tools that you can use for image data labelling. It is very likely that you will have to go through the process of data annotation by yourself. If you can find a good open dataset for your project, that is labelled, LUCK IS ON YOUR SIDE! But mostly, this is not the case.

As a machine learning model learns in a similar way, by looking at examples, the result of the model depends on the labels we feed in during its training phase.ĭata labelling is a task that requires a lot of manual work. If you show a child a tomato and say its a potato, the next time the child sees a tomato, it is very likely that he classifies it as a potato. The same is true for annotations used for data labelling. Garbage In Garbage Out is a phrase commonly used in the machine learning community, which means that the quality of the training data determines the quality of the model.
