PASCAL VOC annotations were released in an XML format, where each image has an accompanying XML file describing the bounding box(es) contained in frame.įor example, in the BCCD dataset for blood cells detection, a single XML annotation example looks like as follows: (An aggregated PASCAL VOC dataset is available here.) We have an entire video on Pascal VOC XML on our YouTube. PASCAL annually released object detection datasets and reported benchmarks. From 2005 - 2012, PASCAL ran the Visual Object Challenge (VOC). PASCAL (Pattern Analysis, Statistical modelling and ComputAtional Learning) is a Network of Excellence funded by the European Union. Automatically Convert Annotation Formats PASCAL VOC XML Jump to the bottom of this post to see how. Roboflow generates COCO JSON, VOC XML, and others from any computer vision annotation format in three clicks. In this post we will give you the code necessary to convert between two of the most common formats: VOC XML and COCO JSON. As machine learning researchers leveraged these datasets to build better models, the format of their annotation formats became unofficial standard protocol(s). The most common annotation formats have emerged from challenges and amassed datasets. A data scientist spending time converting between annotation formats is like to an author spending time converting Word documents to PDFs. This creates frustrating situations where teams dedicate time to converting from one annotation format to another rather than focusing on higher value tasks – like improving deep learning model architectures. Object detection problems, specifically, require that items within frame are bounded in labeled annotations.Īs object detection has developed, different file formats to describe object annotations have emerged. Image Processing Problems, adapted from Stanford’s CS231N courseĬomputer vision problems require annotated datasets.
