Verification mode

Hi,

We are working on a verification mode for LabelMe - please comment - in particular on the interpretation of the verified-element in the Label XML-format. Is there an XSD available?

---

When dealing with object recognition/classification, a way to fast and easily verify object classifications is often desirable.
A mode (‘v’) will be added to LabelMe in which it is possible to verify whether a given object is correctly classified or not.


When mode=v:
The objects in the annotation will be examined one after the other. The object in question (e.g. a car) will be framed by a polygon on the canvas. Instead of the object list, a verification tool will be presented on the right.
The verification tool will show an image example of what the classified class looks like (e.g. an image of a car) and a description of how the given class should be labelled. It will then be possible to verify, skip or reject the classification by using three buttons - or keyboard shortcuts. Upon each action, the verification tool proceeds to the next object (or image).

A new folder will be added (in addition to Images and Annotations): Classes
The Classes folder will contain example images and corresponding descriptions (HTML-snippets wrapped in XML) - e.g.:
Classes/car.jpg
Classes/car.xml
Classes/bike.jpg
Classes/bike.xml

The verification tool will exploit the existing verified-element in the XML-format, with values:
0 = not-examined
1 = verified
2 = rejected
3 = skipped (examined, but neither verified nor rejected).

Start by reviewing the existing annotation XML handling and the current annotation UI entry points; the issue names no files or tests. Clarify the verified-element semantics and whether an XSD exists, then define the mode=v workflow, Classes/car.* layout, and completion checks before implementation.
