Output File Format

origin

Annotate's output is defined as a list of 2D points (i.e, Xi, Yi) to allow for any polygon representation. The annotations are stored in a text file with the format:

frameN: X1, Y1, X2, Y2, ... , Xn, Yn

where Xi and Yi are the coordinates of corner i of the polygon in frame N, the N-th row in the text file. In case of multiple annotations in a single frame a '|' character will be use as separator:

frameN: X11, Y11, X12, Y12, ... , X1n, Y1n |  X21, Y21, X22, Y22, ... , X2n, Y2n | X31, Y31, X32, Y32, ... , X3n, Y3n

where Xyi and Xyi are the coordinates of corner i of the polygon y in frame N.

The amount of points are defined by the type of annotations used in the sequence.

XML

You can also choose XML format as output format. The XML format take reference from ViPER XML. The format can be shown as:

<frame frameNumber="[frameNumber]">
	<box boxNumber="[boundingBoxNumber]" pointNumber:0="[X_0,Y_0]" pointNumber:1="[X_1,Y_1]" pointNumber:2="[X_2,Y_2]" pointNumber:3="[X_3,Y_3]"/>
</frame>

where [frameNumber] is the frame number starting from 0, [boundingBoxNumber] is the bounding box number starting from 0, [X_i,Y_i] are the coordinates of corner i of the bouding box [boundingBoxNumber] in frame [frameNumber].

Here is one example:

<frame frameNumber="0">
	<box boxNumber="0" pointNumber:0="60.000000,166.000000" pointNumber:1="164.000000,166.000000" pointNumber:2="164.000000,339.000000" pointNumber:3="60.000000,339.000000"/>
</frame>
