VOT-ST2020

[iremonur]

Hi, I want to evaluate a tracker on the VOT-ST2020 dataset. The segmentation annotations are placed under the gorundtruth.txt but I could not understand the format and find an explanation for it. For example, the annotation format is as in below:

m242,164,118,115,29,1,2,1,110,45,73,61,56,69,47,76,41,81,36,83,34,85,33,86,32,86,32,87,30,88,29,90,28,90,27,92,26,92,26,93,25,93,25,94,23,95,22,97,20,98,20,98,19,100,18,100,18,100,17,101,17,102,15,103,15,104,14,104,14,104,13,105,13,105,10,109,9,109,9,109,9,110,8,111,7,112,6,112,6,111,6,112,5,113,5,113,4,115,1,117,1,117,1,117,1,115,3,115,3,115,3,115,3,115,3,115,3,115,3,115,3,115,3,115,2,116,3,115,3,115,2,116,3,115,3,115,3,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,1,117,1,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,116,2,115,3,16,3,96,3,16,3,14,10,72,3,16,3,13,18,65,3,16,5,10,20,13,26,25,3,16,9,3,24,9,30,24,3,16,38,6,31,24,3,17,38,3,34,23,3,17,76,22,3,17,76,22,3,16,77,22,3,15,78,22,3,14,79,22,3,15,78,22,3,14,79,22,4,12,80,22,4,11,82,21,5,9,84,20,99,19,100,17,102,15,104,12,107,10,8

What does m242 mean? And what do these points represent? I assume that they represent the segmentation pixel points but are they ordered like x,y,x,y...x,y pixel coordinates? I tried to create binary segmentation masks considering they are ordered x,y.. but the mask obtained by these points does not represent the object. Could you please explain the annotation format for VOTSTS2022?
I would be glad if you help me with this.
