What if the input examplar image is less than 127*127? #11

Hi, the tracker needs to resize the examplar image to 127127 and the next frame to 255255, however, if I want to track small object (e.g. less than 32*32), do you think is it possible? Or any hints on modifying the tracking code? Thanks.

Hi, There is no need to modify the code. If the object is smaller than 127x127 it will be simply upsampled to 127x127. In my experience the tracker works particularly well at low resolutions and with small objects, probably because in ImageNet Video (the training set) many objects are very tiny. Hope this helps.
