setting up code to rip a bbox out of a pyra
running hog pyra for regression test
testing scale calc
bbox slicing from pyra looks reasonable now. (in hog space... will test in convnet space soon)
working on only using pyramids and no on-demand features in DPM training. root_model() now updates spos{} to 'know' its root filter shape
first pass at precomputing features instead of warping
