...On VOC2009 we have also run experiments where we have complemented the initial feature set with additional appearance and shape features — a bag of dense SIFT [68] features computed on the foreground mask, a bag of Local Shape Contexts [69] computed on its boundary, and a HOG pyramid [70] with3 levels computed on the bounding box fitted on the boundary of the segment, for a total of 1,054 features....

...To efficiently detect stable keypoint locations in scale space, we have proposed (Lowe, 1999) using scalespace extrema in the difference-of-Gaussian function convolved with the image, D(x, y, σ ), which can be computed from the difference of two nearby scales separated by a constant multiplicative…...
