InstaBoost is a data augmentation technique for instance segmentation that utilises existing instance mask annotations.

Intuitively in a small neighbor area of (x0,y0,1,0)(x_0, y_0, 1, 0), the probability map P(x,y,s,r)P(x, y, s, r) should be high-valued since images are usually continuous and redundant in pixel level. Based on this, InstaBoost is a form of augmentation where we apply object jittering that randomly samples transformation tuples from the neighboring space of identity transform (x0,y0,1,0)(x_0, y_0, 1, 0) and paste the cropped object following affine transform H\mathbf{H}.
