An Invariant Tangent-Angle Descriptor and a Band U-Net for 2D Fragment Adjacency Prediction
This paper addresses the prediction of adjacency between pairs of 2D fragments based on their contours. We improved the two-stage architecture proposed in Beaulac's thesis, in which a rotation-equivariant Siamese convolutional neural network scores pairs of local image windows along the two contours of two fragments.
