Data augmentation is applied both geometrically and in terms of intensity. Geometrically, the images are mirrored, flipped, rotated, and randomly cropped. For intensity augmentation, random noise is added, and random masking is applied. Finally, a square matrix (GT matrix) is used to represent the correspondence of matching points between the two images. The GT_matrix is a square matrix of <i>N</i> × <i>N</i> dimensions. <i>GT</i> ( <i>i</i> , <i>j</i> ) represents the element of the <i>i</i>th row and the <i>j</i>th column in the GT matrix. The shown input image pairs take optical and SAR image pairs as an example.
