Spectral methods have been extensively studied for point pattern matching. In this work, we aim to render the spectral matching algorithm more robust for positional jitter and outliers. We concentrate on the issue of spectral representation for point patterns. A local structural descriptor, called the line graph spectral context, is proposed to characterize the attribute of point patterns, making it fundamentally different from the available representation approaches at the global level.
