Short Circuit Fault Detection against High Thermal Background Using a Two-Level Scheme Based on DoG Filter

Table 3

Serial numbers of the four short circuits determined by the orthogonal DoG filter and the DoG filter.

Real short circuit	1	2	3	4
Serial number (orthogonal DoG)	#10	#21	#23	#47
Serial number (DoG)	#10	#18	#20	#40
Real serial number	#9	#20	#22	#51
