Question about the codes about std HOT 1 CLOSED

1. In lines 780 to 805, I am not sure if the variables in this section are being utilized, as it seems that the code is using the maximum of img_count_array[x_index][y_index] instead of the gradient (line 807 to 834). Can you please confirm if this section of the code is indeed being used?

Thanks for your attention.

1. The code is using the maximum of img_count_array[x_index][y_index] instead of the gradient. In our tests, these two worked fairly well. We also tried some other schemes (such as max distance etc.). The current corner point extraction strategy is a temporary version and is not continued to be used in our extended version.
2. When uncommenting the line in 856, the code will filter out corner points on the lines. But this step is still not stable enough, so it is not enabled.
