[FishBigOcean]

Motivation

fix and op bug

Modification

ind = list(vg > vis_thr) and list(vd > vis_thr)
change to
ind = list((vg > vis_thr) & (vd > vis_thr))
In python a non-empty array is considered true, so the previous statement becomes
ind = true and list(vd > vis_thr)

BC-breaking (Optional)

Use cases (Optional)
