Qualitative detection results of the proposed model on the TLFO test set. The three examples (a–d) cover different transmission-line scenes and foreign-object types (nests, kites, balloons, trash). Coloured bounding boxes denote the four target categories, illustrating that the detector can localise small, low-contrast objects in the presence of complex background structures.
