Structure-Aware RGB Channel Reconstruction for YOLOv8-Based Oyster Mushroom Detection

Sonay Duman, Furkan Gözükara, Zekí Yetgín, Erdinç Avaroğlu

Short summary

Replacing raw RGB channels with grayscale, Sobel gradient, and a structural channel in YOLOv8s modestly improved oyster mushroom detection on a fixed split (555 images, 8282 instances), but performance dropped significantly on a chronological split, indicating input representation's influence without consistent robustness gains.
