Instance segmentation, an important image processing operation for automation in agriculture, is used to precisely delineate individual objects of interest within images, which provides foundational information various automated or robotic tasks such as selective harvesting and precision pruning. This study compares the one-stage YOLOv8 two-stage Mask R-CNN machine learning models instance segmentation under varying orchard conditions across two datasets. Dataset 1, collected dormant season, includes images apple trees, were train multi-object delineating tree branches trunks. 2, early growing canopies with green foliage immature (green) apples (also called fruitlet), single-object only apples. The results showed that performed better than R-CNN, achieving good near-perfect recall both datasets at a confidence threshold 0.5. Specifically, achieved 0.90 0.95 all classes. In comparison, demonstrated 0.81 same dataset. With 0.93 0.97. this single-class scenario, 0.85 0.88. Additionally, inference times 10.9 ms multi-class (Dataset 1) 7.8 2), compared 15.6 12.8 by R-CNN's, respectively. These findings show YOLOv8's superior accuracy efficiency applications models, specifically Mask-R-CNN, suggests its suitability developing smart operations, particularly when real-time are necessary cases fruit thinning.

Considering precision agriculture, recent technological developments have sparked the emergence of several new tools that can help to automate agricultural process. For instance, accurately detecting and counting apples in orchards is essential for maximizing harvests ensuring effective resource management. However, there are intrinsic difficulties with traditional techniques identifying orchards. To identify, recognize, detect apples, apple target detection algorithms, such as YOLOv7, shown a great deal reflection accuracy. But occlusions, electrical wiring, branches, overlapping pose severe issues precisely apples. Thus, overcome these recognize find depth from drone-based videos complicated backdrops, our proposed model combines multi-head attention system YOLOv7 object identification framework. Furthermore, we provide ByteTrack method real time, which guarantees monitoring verify efficacy suggested model, thorough comparison assessment performed current techniques. The outcomes adequately proved effectiveness strategy, continuously surpassed competing methods achieve exceptional accuracies 0.92, 0.96, 0.95 respect precision, recall, F1 score, low MAPE 0.027, respectively.
