=== Add-on techniques ===
Instead of modifying existing methods, some add-on techniques are there, which can be directly placed on top of existing approaches to detect smaller objects. One such technique is Slicing Aided Hyper Inference(SAHI).<ref>{{cite arXivbook |last1=Akyon |first1=Fatih Cagatay |last2=Altinuc |first2=Sinan Onur |last3=Temizel |first3=Alptekin |date=2022-07-12 |title=2022 IEEE International Conference on Image Processing (ICIP) |chapter=Slicing Aided Hyper Inference and Fine-tuningTuning for Small Object Detection |classpages=cs966–970 |doi=10.1109/ICIP46576.2022.CV9897990 |eprintarxiv=2202.06934|isbn=978-1-6654-9620-9 |s2cid=246823962 }}</ref> The image is sliced into different-sized multiple overlapping patches. [[Hyperparameter (machine learning)|Hyper-parameters]] define their dimensions. Then patches are resized, while maintaining the aspect ratio during fine-tuning. These patches are then provided for training the model.
