YOLO (You Only Look Once)
Real-time object detection system, single neural network predicts bounding boxes and class probabilities directly from full images, high speed with reasonable accuracy.
Fast R-CNN
Improves upon the original R-CNN by sharing computation for different region proposals, uses ROI pooling to extract features, faster and more efficient than R-CNN.
Mask R-CNN
Extension of Faster R-CNN with pixel-level segmentation, provides high-quality object instance segmentation, more computationally expensive.
MobileNets
Lightweight deep neural networks for mobile and embedded vision applications, use depthwise separable convolutions for efficient performance, suitable for real-time object detection on mobile devices.
SSD (Single Shot MultiBox Detector)
Method for detecting objects in images using a single deep neural network, performs well on various object sizes, balances speed and accuracy.
EfficientDet
Scalable and efficient object detection model, uses a compound scaling method, achieves higher accuracy with fewer parameters and FLOPS compared to previous models.
Anchor-Free Object Detection
A category of methods that remove the need for predefined anchor boxes, detects object centers and directly regresses to bounding boxes, simplifies the detection pipeline.
RetinaNet
Employs a focal loss function to address class imbalance during training, achieves a good balance between speed and accuracy, can detect objects at multiple scales.
RCNN (Regions with Convolutional Neural Networks)
First framework to apply a deep neural network to object detection, highly accurate but slow due to the separate region proposal and detection stages.
Faster R-CNN
An advanced version of R-CNN, uses Region Proposal Networks (RPN) to generate potential bounding boxes in an image and to classify the objects, slower but more accurate than YOLO or SSD.
