- Without SSD (Single Shot MultiBox Detector): Accuracy can be lower than more recent two-stage detectors on complex datasets
- Without SSD (Single Shot MultiBox Detector): Primarily implemented in Caffe, which is less popular than PyTorch or TensorFlow today
- Without SSD (Single Shot MultiBox Detector): Limited support for very small object detection compared to newer models
- Without SSD (Single Shot MultiBox Detector): Requires GPU for optimal performance, limiting edge deployment
