State-of-the-art object detection networks depend on region proposal algorithms to hypothesize object locations. Advances like SPPnet [7] and Fast R-CNN [5] have reduced the running time of these detection networks, exposing region pro- posal computation as a bottleneck. In this work, we introduce a Region. Decide which R-CNN detector training function to use. To meet the above requirements a fully trainable Convolutional Neural Network (CNN) is used for the detection and recognition of speed signs.

Abstract—While deep learning based methods for generic object detection have improved rapidly in the last two years, most approaches to face detection are still based on the R-CNN framework [11], leading to limited accuracy and processing speed. In this paper, we investigate applying the Faster R-. CNN [26], which has. ... informed by global context in the image. It also makes predictions with a single network evaluation unlike systems like R-CNN which require thousands for a single image. This makes it extremely fast, more than 1000x faster than R-CNN and 100x faster than Fast R-CNN. See our paper for more details on the full system.

There is a huge amount of things affecting the speed of convergence of the model. Among others: The architecture of the network. The number of layers; The number of parameters in each layer; Activation functions used; Other architectural details. The dataset and the complexity of the problem; Learning. The loss function is less noisy than usual and does not oscillate for a few reasons. The main one is because you have only 1 category, so (to simplify a bit) the network is easily improving at each step, just by improving the score for that category on all your inputs. Take a look at the (beautiful !) image below: if you have. The original Faster R-CNN used ZF and VGG pretrained on ImageNet but since then there have been lots of different networks with a varying number of weights. For example, MobileNet, a smaller and efficient network architecture optimized for speed, has approximately 3.3M parameters, while ResNet-152. To meet the speed requirement of real-world applications, we further accelerate the proposed baseline model by layer decomposition and joint use of large-stride convolutional and deconvolutional layers. This also leads to a more general CNN framework that has a close relationship with the conventional Multi-Layer.

Fast-RCNN [12] on the usage of a CNN followed by a 4-step alternating training of the RPN and Fast-RCNN algorithms. The 4-step alternating training path consisted of first training an RPN off just the feature maps from the initial CNN, which already proves to be faster than training the RPN off the entire image.
