Get ready1. Bluetooth serial port based on SPP protocol (Serial Port profile), can create serial port between Bluetooth devices for data transmission2.SPP of UUID:00001101-0000-1000-8000-00805F9B34FB3.Android mobile phones Generally actively connect the SPP protocol device t

The running of the CSR Bluetooth Chip SPP service is the PS setting, csrspp The CSR Bluetooth chip directly runs the built-in spp_dev_ B example program. The host cannot search for Bluetooth devices, mainly because the PS key value needs to be configured as follows: // PSKEY_BDADDR Amp; 0001 = 0011 2003 0003 0014 // P

full-join layer, it is necessary to strictly ensure that the input proposal eventually resize to the same scale size, which causes image distortion to a certain extent and affects the final result.2.

This article is for you to interpret spp-net: Spatial Pyramid Pooling in deep convolutional Networks for Visual recognition MotivationThe success of neural network in computer vision is due to convolutional neural networks, however, many of the existing successful neural network structures require input into a fixed size (such as 224x224,299x299), the introduction of an image, it needs to be stretched or clipped, and then input into the

Original from: http://blog.csdn.net/xzzppp/article/details/51377731 Reference paper: Spatial pyramid Pooling in Deep convolutional Networks for Visual recognition A brief introduction to the reference paper 1. Introduction The spatial pyramid pooling makes it possible for any size feature map to be converted to a fixed size eigenvector, which is the significance of the spatial pyramid pooling (the Multi-scale feature extracts a fixed size eigenvector) and is fed into the fully connected layer.

input image size caused by the defects. Second: Because of a feature map from different angles of feature extraction, and then the characteristics of aggregation, showing the robust characteristics of the algorithm. Third: It also adds precision to the object recongtion. In fact, you can think of this, the most cattle break the place is because in the back of the convolution layer of each picture has been a multi-faceted feature extraction, he can improve the accuracy of the task.
