The RPN works on the output feature map returned from the last convolutional layer shared with the Fast R-CNN. This is shown in the next figure. Based on a rectangular window of size nxn, a sliding window passes through the feature map. For each window, several candidate region proposals ...

Upsampling layers generally produce output features which depend locally on input features, and for receptive field computation purposes can be considered to have a kernel size equal to the number of input features involved in the computation of an output feature.[4]。)...
训练时出现ctc_loss_calculator.cc:144] No valid path found或loss: inf错误 熟悉CTC算法的话,这个提示应该是ctc没找到有效路径。既然是没找到有效路径,那肯定是label和input之间哪个地方又出问题了!和input相关的错误已经解决了,那么肯定就是label的问题了。再看ctc_batch_cost的四个参数,labels和label_length这两...
