Flag ignore_longer_outputs_than_inputs
Webignore_longer_outputs_than_inputs: Boolean. Default: False. If True, sequences with longer outputs than inputs will be ignored. time_major: The shape format of the inputs Tensors. If True, these Tensors must be shaped [max_time, batch_size, num_classes]. If False, these Tensors must be shaped [batch_size, max_time, num_classes]. Webthis way, the input going into ctc_loss has the exact required [ max_ts, batch, label] format. Also the results of using just 1 layer of conv is way superior to BiRNN (**for my data) ..also this post proved to be of immense intuitive help (for using convolutions with ctc_loss) How to use tf.nn.ctc_loss in cnn+ctc network

WebMay 29, 2024 · This is what we want, i.e. recognize the text present in the segments. So, what we will do is, pass each segment one-by-one to our text recognition model that will output the recognized text. In general, the Text Recognition step outputs a text file that contains each segment’s bounding box coordinates along with the recognized text.
