WebOct 26, 2024 · Text detection helps identify the region in the image where the text is present. It takes in an image as an input, and the outputs bounding boxes. Text recognition extracts the text from the input image using the bounding boxes obtained from the text detection model. It takes in an image and some bounding boxes as inputs and outputs some raw … WebJun 5, 2024 · Instead of ignoring longer outputs than input sequences it just resturns this InvalidArgumentError(it seems that I did not correctly check the lengths of my sequences). So the solution for this is to preprocess your dataset and be sure that all the sequences that you are entering to the ctc_loss have more targets than inputs.
