Hey, both of the pages answer on is steps after some text detected right? https://i.pinimg.com/564x/bd/a3/d4/bda3d4bf11b0f727db1f9d81faac1b5d.jpg i have all this type of images where I am not able to detect date at the top right. also contact name, phone, fax this is not correctly read every time or missed in detection part. That's the reason i am asking i have a similar format of the document so if i trained the model on that it will help the model in the detection and recognition part? I don't know how tesseract detecting the text from the whole form. i have tried thresholding, scaling, sharpening but this can't give me results all time.
