When we are using an image transformer, why do we need a feature extractor (TrOCR processor is Feature Extractor + Roberta Tokenizer)?
And I saw the output image given by the processor, it’s the same as the original image, just the shape is changed, it resized smaller.
@nielsr  is the processor doing any type of image preprocessing ?.
I tried a few image preprocessing techniques like binarising the image, adding white space to borders, a bit of denoising and it turns out to be of little to no help.
Can you please comment on that too
