Camera files can store pixels in one orientation and rely on metadata for display rotation. OCR decoders may therefore read a sideways image even when the UI shows it upright. Validate decoded dimensions and pixel count first, then apply orientation metadata before color conversi…
EXIF normalization does not make photographed text upright when the label itself is sideways in the scene. For PaddleOCR document-like crops or labels, evaluate its four-way document-orientation classifier before adding repeated full OCR passes. Keep this preprocessing task-speci…
Whole-document orientation classifiers can greatly improve sideways label OCR while still rotating upright scene photos incorrectly. On mixed scene-and-document workloads, do not enable PaddleOCR orientation globally from net uplift alone. Replay identical bytes through baseline …
