Text Detection in Documents
A document vision task that locates text regions before character recognition is performed.
Text detection is the crucial localization stage that precedes recognition in OCR systems. Correctly identifying text blocks, lines, or word regions largely determines downstream recognition quality. This stage becomes especially important in complex layouts, visually rich reports, and multi-column documents. Without a strong text detection layer, OCR errors can rise rapidly.
