Abstract
Systems and methods for detecting text in videos. To address problems with conventional Optical Character Recognition (OCR) systems, the present disclosure provides detection of text for improved OCR. Aspects of the present disclosure can, therefore, be utilized to detect a textual logo in videos, including when the text of the textual logo is clearly visible and when the text is inferred. Thus, examples capture appearance time of a textual logo from a video view perspective. Aspects use a multi-threshold pipeline for detecting video frames including the textual logo. A textual-visual scoring system is additionally used to leverage visual aspects of text in logos. A shot detection system is used to detect inferred text beyond a detected video frame. One or more verification models can be further applied.
