A comprehensive method for multilingual video text detection, localization, and extraction

Semantic Based Sport Video Browsing

“…The text detection methods based on texture information usually assume that the text regions have special texture patterns. And the third is the edge density information [34], [68]. These methods make full use of the fact that the edge densities of background are comparatively sparser than those of the text regions [69], [70].…”

“…Video text detection and localization can be carried out both in pixel and compressed domains [71,34,68,65,72]. In order to eliminate false detections, the edge [69], texture [33], and shape information [57] are often utilized in text verifications.…”

“…In order to eliminate false detections, the edge [69], texture [33], and shape information [57] are often utilized in text verifications. In addition, the available redundant temporal information is often used in candidate text region verification and falsely detected text region elimination [71,34,68,65,72,73]. Lyu et al proposed a multiresolution based text detection method [34].…”

“…In addition, the available redundant temporal information is often used in candidate text region verification and falsely detected text region elimination [71,34,68,65,72,73]. Lyu et al proposed a multiresolution based text detection method [34]. Firstly, original edge map is generated for each of target video frames.…”

“…Text line number, spatial location, and temporal duration constraints are utilized during title text detection, localization and tracking. Lyu et al' method [34] is used to detect and localize title texts for a given frame.…”
