An image retrieval system based on name of person/place which reflected in news video images is required to utilize archived videos. One of the techniques to realize the system is a scene text recognition technique which can recognize a text written on signs and name tags. We propose a robust method of detecting multi-oriented scene text candidate by using a rotated-aspect ratio feature. Moreover, we define a rotated bounding box descriptor to fast find the rotated-aspect ratio.
