A New Method for Detecting and Locating Captions in Video Images
Ronggui Wang · Acta Simulata Systematica Sinica · 2002
The usual color histogram of a digital image can not describe the local features and object attributes of the image. The paper presents a kind of new color histogram, which has the ability of describing local features. The definition of it is given, and the mapping relation is analyzed between its trait areas and image captions. Then, the application of the new color histogram is discussed, and an algorithm is proposed for rapidly detecting and locating captions in an image. In the end, computing experimental results are given and the validity of the algorithm is shown.
