Captions in videos often play an important role in video information indexing and retrieval. In this paper, we present a novel video caption detection approach. We first apply a new Multiple Frames Integration (MFI) method to minimize the variation of the background of the image. A time-based minimum (or maximum) pixel value search is employed and Sobel(More)
We propose a novel approach for auto image annotation. In our approach, we first perform the segmentation of images into regions, followed by clustering of regions, before learning the relationship between concepts and region clusters using the set of training images with pre-assigned concepts. Our main contribution is twofold. First, in the learning stage,(More)
Automatic image annotation has been intensively studied for content-based image retrieval recently. In this paper, we propose a novel approach for this task. Our approach first performs the segmentation of images into regions, followed by the clustering of regions, before learning the associations between concepts and region clusters using the set of(More)
