This paper proposes an automatic extraction method of target objects from images based on the support vector data description (SVDD) for image retrieval.
From training images including and not including target objects, the proposed method enables their automatic extraction.
Specifically, probabilities which feature vectors of local areas belong to the object class is defined based on distances from center of the hypersphere, and positive areas including target objects and negative areas not including these objects can be obtained from the training images based on the probabilities.
In this scheme, in order to obtain the hypersphere which can separate the positive areas and the negative ones more accurately, the feature vectors are selected adaptively.
Furthermore, by iterating the calculation of the hypersphere and the extraction of the positive areas and the negative ones in various sizes, the detection of target objects in images can be realized without manually extracting areas of target objects.
Therefore, image retrieval based on object extraction can be expected. |
