Ontology based complex object recognition
This paper presents an object categorization method. Our approach involves the following aspects of cognitive vision : machine learning and knowledge representation. A major element of our approach is a visual concept ontology composed of several types of concepts (spatial concepts and relations, color concepts and texture concepts). Visual concepts contained in this ontology can be seen as an ...
متن کاملOntology Based Object Learning and Recognition
This thesis deals with the problem of complex object recognition. The proposed approach takes place in the conceptual framework of cognitive vision. This thesis shows how an object categorization system is set up in three phases. The knowledge acquisition phase consists of acquiring domain knowledge as a taxonomy/partonomy of domain classes. It also consists of acquiring the visual description ...
متن کاملContent-based Image Retrieval by Ontology-based Object Recognition
The main disadvantage of image retrieval systems is their lack of domain knowledge. Therefore a retrieval system has to focus on primitive features, as Eakins and Graham name them [3]. Due to the lack of background knowledge of the domain, the retrieval error rate is usually dissatisfying or the search options are limited to syntactic queries. Knowledgebased techniques allow for semantical sear...
متن کاملObject Recognition based on Local Steering Kernel and SVM
The proposed method is to recognize objects based on application of Local Steering Kernels (LSK) as Descriptors to the image patches. In order to represent the local properties of the images, patch is to be extracted where the variations occur in an image. To find the interest point, Wavelet based Salient Point detector is used. Local Steering Kernel is then applied to the resultant pixels, in ...
متن کاملImage and 3D structure based ontology for object recognition
Image data is used constantly to express and convey information. Modern trends in technology and social media have made pictures a central part of human communication. However, the lack of semantic knowledge in image data severely limits its application. In this paper we present our research proposal for an improved object recognition method that uses semantic data over images that takes into c...
