Multiview image sequence processing has been the focus of considerable attention in recent literature. This paper presents an efficient technique for object-based rigid and non-rigid 3D motion estimation, applicable to problems occurring in multiview image sequence coding applications. More specifically, a neural network is formed for the estimation of the rigid 3D motion of each object in the scene,...
The present paper proposes a hybrid content-based image search and retrieval technique based on the use of the DC coefficient information and the Encoding Cost Map (ECM), extracted from compressed JPEG data. The proposed scheme combines color-based indexing of the DC DCT coefficient data with shape-based indexing of the ECM. The use of ECM along with the information carried in the DC DCT coefficients...
