This paper presents a method to resize images by a rational factor of P/Q in the discrete cosine transform (DCT) domain where P and Q are relatively prime integers larger than one. Our method extends on the prior work of Mukherjee and Mitra which utilizes the spatial relationship of DCT coefficients between a block and its sub-blocks. To resize images by a factor of P/Q, the images are first up...

The article proposes a novel annotating method of sufficient capacity and intended not only on-line but for off-line using for information preservation all advantages of two-dimensional barcodes. The semantic annotations are embedded directly into the reasonably chosen area of the image and bound by spatial identifiers with corresponding regions. The embedding method deals with the different qu...
