In the distributed video coding, side information is involved not only in the decoding of the quantized source, but also in the reconstruction of the images. So the quality of side information takes an important role in the distributed video codec. In this paper, a refined approach to SI extraction is proposed. Based on the high correlation between the motion vectors of adjacent blocks, the motion...
Barcode extraction is an essential step in the 2D barcode reading architecture. This paper presents the development and evaluation of a new approach toward the design of 2D barcode extraction based on texture direction analysis. This new approach can be detailed as: i) threshold a gray-level image; ii) analyze the texture direction of a window which is selected within the barcode area in the image;...
