Mosaic techniques have been used to obtain images with a large field of view from video sequences by assembling individual overlapping images. In existing methods of mosaic construction only consecutive frames are aligned. Accumulation of small alignment errors occur, and in the case of the image path returning to a previous position in the mosaic (looping path), a significant mismatch between ...

This work investigates the complexity of one-dimensional cellular neural network mosaic patterns with spatially variant templates on finite and infinite lattices. Various boundary conditions are considered for finite lattices and the exact number of mosaic patterns is computed precisely. The entropy of mosaic patterns with periodic templates can also be calculated for infinite lattices. Further...

The cellular multiplicity of infection (MOI) is a key parameter for describing the interactions between virions and cells, predicting the dynamics of mixed-genotype infections, and understanding virus evolution. Two recent studies have reported in vivo MOI estimates for Tobacco mosaic virus (TMV) and Cauliflower mosaic virus (CaMV), using sophisticated approaches to measure the distribution of ...

G o l d i n (1963) found in Kazakhstan an interesting strain of tobacco mosaic virus (TMV). B r e a k (1978) established that this Kazakhstan strain (Ka strain) of TMV was defective and that it infected tobacco plants very slowly or the systemic infection was lacking. Its thermal inactivation point lay between 75 and 80° C. In fresh infective sap virus particles of normal length were found very...

Images are considered as one of the most important medium of conveying information, in the field of computer vision, by understanding images the information extracted from them can be used for other tasks. Image mosaic is the process of partitioning a digital image into multiple segments. Image de noising is done before the mosaic to avoid the selection of falsely object for mosaic to segment t...

Viral attacks on natural populations of herbaceous forage legumes might have adverse effect on seed and herbage production, hence this study was carried out to investigate the type and incidence of viruses occurring on these plants in Nigeria. Protein A-sandwich (PAS) and antigen-coated plate (ACP) enzyme-linked immunosorbent assays (ELISA) were used to detect ten legume viruses from 100 leaf s...

Aiming at the mosaic technology of the orthophoto acquired by Chinese remote sensing satellite CE-1, a thin-plate spline (TPS) function based method of image mosaic is proposed while the traditional mosaic method seems impossible. With the advantages of TPS (Thin-plate Spline) function in image transformer, the image fusion technology is introduced to get the seamless image mosaic result. Consi...

This paper presents results on mosaic-based visual navigation of an underwater autonomous vehicle, navigating close to the sea floor. A high-quality video-mosaic is automatically built to be used as a representation of the environment. A visual servoing strategy is adopted to drive the vehicle along a specified trajectory (indicated by waypoints) relative to the mosaic. The control errors are d...

Tobacco is widely planted across the world especially in China, which means that a large amount of tobacco waste needs to be treated. This study investigated the biogas fermentation of tobacco stalks co-digested with different biomass feedstocks and the inactivation of Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV) by anaerobic digestion. Results showed that the maximum methane yield o...
