In this paper, the geometric relationship between mosaic images for concentric panorama acquired by slit cameras along circular paths is considered. A concentric epipolar constraint is derived for mosaic images. It is shown how the concentric epipolar constraint can be used to calibrate the slit camera using point correspondences in two mosaic images. The concentric epipolar constraint is furth...

In the montane forest-grassland mosaics of Western Ghats, land cover conversion to silviculture and agriculture over last five decades has resulted in both loss natural habitats widespread invasion remnant habitat patches. While grassland mosaic been relatively well studied, there have few attempts understand extent which forest (locally known as sholas ) affected by spread exotic species. Here...

In the cold temperate zone of western and southern slopes Changbai Mountain, Betula ermanii Cham. forest, Picea jezoensis (Siebold & Zucc.) Carrière mixed forests B. P. are heterogeneously distributed in a mosaic patches, reason for this formation is still unclear. August 1986, typhoon disturbed on forming large number forest gaps. After more than 30 years vegetation succession, patches wind-st...

Transformer-based methods have recently achieved great advancement on 2D image-based vision tasks. For 3D video-based tasks such as action recognition, however, directly applying spatiotemporal transformers video data will bring heavy computation and memory burdens due to the largely increased number of patches quadratic complexity self-attention computation. How efficiently effectively model h...

Abstract Context Fire transforms, fragments and sometimes maintains forests, creating mosaics of burned unburned patches. Highly mobile animals respond to resources in the landscape at a variety spatial scales, yet we know little about their landscape-scale relationships with fire. Objectives We aimed identify drivers bat richness mosaic forested areas while identifying scales which was most st...

the dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. with the help of displacements and stresses green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...

Interstrain recombinants were observed in the progenies of the Cucumber mosaic virus (CMV) reassortant L(1)L(2)F(3) containing RNAs 1 and 2 from LS-CMV and RNA 3 from Fny-CMV. We characterized these recombinants, and we found that their fixation was controlled by the nature of the replicating RNAs 1 and 2. We demonstrate that the 2b gene partially affects this fixation process, but only in the ...

Determination of the structure of biological particles, randomly oriented in solution, from spatial correlation analysis of fluctuations in x-ray scattering has recently been proposed. The feasibility of scattering fluctuation measurements was evaluated by using an x-ray synchrotron radiation camera to obtain the spatial correlation for a solution of tobacco mosaic virus along a line. The exper...

Polyvalent mosaic HIV immunogens offer a potential solution for generating vaccines that can elicit immune responses against genetically diverse viruses. However, it is unclear whether key T cell epitopes can be processed and presented from these synthetic Ags and recognized by epitope-specific human T cells. In this study, we tested the ability of mosaic HIV immunogens expressed by recombinant...

Secret fragment visible mosaic image is proposed for combining small tiles of secret image to form a target image in the sense of mosaic. When this mosaic image is viewed at close, the observer can view smaller elements, but when viewed at a distance mosaic image is collection of tiles combined together to yield the overall picture. To generate a mosaic image, divide original image into many ti...
