This paper shows results from our development of an extended MATLAB image processing toolbox, which implements some useful optical image processing and mosaicking algorithms found in the literature. We surveyed and selected algorithms from the field which showed promise in application to the underwater environment. We then extended these algorithms to explicitly deal with the unique constraints...
Image-based rendering is one of the hottest new areas in computer graphics. Instead of using 3D modeling and painting tools to construct graphics models by hand, IBR uses real-world imagery to rapidly create photorealistic shape and appearance models. However, IBR results to date have mostly been restricted to static objects and scenes. Videobased rendering brings the same kind of realism to co...
since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...
Target recognition systems using Synthetic Aperture Radar (SAR) data require well-focused target imagery to achieve high probability of correct classification. Techniques for improving the image quality of complex SAR imagery are investigated. The application of phase gradient re-focusing of target imagery having crossrange smearing is shown to significantly improve the target recognition perfo...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Cloud-free optical satellite imagery simplifies remote sensing, but land-cover phenology limits existing solutions to persistent cloudiness to compositing temporally resolute, spatially coarser imagery. Here, a new strategy for developing cloud-free imagery at finer resolution permits simple automatic change detection. The strategy uses regression trees to predict pixel values underneath clouds...
Unmanned aircraft have decreased the cost required to collect remote sensing imagery, which has enabled researchers to collect high-spatial resolution data from multiple sensor modalities more frequently and easily. The increase in data will push the need for semantic segmentation frameworks that are able to classify non-RGB imagery, but this type of algorithmic development requires an increase...
The Digital Imaging and Remote Sensing Image Generation (DIRSIG) model enables a user to generate synthetic scenes. With this package these scenes can span anywhere between 0.3-20 microns and encompass an array of spatial and spectral phenomena. One project facilitated by DIRSIG is mega-scene. In the megascene project projection of aerial imagery is used as a texture map. After scene rendering ...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
A new fused Bayesian maximum entropy–variational analysis (BMEVA) method for enhanced radar/synthetic aperture radar (SAR) imaging is addressed as required for high-resolution remote sensing (RS) imagery. The variational analysis (VA) paradigm is adapted via incorporating the image gradient flow norm preservation into the overall reconstruction problem to control the geometrical properties of t...
