Aerial photogrammetry is one of the main methods obtaining geospatial information. After entering the 21st century, aerial photogrammetry technology has fully entered the digital age, and the quality of digital aerial photography results will directly affect the quality and accuracy of results of surveying and mapping .Therefore, it is necessary to inspect the quality of digital aerial photogra...

In recent years, several real-time or near real-time object detectors have been developed. However these object detectors are typically designed for first-person view images where the subject is large in the image and do not directly apply well to detecting vehicles in aerial imagery. Though some detectors have been developed for aerial imagery, these are either slow or do not handle multi-scal...

This study expands the limited understanding of pinniped aerial auditory masking and includes measurements at some of the relatively low frequencies predominant in many pinniped vocalizations. Behavioral techniques were used to obtain aerial critical ratios (CRs) within a hemianechoic chamber for a northern elephant seal (Mirounga angustirostris), a harbor seal (Phoca vitulina), and a Californi...

Image scene recognition is a core technology for many aerial remote sensing applications. Different landforms are inputted as different scenes in aerial imaging, and all landform information is regarded as valuable for aerial image scene recognition. However, the conventional features of the Bag-of-Words model are designed using local points or other related information and thus are unable to f...

Much work has been done in recent years to abstract computational models of human controlcomputational models of human control strategy (HCS) that are capable of accurately emulating dynamic human control behaviors. Land-based autonomous vehicles, both in simulation and on real roads, have made successful use of this modeling formalism. Little work has been done, however, in attempting such ski...

occurred on the plates, isolations were made from those areas to slants. None of the isolates formed aerial hyphae on glucose-asparagine agar. The interactions of the paired strains are given in table 1. For clarity, only reactions concerning the stimulation of aerial hyphae are reported. It is apparent that some strains could stimulate others, although unable themselves to form aerial hyphae; ...
