The in-scene atmospheric compensation (ISAC) algorithm of Young et al. (2002) [14] (and as implemented in the ENVI software system [16] as ‘Thermal Atm Correction’) is commonly applied to thermal infrared multiand hyperspectral imagery (MSI and HSI, respectively). ISAC estimates atmospheric transmissivity and upwelling radiance using only the scene data. The ISAC-derived transmissivity and upwe...

background: the phenomenon of dust is a serious environmental problem in dry and semi dry regions. it has a destructive effect for the residents of such regions. over two-thirds of iran is in areas of dry and semi-dry climate conditions. methods: in this research, dust fall measurements were taken in 41 stations across yazd city using a marble dust collector (mdco) located in different parts of...

Collerton et al.’s Perception and Attention Deficit (PAD) model argues that all recurrent complex visual hallucinations (RCVH) result from maladaptive, deficient sensory and attentional processing. We outline a constructivist-based representation of perception using signal detection theory, in which hallucinations are modeled as false alarms when confirmational perceptual information is lacking...

Virtual reality (VR) represents a modern human-computer interface consisting of a three-dimensional (3D) environment generated by computer where the user can interact in different ways. VR can be applied in several applications domains such as medicine, education, entertainment, etc. In particular, interest is drawn to the application of VR in education since a student is able to interact and t...

This report accompanies the MaxD target detection algorithm implemented in the ENVI environment. The intent of the report is to describe the results obtained by using a provided AVIRIS test data set. Topics addressed include basic results on implementing the test data, how the test data set was processed and calibrated, and how the sensor response was applied. A brief analysis of results beyond...
