landsat 7 etm+ data is widely used in studies of the spatial distribution kc and vegetation cover parameters in regional and global scales but slc failure has greatly reduces its usefulness. additionally, the failure is permanent and has failed subsequent attempts to recover the slc, so required and practical way to address this problem is filling the pixels of missed data in the slc-off images...

background: in myocardial perfusion spect imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. filters greatly affect quality of nuclear medicine images materials and methods: a phantom simulating heart left ventricle was built. about 1mci of 99mtc was injected into the phantom. images were taken from this phantom. some fi...

conclusions based on 8.2 mm cut-off point could differentiate 83% periapical granulomas and 79% radicular cysts from radiography images. background the distinction between radicular cysts and apical granulomas is important in treatment decision. objectives the current study aimed to differentiate these two lesions based on radiography images. results average size of radiography in periapical gr...

This paper offers an analysis of the meaning of although set within the framework of Relevance Theory. In line with Iten (1998b), although is seen as encoding procedural information that constrains the inferential processes involved in the derivation of implicatures. However, the current account differs from Iten (1998b) in several points. First, it suggests that utterances of the form Q althou...

The tilted viewing nature of the off-nadir aerial images brings severe challenges to building change detection (BCD) problem: mismatch nearby buildings and semantic ambiguity facades. To tackle these challenges, we present a multi-task guided network model, named as MTGCD-Net. proposed model approaches specific BCD problem by designing three auxiliary tasks, including: (1) pixel-wise classifica...
