There is evidence for this effect in the widespread societal recognition of the cross as a cultural symbol of Christianity, the white dove as a symbol of peace, the Twin Towers as symbols of terrorism or, indeed, resilience, and the polar bear as a symbol of climate change (Turner, 1967;...

Thus, a shift operation needs to be carried out, which moves the origin of the Fourier transform to the central coordinates at the frequency domain. Low frequency components describe the most relevant information of the behavior of a signal. On the other hand, high frequency components are ...
of using nighttime images of lights on Earth, also known as nightlight (NTL), captured by the Visible Infrared Imaging Radiometer Suite (VIIRS) instrumentation onboard the Suomi National Polar-Orbiting Partnership (Suomi NPP) satellite mission to measure the economic cost of the pandemic in India....
Geffen et al.7reported that OFF ganglion cells can switch to ON polarity during and slightly after a sudden shift of a large grating present in the surround. Compared to our study, the change in that study was evoked by a transient and dynamical change in one stimulus property, while we ...
Mean shift clustering tends to generate accurate segmentations of color images, but choosing the scale parameters remains a difficult problem which has a s... I Gondra,X Tao - IEEE 被引量: 21发表: 2008年 Relevance Feature Mapping for Content-Based Image Retrieval This paper presents a ranking...

Prior to the verification, the images of each LTSS were clipped such that they had exactly the same spatial domain. 3.5.1 Image clipping As noted earlier, due to difficulties in orbital control, satellite orbits can shift slightly among repeat passes. As a result, several images for a single...
Such a data shift can arise when the model was trained on images captured with a particular fundus camera and tested on images from a second device. This inter-center heterogeneity in fundus images can be due to varying fields of view (FOV), color distribution, illumination, and area of ...
Since the focus is at a distance of millimeters away from the lens L4 and since the light needs to propagate back from the mirror to the lens, the condition of large distances (far field condition) is fulfilled. First, the plane wave in equation (10) is rewritten in polar coordinates as...
