HOG descriptors are used for object detection.
Such system might be used for imaging phase objects and is especially important for imaging biological systems.
To characterize the response properties of MUs and single cells isolated from MUs, we recorded evoked responses to 100 object images that included 20 object images used for intrinsic signal imaging.
First, because the stimuli used in intrinsic signal imaging were involved in 100 object images examined for individual cells in the spots, correlation coefficients calculated for 100 object images may be biased to 20 object images used for intrinsic signal imaging.
Thus, the APSF acquisition does not require any modifications of the imaging system, is stable, and most importantly, it is representative for object imaging under the same conditions.
The following configurations were used for imaging the test object and anthropomorphic phantom: 64 × 0.5 mm (number of active detector rows × detector row width), rotation time 0.5 s and pitch factor 0.823.
EISCAT_3D can also be used for imaging solar system objects.
Electrical capacitance tomography (ECT) is an imaging technique commonly used for imaging dielectric permittivity of insulating objects.
Cellular objects that are more closely spaced than half the wavelength of light used for imaging cannot be visually resolved as separate objects using single channel fluorescence microscopy.
One technology commonly used for imaging the inside of the body, especially soft tissues such as the brain, is magnetic resonance imaging (MRI).
