a, c CTAC images, with circular regions of interest matching with the VOIs (in red).
(b) Selective formation of porous silicon in circular regions in subsequent electrochemical etching in HF electrolyte.
The cities are represented as filled circular regions, roads with solid black lines, and railroads with solid brown lines.
Circular regions of interest (ROIs) were drawn onto the hot spheres, on the widest slice of the sphere.
In [13], a scheme is described that involves image segmentation, Gaussian scale model and moment normalization of selected circular regions.
Circular regions of interest (ROI) were defined around the source position to obtain the total ROI value.
STEM HAADF image, presented in Fig. 4a, shows clearly these darker circular regions in the ZrO2 grains.
Then, multi-scale statistical analysis is performed on intensities of local circular regions centered in each pixel.
Besides, the unidirectional composites tend to form oval-shaped damaged regions while the quasi-isotropic laminates form almost circular regions.
Furthermore, two circular regions of interest (ROIs) were identified corresponding to the simulated SLN size to obtain the contrast and noise values.
On the reconstructed image, a series of circular regions of interest (ROIs) were projected onto the spheres, selecting the slice with peak value.
