As an additional index of image complexity, the entropy of each grayscaled image was determined.
The value of the speckle temporal contrast C at pixel (x, y) was calculated as where I i is the light intensity of the ith laser speckle image, σ is the standard deviation of intensity, i is the index of image in the sequence, and N is equal to the total number of images recorded.
One is WholeWeb.net, a search-engine company that is creating a program that its founders say will be able to match scanned photographs to an index of images found on the Web.
Anisotropy indices of the image planes ranged from 0.08 to 0.45.
As the attached data also contains the start and end indices of the image group, the control station now computes the expected accumulated hash sum for the frames indicated by the start and end indices.
We conduct comprehensive experiments to measure the performance of the algorithm in terms of visual evaluation and a variety of quantitative indices for image segmentation.
In this paper, we illustrate several project management tasks and show how Content-Based Search Engines can facilitate automatic retrieval, and indexing of construction images in image databases.
The vector at the input of the clutter reduction system, and its relationship with the original image is described in (1) for a vertical mode, being and the row and column indexes in the image, respectively, and the index of the image in the set.
Maebatake et al. used phantom studies based on the relationship between the noise equivalent count (NEC), as an index of PET image quality and TOF-PET image quality for 18F-FDG PET/CT showing similar results regarding the impact of PSF and TOF [40].
From the regression analysis, it resulted b = − 0.54 ± 0.07 (with r 2 = 0.86), indicating that the homogeneity index is representative of image noise (thereby associated with low counting statistics) and it is likely to decrease in proportion to the square root of the number of emitted positrons.
