... smoothstyle =`adaptive'. This is exactly the same as the patchwork convolution described in section 3.3.4 , except here the task calculates the library of convolvers and the associated index image itself. ... The task actually makes two passes through the library of gaussians: the first as described above, to calculate the index image; the second refers to the index image while performing the convolution, exactly as described in section 3.3.4 . ...

Next: Results Up: Adaptive Regularized Restoration Algorithms Previous: Introduction . For the algorithms discussed here, the restoration approaches have been formulated to handle the problem of an image degraded by a spatially invariant or spatially variant blur operator with additive Gaussian noise. ... Iterative approaches may be used to solve this inverse problem very effectively. ... In order to solve for an optimal restored image and regularization parameter at each iteration, we use . ...

Each Apache configuration directive is described using a common format that looks like this: . ... This indicates the format of the directive as it would appear in a configuration file. This syntax is extremely directive-specific, and is described in detail in the directive's definition. ... If the directive has a default value ( i.e. , if you omit it from your configuration entirely, the Apache Web server will behave as though you set it to a particular value), it is described here. ...

... The evolution of a binary system can be described as the movement of a point in the parameter space , constituting both physical quantities (such as masses of binary components, their radii, luminosities, orbital period, etc., independently of direct observational measurability of these values Each binary traces a path (which we will call a ``track'') in this space, in a way strictly determined by the evolutionary scenario. ... Then the fraction of binaries lying inside is expressed by . ...
