Re: Making a Poster
Starting from version 1.0.30 the Graff has new valuable features. We shell use them in the new variation of poster creation. 1. After opening a photo, in the menu go to Filter->Other->High Pass . Chose the radius equal to 3 and press OK button. This will perform high pass filter, i.e. we get only hi...

Re: Multigrid methods enchancement.
For the non-linear case we took another problem, but still based on Poisson equation: L[u(x,y)] = u(x,y) - f(x,y) , where L no is a non-linear operator. Again, we compare the performance of different cycles in milliseconds, using the fastest configuration for each cycle to achieve the accuracy less ...

The cascadic multigrid method for elliptic problems
It looks like cascadic multigrid is very common to O-cycles.

Re: Visir px Release Candidates
The OpenCV library should be installed. We work now on supplementing the archive with all the necessary dll and lib files.

Re: Multigrid methods enchancement.
- As we can see, the SID enchants the performance from 10% up to 70% depending on cycle used. - Using o-cycles gives a very good performance but yields to v-cycle performance. - O-cycles with SID were used in the article "Accurate Real-Time Disparity Estimation with Variational Method". L...

Multigrid methods enchancement.
We continue our research on fast boundary problems solver. As was described in the article "Accurate Real-Time Disparity Estimation with Variational Method" , the multigrids methods are very efficient in that contest. In the same article we have offered a new kind of multigrid cycles - O-c...

Re: Graff desaturation
Currently we use the following desaturation algorithm: C = (R + G + B) / 3.
Before committing a bug, I suggest to discuss desaturation here.

Poisson Equation
Currently I work on the new approach to multigrids methods for Poisson equation resolving. It continues my recent work, described in paper Accurate RT Disparity Estimation with Variational Metod . A pretty interesting result, that I would like to publish here is the residual r(x,y) = f(x,y) + L[u(x,...
