| hi, could someone suggest me names of some filters of VirtualDub (internal or external) which are widely used (in real life applications & industry). I require filters which have high arithmetic complexity ..i could find general convolution as one such. Plz suggest other filters which are complex and also widely used. TIA, apa |

| Spatial noise reduction filters based on bilateral filters (weighted average by similarity to center pixel) are very computationally expensive filters. They don't always run in real time even on the GPU. Edge Directed Interpolation (EDI) based resamplers are also expensive due to the process of accumulating the covariance matrix. The average operation count can be reduced by using a tree structure but that makes the algorithm more complex. |

| hi, Thanx for your reply.It would be very helpful if you provide me with source code of filters you mentioned. I searched for them extensively but couldn't find the exact one. I would try porting them on Gpu and see the performance...... TIA, apa |
