Expensive digital projection systems, which would save the studios the cost of producing thousands of prints and guarantee moviegoers a pristine film each time, were once again on wide display.
This means that the computationally expensive ICA projection is unnecessary for further process and involved PCA process of ICA, whether PCA I or II, can be used directly for face recognition.
Because the film could be adapted to the requirements of individual theaters, movie houses did not need to install special, expensive 70mm projection equipment.
And without those expensive upgrades to projection equipment at the multiplex, mass market 3-D releases are not tenable.
Creating conference rooms (large, common offices) equipped with expensive, high-tech projection systems, speakerphones and video feeds.
What's more important is that, both the PAPA and the MPAPA algorithms require a M×M direct matrix inversion, which is especially expensive for high projection orders.
"It's clear that operations in Iraq and Afghanistan have gone on longer and have been more expensive than the projections initially suggested," Peter R. Orszag, director of the Congressional Budget Office, said in an interview.
Thus computing the orthogonal projection is expensive.
He said it was too expensive (at the time, the projection was $28 billion for 682 aircraft) for what he viewed as the Marines' relatively narrow mission, amphibious assault.
Unfortunately, because the computing of projection is cost expensive, it cannot be used for upsampling points in real time.
