I implemented a registration pipeline using MattesMutualInformation as the metric algorithm.
I am reaching convergence around 50 iterations but these iterations are taking nearly 4 minutes. My computer has an i7-9750, 16GB RAM, and an Nvidia RTX 2060 6GB.
I tried setting up the WorkUnits but no improvement was noticed. I looked into some questions on the forum regarding the GPU implementation and, as far as I understood, there isn’t a current implementation of the registration framework on the GPU.
The moving image is 640x402 and the fixed image is 640x480. Is processing time normal? Is there a way in which I can use the GPU or use more threads?
