While trying to understand the SGBM, I came across the SGBM3Way. I am aware that SGBM uses either 5 or 8 directions while calculating the directional cost and SGBM3Way uses 3 directions for the cost calculation.

Can anyone explain the difference between SGBM and SGBM3Way in respect of implementation. Why and how the parallelism was achieved in SGBM3Way and why there is no parallelism in SGBM?

Thanks in advance

Hello,

I am trying to understand the basic implementation of SGBM to parallelize the code. I thought that the cost calculation was one that can be separated from the main method and do parallel operations and give the cost input to the aggregation module.

Am I in the right direction ?

Will it be possible to do optimization as the aggregate cost calculation was dependent on different directions and some directions traverse bottom to top and vice verse.

Will there be any other way to do optimization ?

Thanks in advance
