Embodiment Construction
[0011] The preferred embodiments of the present invention will be described in detail below; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.
[0012] The workstation adopts a CPU+GPU heterogeneous parallel computing system, which is a group-core supercomputing system composed of a subsystem with a multi-core CPU as the main processor and a subsystem with many cores and GPUs as the co-processor. The supercomputing system is equipped with a host subsystem and two computing equipment subsystems, and all the equipment are connected through the PCI-Express×16 bus. The GPU is in the form of an external device and communicates with the CPU through the PCI-Express bus. Both the CPU and the GPU have their own storage systems, and data is transferred between them through DMA operations.
[0013] The Harris operator only uses the first derivative of the image data ...
