C Specification
Optical flow exposes performance levels which the application can choose based on the desired performance and quality requirement.
The optical flow performance level types are defined with the following:
// Provided by VK_NV_optical_flow
typedef enum VkOpticalFlowPerformanceLevelNV {
VK_OPTICAL_FLOW_PERFORMANCE_LEVEL_UNKNOWN_NV = 0,
VK_OPTICAL_FLOW_PERFORMANCE_LEVEL_SLOW_NV = 1,
VK_OPTICAL_FLOW_PERFORMANCE_LEVEL_MEDIUM_NV = 2,
VK_OPTICAL_FLOW_PERFORMANCE_LEVEL_FAST_NV = 3,
} VkOpticalFlowPerformanceLevelNV;Description
-
VK_OPTICAL_FLOW_PERFORMANCE_LEVEL_SLOW_NV is a level with slower performance but higher quality.
-
VK_OPTICAL_FLOW_PERFORMANCE_LEVEL_MEDIUM_NV is a level with medium performance and medium quality.
-
VK_OPTICAL_FLOW_PERFORMANCE_LEVEL_FAST_NV is a preset with higher performance but lower quality.
