C Specification

Optical flow exposes performance levels which the user 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.
