C Specification

The optical flow session binding points are defined with the following:

// Provided by VK_NV_optical_flow
typedef enum VkOpticalFlowSessionBindingPointNV {
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_UNKNOWN_NV = 0,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_INPUT_NV = 1,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_REFERENCE_NV = 2,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_HINT_NV = 3,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_FLOW_VECTOR_NV = 4,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_FLOW_VECTOR_NV = 5,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_COST_NV = 6,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_COST_NV = 7,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_GLOBAL_FLOW_NV = 8,
} VkOpticalFlowSessionBindingPointNV;

Description

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_INPUT_NV specifies the binding point for the input frame.

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_REFERENCE_NV specifies the binding point for the input reference frame.

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_HINT_NV specifies the binding point for the optional external hint flow vectors.

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_FLOW_VECTOR_NV specifies the binding point for output flow vectors of default forward flow calcution.

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_FLOW_VECTOR_NV specifies the binding point for the optional output flow vector map of optional backward flow calcution.

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_COST_NV specifies the binding point for the optional output cost map of default forward flow calcution.

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_COST_NV specifies the binding point for the optional output cost map of optional backward flow calcution.

  • VK_OPTICAL_FLOW_SESSION_BINDING_POINT_GLOBAL_FLOW_NV specifies the binding point for the optional global flow value of default forward flow calcution.
