VkOpticalFlowGridSizeFlagBitsNV(3)

Name

VkOpticalFlowGridSizeFlagBitsNV - Bits specifying grid sizes for optical flow operations

C Specification

Optical flow vectors are generated block-wise, one vector for each block of NxN pixels (referred to as grid).

Bits which can be set in VkOpticalFlowSessionCreateInfoNV::outputGridSize and VkOpticalFlowSessionCreateInfoNV::hintGridSize, or which are returned in VkPhysicalDeviceOpticalFlowPropertiesNV::supportedOutputGridSizes and VkPhysicalDeviceOpticalFlowPropertiesNV::supportedHintGridSizes controlling optical flow grid sizes, are:

// Provided by VK_NV_optical_flow
typedef enum VkOpticalFlowGridSizeFlagBitsNV {
    VK_OPTICAL_FLOW_GRID_SIZE_UNKNOWN_NV = 0,
    VK_OPTICAL_FLOW_GRID_SIZE_1X1_BIT_NV = 0x00000001,
    VK_OPTICAL_FLOW_GRID_SIZE_2X2_BIT_NV = 0x00000002,
    VK_OPTICAL_FLOW_GRID_SIZE_4X4_BIT_NV = 0x00000004,
    VK_OPTICAL_FLOW_GRID_SIZE_8X8_BIT_NV = 0x00000008,
} VkOpticalFlowGridSizeFlagBitsNV;

Description

VK_OPTICAL_FLOW_GRID_SIZE_1X1_BIT_NV specifies that grid is 1x1 pixel.
VK_OPTICAL_FLOW_GRID_SIZE_2X2_BIT_NV specifies that grid is 2x2 pixel.
VK_OPTICAL_FLOW_GRID_SIZE_4X4_BIT_NV specifies that grid is 4x4 pixel.
VK_OPTICAL_FLOW_GRID_SIZE_8X8_BIT_NV specifies that grid is 8x8 pixel.
