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
VkDataGraphPipelineOpticalFlowCreateInfoARM::outputGridSize and
VkDataGraphPipelineOpticalFlowCreateInfoARM::hintGridSize, or
which are returned in
VkQueueFamilyDataGraphOpticalFlowPropertiesARM::supportedOutputGridSizes
and
VkQueueFamilyDataGraphOpticalFlowPropertiesARM::supportedHintGridSizes
controlling optical flow grid sizes, are:
// Provided by VK_ARM_data_graph_optical_flow
typedef enum VkDataGraphOpticalFlowGridSizeFlagBitsARM {
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_UNKNOWN_ARM = 0,
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_1X1_BIT_ARM = 0x00000001,
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_2X2_BIT_ARM = 0x00000002,
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_4X4_BIT_ARM = 0x00000004,
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_8X8_BIT_ARM = 0x00000008,
} VkDataGraphOpticalFlowGridSizeFlagBitsARM;Description
-
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_1X1_BIT_ARM specifies that grid is 1x1 pixel.
-
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_2X2_BIT_ARM specifies that grid is 2x2 pixel.
-
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_4X4_BIT_ARM specifies that grid is 4x4 pixel.
-
VK_DATA_GRAPH_OPTICAL_FLOW_GRID_SIZE_8X8_BIT_ARM specifies that grid is 8x8 pixel.
