VkDataGraphOpticalFlowExecuteFlagBitsARM

Bits which can be set in VkDataGraphPipelineOpticalFlowDispatchInfoARM::flags, controlling optical flow execution, are:

typedef enum VkDataGraphOpticalFlowExecuteFlagBitsARM {
    VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_DISABLE_TEMPORAL_HINTS_BIT_ARM = 0x00000001,
    VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_INPUT_UNCHANGED_BIT_ARM = 0x00000002,
    VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_REFERENCE_UNCHANGED_BIT_ARM = 0x00000004,
    VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_INPUT_IS_PREVIOUS_REFERENCE_BIT_ARM = 0x00000008,
    VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_REFERENCE_IS_PREVIOUS_INPUT_BIT_ARM = 0x00000010,
} VkDataGraphOpticalFlowExecuteFlagBitsARM;

pub struct DataGraphOpticalFlowExecuteFlagBitsARM(u32);
impl DataGraphOpticalFlowExecuteFlagBitsARM {
    pub const DISABLE_TEMPORAL_HINTS: Self = 0x00000001;
    pub const INPUT_UNCHANGED: Self = 0x00000002;
    pub const REFERENCE_UNCHANGED: Self = 0x00000004;
    pub const INPUT_IS_PREVIOUS_REFERENCE: Self = 0x00000008;
    pub const REFERENCE_IS_PREVIOUS_INPUT: Self = 0x00000010;
}

• VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_DISABLE_TEMPORAL_HINTS_BIT_ARM specifies that temporal hints from previously generated flow vector map are not used. If temporal hints are enabled, the optical flow vector map from previous vkCmdDispatchDataGraphARM calls in the same graph pipeline session may be automatically used as hints for the current vkCmdDispatchDataGraphARM call, to take advantage of temporal correlation in a video sequence. Temporal hints should be disabled if there is a-priori knowledge of no temporal correlation (e.g. a scene change, independent successive image pairs).
• VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_INPUT_UNCHANGED_BIT_ARM specifies that the contents of the input image are the same as in the previously executed vkCmdDispatchDataGraphARM call in the same graph pipeline session.
• VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_REFERENCE_UNCHANGED_BIT_ARM specifies that the contents of the reference image are the same as in the previously executed vkCmdDispatchDataGraphARM call in the same graph pipeline session.
• VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_INPUT_IS_PREVIOUS_REFERENCE_BIT_ARM specifies that the contents of the input image are the same as the contents of the reference image in the previously executed vkCmdDispatchDataGraphARM call in the same graph pipeline session.
• VK_DATA_GRAPH_OPTICAL_FLOW_EXECUTE_REFERENCE_IS_PREVIOUS_INPUT_BIT_ARM specifies that the contents of the reference image are the same as the contents of the input image in the previously executed vkCmdDispatchDataGraphARM call in the same graph pipeline session.
