## Name

VkDataGraphOpticalFlowPerformanceLevelARM - Optical flow performance level types

Loading… please wait.

## 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_ARM_data_graph_optical_flow
    typedef enum VkDataGraphOpticalFlowPerformanceLevelARM {
        VK_DATA_GRAPH_OPTICAL_FLOW_PERFORMANCE_LEVEL_UNKNOWN_ARM = 0,
        VK_DATA_GRAPH_OPTICAL_FLOW_PERFORMANCE_LEVEL_SLOW_ARM = 1,
        VK_DATA_GRAPH_OPTICAL_FLOW_PERFORMANCE_LEVEL_MEDIUM_ARM = 2,
        VK_DATA_GRAPH_OPTICAL_FLOW_PERFORMANCE_LEVEL_FAST_ARM = 3,
    } VkDataGraphOpticalFlowPerformanceLevelARM;

## Description

- VK_DATA_GRAPH_OPTICAL_FLOW_PERFORMANCE_LEVEL_SLOW_ARM is a level with slower performance but higher quality.

- VK_DATA_GRAPH_OPTICAL_FLOW_PERFORMANCE_LEVEL_MEDIUM_ARM is a level with medium performance and medium quality.

- VK_DATA_GRAPH_OPTICAL_FLOW_PERFORMANCE_LEVEL_FAST_ARM is a preset with higher performance but lower quality.
