Structure to hold parameters for the FAST corner detector.

Public Members

int32_t circleRadius

The radius of the circle around a pixel used for corner detection.

int32_t arcLength

The arc length defines the number of contiguous pixels on the circle that are considered during corner evaluation.

uint8_t nonMaxSuppression

Specifies whether non-maximum suppression should be applied to refine corner detection results.

int32_t numTopKFeatures

Number of highest-scoring corners to return using TopK feature selection. When set to 0 (default), TopK is disabled and all detected corners are returned. When set to a value in [1, PVA_FAST_CORNER_MAX_TOPK_FEATURES], the operator uses histogram-based score thresholding to return approximately the K highest-scoring corners.
