Enum Fast

Source 
pub enum Fast {
    Nine,
    Twelve,
}
Expand description

Variants of the FAST corner detector. These classify a point based on its intensity relative to the 16 pixels in the Bresenham circle of radius 3 around it. A point P with intensity I is detected as a corner if all pixels in a sufficiently long contiguous section of this circle either all have intensity greater than I + t or all have intensity less than I - t, for some user-provided threshold t. The score of a corner is the greatest threshold for which the given pixel still qualifies as a corner.

Variants§

§

Nine

Corners require a section of length as least nine.

§

Twelve

Corners require a section of length as least twelve.
