the contour approximation algorithm

Variants

CHAIN_APPROX_NONE = 1

stores absolutely all the contour points. That is, any 2 subsequent points (x1,y1) and (x2,y2) of the contour will be either horizontal, vertical or diagonal neighbors, that is, max(abs(x1-x2),abs(y2-y1))==1.

CHAIN_APPROX_SIMPLE = 2

compresses horizontal, vertical, and diagonal segments and leaves only their end points. For example, an up-right rectangular contour is encoded with 4 points.

CHAIN_APPROX_TC89_L1 = 3

applies one of the flavors of the Teh-Chin chain approximation algorithm TehChin89

CHAIN_APPROX_TC89_KCOS = 4

applies one of the flavors of the Teh-Chin chain approximation algorithm TehChin89

Trait Implementations

impl Clone for ContourApproximationModes

fn clone(&self) -> ContourApproximationModes

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContourApproximationModes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ContourApproximationModes

fn eq(&self, other: &ContourApproximationModes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
