Struct opencv::objdetect::Dictionary

pub struct Dictionary { /* private fields */ }

Dictionary/Set of markers, it contains the inner codification

BytesList contains the marker codewords where:

• bytesList.rows is the dictionary size
• each marker is encoded using nbytes = ceil(markerSize*markerSize/8.)
• each row contains all 4 rotations of the marker, so its length is 4*nbytes

bytesList.ptr(i)[k*nbytes + j] is then the j-th byte of i-th marker, in its k-th rotation.

Implementations

impl Dictionary

pub fn default() -> Result<Dictionary>

pub fn new( bytes_list: &Mat, _marker_size: i32, maxcorr: i32 ) -> Result<Dictionary>

C++ default parameters

• maxcorr: 0

pub fn new_def(bytes_list: &Mat, _marker_size: i32) -> Result<Dictionary>

Note

This alternative version of [new] function uses the following default values for its arguments:

• maxcorr: 0

pub fn get_byte_list_from_bits(bits: &Mat) -> Result<Mat>

Transform matrix of bits to list of bytes in the 4 rotations

pub fn get_bits_from_byte_list(byte_list: &Mat, marker_size: i32) -> Result<Mat>

Transform list of bytes to matrix of bits
