Struct corr2d_state_t¶

ClassList > corr2d_state_t

2-D FFT correlator state. More...

• #include <corr2d_core.h>

Public Attributes¶

Detailed Description¶

Allocate with corr2d_create(); never stack-allocate. All heap buffers are ny * nx complex floats stored in row-major order.

Public Attributes Documentation¶

variable accum¶

float complex* corr2d_state_t::accum;

Coherent product-spectrum accumulator.

variable count¶

size_t corr2d_state_t::count;

Frames accumulated (0 … dwell-1).

variable dwell¶

size_t corr2d_state_t::dwell;

Integration depth.

variable fwd¶

fft2d_state_t* corr2d_state_t::fwd;

Forward 2-D plan (sign = -1) at (ny, nx).

variable inv¶

fft2d_state_t* corr2d_state_t::inv;

Inverse 2-D plan (sign = +1) at (ny_out,…).

variable n¶

size_t corr2d_state_t::n;

ny * nx — total element count.

variable n_out¶

size_t corr2d_state_t::n_out;

variable nx¶

size_t corr2d_state_t::nx;

Column count.

variable nx_out¶

size_t corr2d_state_t::nx_out;

Output columns (== nx unless decoupled).

variable ny¶

size_t corr2d_state_t::ny;

Row count.

variable ny_out¶

size_t corr2d_state_t::ny_out;

conj(FFT2(ref)), pre-computed. (ny, nx)

variable work_fft¶

float complex* corr2d_state_t::work_fft;

Scratch: FFT2(in) · ref_spec (product).

variable work_pad¶

float complex* corr2d_state_t::work_pad;

Zero-padded product, (ny_out, nx_out).

variable zcol¶

float complex* corr2d_state_t::zcol;

Column gather scratch, (ny).

variable zcolout¶
