RETURN TYPEbioinspired_Retina | null
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

inputSize

the input frame size

_1

1 argument (boolean).

_2

2 argument (number).

colorMode

the chosen processing mode : with or without color processing

colorSamplingMethod

specifies which kind of color sampling will be used :

  • cv::bioinspired::RETINA_COLOR_RANDOM: each pixel position is either R, G or B in a random choice
  • cv::bioinspired::RETINA_COLOR_DIAGONAL: color sampling is RGBRGBRGB..., line 2 BRGBRGBRG..., line 3, GBRGBRGBR...
  • cv::bioinspired::RETINA_COLOR_BAYER: standard bayer sampling
useRetinaLogSampling

activate retina log sampling, if true, the 2 following parameters can be used

reductionFactor

only usefull if param useRetinaLogSampling=true, specifies the reduction factor of the output frame (as the center (fovea) is high resolution and corners can be underscaled, then a reduction of the output is allowed without precision leak

samplingStrength

only usefull if param useRetinaLogSampling=true, specifies the strength of the log scale that is applied

Returns

The bioinspired_Retina | null result.
