Accessor of the details channel of the retina (models foveal vision)

parvo = obj.getParvoRAW()

Output

• parvo the output buffer, format can be:
  • a matrix, this output is rescaled for standard 8bits image processing use in OpenCV
  • RAW methods actually return a 1D matrix (encoding is R1, R2, ..., Rn, G1, G2, ..., Gn, B1, B2, ..., Bn), this output is the original retina filter model output, without any quantification or rescaling.

Warning, getParvoRAW methods return buffers that are not rescaled within range [0;255] while the non RAW method allows a normalized matrix to be retrieved.
