3 Specifications

System Nodes

The implementation is composed of the following nodes:

RETINA:

• RetinaProcess: It is in charge of transduction, converting RGB images into activations of the LMS cones.
• BasicMotion: Perform motion detection by lighting difference, creating a binary matrix with the areas where there is movement or change.

LGN:

• LGNSimpleOpponentCells: Convert LMS activations to DKL color space

V1:

• V1DoubleOpponent: Performs the double opponent process on the DKL matrices, obtaining the D'K'L' matrices
• V1SimpleCells: Obtaining edges with specific orientations through convolutions with Gabor filters
• V1ComplexCells: Obtaining the spatial invariance of the edges
• V1HyperComplex: Obtaining the selectivity of edges with specific lengths
• V1BinocularSimpleCells: Obtains activation of binocular simple cells
• V1BinocularComplexCells: Obtains activation of binocular complex cells and normalized complex cells
• V1BinocularMergeProcess: It performs a fusion of the binocular activations of different filter types.
• V1MotionCellsNew: Detect edge movement with specific orientations, method is different compared to 2018 implementation

V2:

• V2AngularCells: Obtaining angular selectivity
• V2CurvatureCells: Specific curvature maps are obtained
• V2CornerMotion: Obtaining the movement of corners

V3:

• V3DisparityRange: Performs the relative disparity calculation

V4:

• V4SimpleShapeCells: Performs simple shape selectivity, without scale invariance
• V4SimpleShapeScaleInv: Join the simple shape patches of various scales into an activation map
• V4Color: Assign the color labels

MT:

• MTComponentCells: Merges V1 motion maps from different filter types, plus reduces resolution
• MTPatternCells: Calculates the pattern motion, then it creates an matrix of colors to display

MST:

• MSTPolarCells: Get the polar motion matrices
• MSTTemplateCells: Not implemented

Alert:

• AlertProcess: Change the sample rate or system animation with 3 alert levels

TestAttention:

• FeedbackProcess: Process to test the modulation mechanism, send a modulation matrix to several matrices
