DRAW_HEATMAP
DrawHeatMapStep is a a pipeline step that configures how to draw a 2-D heat map on an image.
Configs
Descriptions
points
Name of the input data fields containing the points used for the heat map. Accepts both single points and lists of points. Accepts both relative and absolute addressed points.
radius
Size of area influenced by a point.
fadingFactor
Fading factor. 0 is no fade and 1 is instant fade.
image
An optional field, specifying the name of the image to draw on.
opacity
Opacity of the heat map. Between 0 and 1. 0 is fully transparent and 1 is fully opaque. Default is 0.5.
width
Must be provided when image is not set. Used to resolve position of points with relative addressing (dimensions between 0 and 1).
height
Must be provided when image is not set. Used to resolve position of points with relative addressing (dimensions between 0 and 1).
outputName
Name of the output image. Default name is set as image.
keepOtherValues
true by default. If true, copy all the other (non-converted/non-image) entries in the input data to the output data.
imageToNDArrayConfig
Used to account for the fact that n-dimensional array from ImageToNDArrayConfig may be used to crop images before passing to the network, when the image aspect ratio doesn't match the NDArray aspect ratio. This allows the step to determine the subset of the image actually passed to the network. Refer config from IMAGE_TO_NDARRAY.
