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.
