reads the blobs found in a directory of images and produces intensity features

The component requires that all the columns from ImageBlobDetect are still found in the data file.

Usage Example with default values

Inputs

Name Type Mandatory Description
images ImageList Mandatory A directory with grayscale image files.
objects CSV Mandatory List of locations for the objects.
names ImageList Optional A directory with the original image files, for naming the table. If omitted, names from "dir" are used.

Outputs

Name Type Description
out CSV Intensity features.

Parameters

Name Type Default Description
erodeWidth float 30 Erosion width to calculate margination in pixels or percentage of object length. Erosion width can be negative, which means the object will be dilated.
isRatio boolean true Eroding width is expressed in percentage of object width instead absolute pixels.
overlap boolean false Calculate object overlap percentage. (Very slow). With this feature also Margination with negative erosion is calculated more acurately, so that the outer intensity does not cross other objects' insides.
prefix string " " Prefix string for margination headers in the result table. Used when reading the same images with multiple parameters and the joining the results.
